Bleaching Hair | What Developer, Low And Slow Or Fast And Furious? |

shockalockabocka: I think rules like this from American and European stylists are good guidelines for their target market audience - Caucasian, normal to fine hair. But I do a lot of Asian hair with a tight, resistant cuticle and if I did low and slow I’d have a lot of unwanted redheads walking around or really long processing times. I think stylists need to use common sense and our knowledge of texture, porosity, density and starting level to determine formulas.

david19957: A good experiment would be to compare the integrity of the hair when you use 40 vol vs 10 vol until you reach the same colour with both developers .

I Believe: Now you should tone them all to see how much red will be removed at those orange levels so people can see nothing will happen when hair is not light enough.

Hilary Garstang: The side by side comparison is really helpful! I lean towards low and slow on new clients with fine or curly hair, but for the most part I stick with 30, sometimes with a splash of 40. Many of my lightening clients involve additional processes, so I don’t want to spend too much time waiting for lift. I like to get in and out with the bleach and move on. That being said, maintaining the integrity of the hair is always the top priority.

hanna: me watching this while getting ready to bleach my asian hair w 40 vol lol

Very Naughty Kitty: I'm not a licensed professional . but my grandmother was and she taught me the basics of bleaching and processing hair . myself and my best friend have the most difficult to process . my best friend has Native American and Asian hair so she's got thick dark hair coarse hair that's out of level one and the quantity of your hair is medium on her head .myself I have Italian and check hair with my hair I'm a level 2 I have thick hair its course and I have a large quantity of hair on my head. the both of us have to double process our hair we start off with a level 30 we go up to about 45 minutes we wash our hair and assess and then we go back in with a level 20 for about 20 to 25 minutes to depending on how much lift we got on the first round and the Integrity of the hair. myself I find that's the safest way to get to a level 10 for us to put in best semi-permanent color like the blues and purples and pinks with doing minimal amount of damage. that's my personal opinion for not being a professional.

Lila T: Absolutely LOVE this!!! I have super dark, thick, hair, about a level 3 SUPER DARK, and my stylist ALWAYS starts my highlights at 30vol so by the time she's halfway done, it's already been awhile, and she moves up to the 40vol so that my highlights will be even. But even with 40vol dev, we leave the foils in for at LEAST 2 hours total (sometimes longer) and will still need to repeat the highlights after 2 weeks because they just don't lift high enough.. damage is pretty minimal, though I do trim my hair every 4-6 weeks a tiny bit, and only wash about twice a week, and don't use any heat for styling anymore, plus sleep with a silk pillowcase, use a silicone mix leave in treatment often, and argan oil on the ends regularly. But usually the second round of bleach w/ 40vol, the worst that happens is some hair breaks off the first couple weeks, since I have super thick hair, I don't mind it at all, plus it gives me a textured hair cut lol. But yeah, when I tell people I use 40 vol for my bleach, they are like, "NOOO do LOW AND SLOW!" I'm like, but duuuude, I use HIGH and slow, I'm not using the high volumes for faster lift... I'm doing it for a HIGHER lift, and still have to leave it on as long as others would with a 20 vol.

NikiKL: Interesting stuff! Thanks! ... Did you do elasticity tests on the pieces after? Honestly I expected the 30 and 40v to go a little lighter.

Naomi Baram: The fact that this video is 11 minutes and 11 seconds is so satisfying

Alicia Marie: This is amazing! You’ve explained this so easily! Easier than some hair colorists I’ve seen on YouTube.

Jane Smith: You do the most interesting experiments. This was very enlightening for me. I do wish we could have done a damage assessment on each one after but I'm thinking that an Olaplex treatment afterwards along with good hair care could probably take care of any damage on typical hair. Thanks, James!

Adrienne Boullianne: james, you are a real gift to us in this industry! thanks for doing the work for all of us!

Theresa Nelson: Enjoy watching your videos and have learned quite a bit. I would still much rather have my hairdresser do this than myself, but since the Covid has put a limit on getting our hair done I’m almost forced to try this myself. Now I am not a hairdresser by no means, but I’m getting older my hair is naturally auburn and the older I get the lighter it gets, and of course getting gray. so I would like to get ahead of this and put some highlights in my hair. I am scared to death so I have been looking at professional hair videos to get an idea on how to do this, kind of like buying a car! get the facts before you take it out. So my question is... hair dyes and highlights that you get from a store are definitely not equivalent to the ones that you purchase online from professionals. What would be their ratio per box high or low the 10% that you showed in this video? And in order to lighten my hair without getting a orange or brassy look what would I use? Thanks again for the video and I understand if you cannot comment on this. But a thumbs up at least if you read it would be nice thanks again

Char Nith: Thank you for this video! Very insightful and informative. Hard to find a video experimenting developers with Asian hair and this is so detailed! I agree with your point. Following the guidelines is safer since it is how the product is supposed to be used.

Raphaela Pareto: I do have black asian hair and when I went to to my hair stylist (to get a purple hair), she used different volumes in different parts of my hair... but from what I heard her talking to the assistant, she used 10, 20 and 30v... It took more than two hours to lift until a pale yellow, but I felt basically no damage afterwards... I mean, really back in the past I did have a perm and the hair felt more dried on those days than recently, after bleaching... Olaplex miracles, maybe?

Track Fish: The hydrogen gas is what makes the higher developer lighten the hair faster. It appears to be working faster as there is a fast paced lifting stage when it is lifting however it slows down not long after because the percentage is higher. This would absolutely work for an expert when they are relying on little time however it can be dangerous to strip colour out of the Cortex to a high level very quickly if the hair is in any way compromised or has limitations to begin with. I loved your analysis and I think your are very articulate within your narration when delivering video content. Great work!

Syd: I found this video, as someone who has processed hair I'm looking to trying to lighten my hair as much as possible to have a more vibrant color than what I have now. A friend of mine had told me a 20 vol would be safer for me because my hair is fine and also has been processed before but still strong. I've been botched by my own stylist where she didn't seem to really care about the unevenness of the bleaching process and she didn't even tone my hair. So I'm attempting to do it myself. My hair is at a level 3-4 with silvery blue ends. Any advice I'd appreciate!

Zentina: Just recently found your channel. I have to say probably one of the best tutorials on hair and techniques. I love how you think outside the box, lots of great tips. I’ll be bleaching my hair in a month or two and this has helped me a lot. What kind of mask or treatment would you recommend after bleaching the hair? I’ve heard people will use some kind of treatment after to help the hair not be so dry.

Blue Bird: Could you repeat this experiment but in reverse, using a dark permanent hair color on the bleached strands and compare how fast the different developers activate/oxidize the color at each level?

임으니 Dwell on Jen: Hello! The video was very informative thank you! I have one question though, I just bleached my hair with a 40 developer, and after seeing this video I'm very concerned about my scalp and hair :'( while rinsing after bleach, there were no clumps of hair that fell out or anything, then would that mean it wasn't too much damage?? Also, what would you recommend to do after bleaching to keep the hair healthy?? Thank you so much for the video!

Immaculate Umutoni: This was soooooooooooo educational and more insightful than any video of colouring I’ve ever watched! Thanks so much for your professionalism!! You rock you just gained a new subscriber!!

Cii Cii: I have been touching up my roots with bleach/ 40 vol every few months for the last 15 years. I got pregnant at the beginning of last year and just let my hair grow out. As soon as he popped out I did my whole head with 40 vol twice 3 weeks apart and then toned and I’m back to my platinum. Still healthy too! It was nice to let it grow out fresh and healthy so it’s actually soft and thick too. I’m not Asian but have the darkest brown hair and it’s very resilient so 40 works good for me.

TomJames Bennett: This was really helpful. When I trained we were always told low and slow. Infact. I’ve never used 40vol in someone’s hair ever out of the pure fear that was drilled into me!

Shaun C: Hi James. Thank you for making this interesting video. I once worked in a salon where the owner and her junior stylists always used 60 vol YES 60vol! with bleach to lift her cap hi lights to pale yellow quickly, this method fitted in with her busy column. I was always terrified of the damage being caused, and the integrity of the hair after the colour service. I now only use 40 vol with high lift tints and use 30 vol max with bleach. The trouble is in a busy salon setting you don't have dream time to do the low and slow method then reapply another application after. I like how the Japanese and Korean salons have 2 stylists applying the product, which saves time and ensures of an even application. I used to work a lot with Scruples products which aren't well known here in the UK. They do an excellent hi lighting colour system called Blazing Hair. You only use 20 vol max even on very dark hair and you add the colour tone into the lightener so it lifts and tones all in one, a bit like Wella Magma but more of a true tone. I've always been scared of colour, when I was training you focused more on technique rather than the technical side. Salons need to ensure up and coming stylists understand the technical side of colour as well as the techniques used to get the desired results. Regards Shaun

Shawn Greene: Thank you so much for making this video. I have very similar hair to the tested strand. It was very nice to see a visual representation of the different volumes and the speed at which they effect the same hair sample. I want to achieve silver hair but after using 40 volume on my hair I don't know what process to use after. If I need to use a toner or if I need to use purple shampoo/conditioner or if I need to bleach my hair twice. I have much more research to do before I attempt this on my hair.

Kerry Grant: Thank you so much for sharing. I'm no professional but I colour my hair alot at home I never use box dyes/bleach etc. I always buy professional products but for a long time I always thought the lower developer % = less damage but now from watching this video I now know that is not true. Thank you I've been learning a lot from your videos

Alisha Gendu: Super great video. Really interesting illustration and experiment ! Bleach formulation itself is so important. Wholesale beauty places in my community have really low cost but high quality developer and blue powder bleach. I've always had my best success with powder as it thickens with developer so that you can fully saturate the hair. With box bleach it was always too runny and they go with their own ratios that may not always give desired consistency. They also mix other chemicals for scent that really doesn't matter or contribute to colour at the end. Also wear gloves always lol I lifted my hair four times, the first two times I went in brave hand painting but then my skin started peeling quite bad and burned a lot. I'm basically saying I've learned to use gloves, they are great, don't be lazy like me.

Christopher Mitchell: Great Information and I really love your videos . I’ve been in the game 30 years and knowing these kind of details sets you apart - I use volume and lift to my advantage when mixing - use the lower volumes as lowlights and higher as high . Etc etc - Knowledge is power! Keep sharing !

khris cornell: Thanks for this video to be honest I didn’t know u could use 10 to bleach at all and I’ve always been on the fence about using 40 so worried of the Damage all this was very informational and I so appreciate the video and I still agree with you about manufacturers directions

Beby Girl: Please make more videos, I’ve watched two so far, and have learned more than I do on others YouTube channels, and me and my niece do our own hair, so we need to see more videos like this.

Jessica Cisneros: That is great video. I think that it is important because just like you say, they are there for a reason. You need to consider your starting point and goal. You might need to use 10 vol developer if you're only looking to do a very soft lift, 40 if you work fast and you know the hair can take it. It's a matter of how fast you can apply the bleach and what your goal is. Definitely puts a good new perspective. Thank you!

A Repurposed Life with Laura: Love the comparison and knowing this was Asian hair. Great experiment.

Anni Baer: I bleached my hair today with the schwarzkopf blondme and 20 vol developer - the low and slow method is recomended on the packaging and it lifted beautifully

venetia fillery: Very interesting! I've just recently discovered The Life of Hair & its really helped me understand some basic principles of colour which I feel they don't explain in depth at college. Thanks so much James, its very much appreciated! :)

Eiscremefrau Neumann: I once had a woman walk into the salon asking if we could bleach her hair with 40% developer. We told her she probably meant 40 vol and that it wasn't even necessary because she was a level 7 naturally (but pretty damaged from highlights already). My co-worker said that they actually use 40% in turkey sometimes but where I live we can't even get that. I hope she didn't find someone who actually did this

Jennifer Hill: I bleached my dark brown hair twice in one day I used 30 vol and left it on for 40 mins and did it again. My hair is significantly lighter with no damage its like a bright orange/peach colour. It actually looks good however I am wanting to go blonde. Would you suggest doing it one more time with 30 volume for another 40 mins or should I leave it on for less time or use a lower vol with my hair already being very light already? Thanks

Shirumoon: I have bleached my hair with 3% (10 volume) and I'd like to redo my roots with 2%, because 3% was almost a bit too bright for me as I want to dye my hair orange anyways. Is that a good idea or should I just go with the 10 volume again?

fruity: My hair is about a level 7 lightness level and i want to get to maybe a 9, do you think i could do that with a 10 developer? Ive heard lots of different opinions that havent really been consistent with each other haha. I havent bleached my whole head before and have fairly fine hair but its not thin and is pretty healthy so i dont know if this means i should use a 10 or 20.

K. Waggoner: lmao, i used 40vol once on my naturally level 8 hair and it worked so fast i couldn’t get an even coverage. i swapped right back to my 20vol/30 minutes processing routine

Marina Parvanova: Nice video, so since the process time matters for the damage, what about those additional bonding substances like olaplex, matrix bond untim8, etc. Do they really help cut on the damage?

Diane LovesALotofLife: I used 30 volume in my bleaching mixture. I left the bleach on for 70 minutes. My hair turned almost white....and I had NO damage to my hair or scalp. I have dark brown/black hair. I only needed to process once to achieve almost white. Dark brown/black has should process for 60-70 minutes per manufacturers instructions, from the company. Medium to light blonde takes 20-25 minutes, light brown to dark blonde take 30-40 minutes, dark blonde to medium brown takes 45-60 minutes. And NEVER use hair dryers as a catalyst to bleach hair. Cover hair with cap, your head's natural heat is the perfect, consistent way to accelerate hair bleach. Never do more then 2-2 bleach processing of hair, as you will destroy your hair and scalp. Chemical hair processors...perms, dyes, bleaching absorbs into the scalp then into the blood stream...that is why you NEVER massage chemicals into the scalp. All hair stylists should be required to take a college cosmetology chemistry course to be certified to use chemicals on client's hair. I am an RN who took 4 chemistry courses in college and those course helped me to understand how "peroxide & bleach & perm solutions" work on our hair. You also, have to take in consideration a client's hair texture, skin tone & pigmentation, as those will tell you what volume of developer you should use and how to prevent dark hair from turning orange after bleaching.

Angeline: Hello! I'm fairly new to these hair products and processes and I was just wondering how did the mixtures get really thick? I know that the volume developers have more of a shampoo consistency, so I was wondering if he added something to them? and if he did, what is it?

ByTissa: My recent experience with a professional going fast and furious in my hair left me with bleeding at the top of my head and £260 poorer. There was a lot of rush into finishing my appointment post-locdown.

Updo Wedding Hairstyle Educational Tutorials: Looked like my daughter's science fair project...lol. Love trying things out like this. Personally I like fast because I get so stuck in a strong gold stage. Green eyed girl here. Being a level 6 I still need two process to get to plae yellow and I like the texture it gives me. I remember when flat irons came out we were cooking the foils in the irons Thanks James!!

Cyndi Lucero: Thank you!! I’m a pharmacy technician and not a cosmetologist, I’m trying to color my hair topper (as I’m balding from weight loss surgery), I followed a video to quickly lighten the hair, yet my wig is now orange (with BE2 and 30 volume) grrr! I knew I should’ve used the 40 volume developer but instead used 30 as that’s what was told! I’m swear one day I’m going to have my own wig line so others don’t have to go through what I am!!

Valentino Yazzie: My hair is naturally a level 2 neutral and I use level 20 with bleach for the 50 mins and I get to a level 7 or 8 mostly yellow with a bit of orange. I think it could be how healthy the hair is and the technique and quality of products that determine lift.

TL YN: Im new to your channel and appreciate your instructional videos very much. Have you done a side by side comparison for different bond builders like olaplex, cureplex, continuum, etc!? Would love to hear your insight there!

Jayne Read: Wow, I've learned so much thank you! I have a question; I have baby fine, fragile medium/dark blonde hair which my hairdresser highlights for me using foils. I have noticed that when she highlights my hair she puts the colour onto the full length of my hair. I have often wondered if she is continually over-processing the lower part of my hair whenever it's highlighted, because the my hair breaks so easily now. I think I would prefer to have some of my hair outside the foil.

Sharon Rose: Results will vary depending on your hair. My hair is as dark but it’s fine so both the 30 and 40 volume would leave my hair platinum blonde by 50 minutes.

Aj99: Hello! I've bleached my hair with 35 developer while leaving it in for 15-20 mins, I have dark brown hair. It didn't lift much and I have naturally thin hair. Id like to bleach it again, but I dont know how to choose a developer or how to know if my hairs strong enough! Any advice? Awesome video!

Abby Suh: As an Asian who has had my hair bleached a ton... only way my hair has a chance to lift is 40 volume double process (1:2). I’ve also Korean and apparently our hair is stubborn... it takes 4 double process bleaches to even get to a level 10 and it hardly damages my hair luckily.

Zahra: It was the best comparison of developers I've ever seen. Thank you so much❣

Seth Bourne: Love this, thank you. I usually choose my developer according to what I feel the hair can handle, the technique I’m using and time. Typically I spend most of my day foiling so I’m using 15 or 20 volume. On my global application I tend to use 20 or 30 volumes and balayage I always go for 40

Odalys Ruiz: Thank you! I believe it's like medicine. Every client needs a different method. And definitely no drier! I watch so much unnecessary damage! Love your videos! ✌✨

Bonnie Hu: I'm Asian and have been using the same litre-bottle of 40 vol for the past 3 years, bleaching my roots at roughly 5-month intervals. It's fine if you intend to keep your hair short. If I decide to grow my hair out though, I'll go with 30 vol next time.

Jennifer: I would never leave it on for more then 50 minutes. That is crazy. I always follow manufactures guide lines. That is very insightful full always want to know what different developers do. Thank you for showing me this.

Alexandra Stefan: I have bleached my hair with 40 vol and using that on scalp is extremely bad. I have personally not used it on scalp but I have seen someone who did and she had blisters and literally wounds on her scalp. I used it only on lenghts and it lightened my level 5 natural hair to level 9 really really fast, in 15 minutes. But I kept it longer and it damaged my hair really badly. So we better seek professional help if we want to go platinum blonde from brown hair. I am lucky to have a level 5 natural hair and I can use high lift dye to lift it to level 9 as high lift can lighten hair up to 5 levels so for me it is fine and even if it leaves it warm, I do mind warm tones in it so I don't mind a golden blonde. It lifts and tone it at the same time with less damage. I know this is a different topic and going back to bleach.....I personally won't ever use bleach with 40 vol anymore....it fried my hair really really badly. And not to mention people don't know and use 40 vol with bleach on scalp which is mind blowing. :) I am afraid to use 40 vol on scalp even with high lift dye however high lift dyes work differently and it seems that the manufacturers do recommend high lift dye with 40 vol as it is designed to lift with 40 vol to get maximum results and it definitely does not hurt scalp the same bleach does. But 40 vol....I am scared to use it tbh.

Desna Moon: Thank you James for this video. I am Filipino. My hair is black and long all the way down my back. The lower part the thinness. At the crown I’ve got a salt & pepper going on. I would like to go greyish black. So I thought I’d do the ponytail video and bleach it that way. Once I’m done with that do I use a grey/black hair dye or is there a type of toner I can use that would work? Thank you.

Stephanie: Higher volume levels in H2O2= more catalytic activity . It propels the hairs layers open at a higher velocity . It maybe fine on depths 4 and below- but an important factor , is to take in to account time..As you may need CONTROL . Control must be thought about. You may not want zones lifting so fast- then you you have to stop to remove them . Always take into account what techniques of applications you are using and the time they take to apply - before reaching for a high level peroxide

Kristina Sandnes: One of the hair dressers I went to a while back had the bleach in for at least 3 hours. My hair started breaking and flying off when they started combing my COMPLETELY wet, not dried at all, hair... with a small comb. It was true pain, and they did not stop when I wanted to do it myself. True nightmare.

Safirah Poulter: Hi, I really liked your video and found it very very useful. The fact that you used it on Asian hair was a bonus. I have a question. For highlights, would you use 40v with copper red colour to give it the attention I want? Saf x

imzarxki: me in quarantine trying to choose the right developer to bleach my hair :

karla noe: I'm using volume 30, my hair is pretty much like Asian hair. I've bleached it once and I have yellow and orange tones. My goal is ultimately to get it to a dark violet ash blonde as I don't think I suit extremely light hair

Caroline Cholmodeley: You have an interesting point ! I have started low and slow; however did 20 mins with Olaplaex however after watching your video I wish I had of gone to 9% . Honestly bleach is sooo bad it took me weeks to convince myself, albiit the sparkle got the best of me

Mc Max: Thank you so much for this information! I'm about to bleach my friend's hair and I'm pretty excited, I hope it turns out well even though I have bleached my own hair before, new sub from Mexico One quick question, if his hair is a natural (virgin) level 4 and he wants bright neon pink hair, should I lift to a level 9/10 or can I work with a level 8 as well? Hope you have a lot of success, you really deserve a lot of subs <3

REN: I’ve been using demi perm 3N for years (i have some white hair). Then for 6 months stopped, and used a clarifying shampoo biweekly. Went to the salon and my hair still wouldn’t lighten in some parts It was just so patchy and bad. I have thick coarse THICK asian hair. So goodbye my dreams of having colorful hair.

Heather G: Thank you for this James. I have done both, but it's either in foils or with plastic. I would think that would make the difference in end result with head heat, etc?

Cat: My natural hair is like a dark blonde ( 6-7) and I want to touch up my highlights which are at a 9. My hair develops fast, it's fine and porous. Should I use 20 or 30 developer?

I'mGrii: I never thought about it before, the more the bleach stays in the hair the more damage you are doing. I thinking the best way to use bleach is using the right developer for whatever you want to do, so i guess if a asian girl woth dark hair whants to go blonde, 40 volume it is and probably needs to add some heat to it so it lifts a bit more, inside the 50 mnts.

Stacy Young: You get your lift from the bleach itself or the tube of color your using. The developer is like the gas pedal. It's how fast you want to get from point A to B. Your choice as a stylist what the clients hair can handle.

Colette Grant: good points made here, just find low and slow good when doing full head highlighting so can allow for longer application process

Rita Falcão: Hi! My hair is dark brown, it has been colored with a reddish tone before and now it has a semi permenent copper color (it was never bleached). I wanted my hair to become auburn/copper. Do you think 10 volume would do or 20 volume would be better? Or do you think that there's no need to bleach to achieve that color?

Julia Vaoita Maeva Mareko: So I've tried all developer vols except for the 10 since my natural hair color is a level 2-3 (yes, I am mixed) so it would be a waste of time and money to use a lower volume on my stronghold hair. I definitely prefer volume 40 for my touch ups and rootlage. For all bleach processes, please add yr Olaplex O zero to help the cuticles repair after each lifting sesh. Also, ask someone to help you for the back of yr head bc time is of the essence when applying the bleaching so work fast but in a methodical approach for less clean up and messes.

Cosmic Angel: I used this on my natural hair and it went white with little damage I used olaplaex too though, I have very thin hair

C S: Your final results were 10 vol = 6, 20 vol = 7 and 6, 30 vol = true 7, and 40 vol = pretty close to 8. Check your redken color chart. It’s a lifesaver when it comes to lightening and toning. Good message about following manufacturers directions. Always a must. Period.

Matthias: Well you should pay attention to an even application and distribution of the product. Comparing the 10 vol strand to the 40 vol strand there is less product on the 10 vol strand than the 40 vol. For an even lift the hair should 'swim' in the product. Despite that a level 8 is reached when you have yellow, if orange is visible it is max a level 7. There is definitely no level 8 visible.

Lasca Young: I take longer to foil and I don’t want to over process. Would you remove foils that are done along the way or start with a lower volume on the first half and then up the volume on the second half?

T C: Thanks for using Asian hair! Finally feeling represented LOL

Amy Lou: I've been searching on google and youtube for a long time because I'm planning on lightening my hair from a brown, so I'm able to get some vibrant colour from semi permanent hair dye, and I found this video most useful so thank you. I'm wondering if you could help me put with the meaning of toner?

Catarina Duarte: i bleached my almost black hair with 20 volume and it turned almost white but it took hours to develop and my hair feels amazing

Alison Jetmar: Excellent tutorial. I watched it all! Thank you for sharing your expert knowledge!

nusrat nisha: This is the video I was looking for.. it was extremely helpful as my hair is black and I am bleaching it for the first time by myself, and I was really worried which developer I must choose .. but this video really helped me .. thankyou so much..

Mandy Hartjes: I made some calculations to get from lvl 3 to 10 in one go going off of after 50 min 10=lv6 20=lv7 30=lv8 40=lv9 Divide 50 minutes with the amount of lvls lift achieved, now you know how long 1 lvl takes multiply by 7 lvls to know the time it would take to get lvl 10 from lvl 3 40 vol equals 60 min 30 vol equals 80 min 20 vol equals 87,5 min 10 vol equals 116,66 min

Comstance Jemkins: Thank you for the content it was very helpful since I'm very New to the hair colour game

LYD VINCE CRUZ: Amazing video.Gives people and hairstylist the knowledge on what volume developer to use. Thanks for sharing.❤❤❤

kalima Tayyeba: The results with low and slow is much better. With 10 Volume it is mild to the scalp and hair, with 40 volume it burns. It is not the same pH at all. Volume 10 opens gently the keratin bonds whereas vol 40 breaks the keratin bonds because of the quick and strong push

Ladynipchick2: I would tend to favor fast and furious, but using olaplex in the mix. I wonder what your thoughts are on olaplex?

seema khalid: It's a very great experience for those who apply the colour but I like 10 vol it's mild and looking good it's easy to the hair colour

kalima Tayyeba: I would like to say that the alkaline mixture may have the same pH but the strength of pushing through the keratin layers depends on the peroxide vol. pushing quickly though keratin bonds of hair causes damage or breakage to hair strands. After 50_60 minutes we can wash hair to complete bleaching the next visit. or we can remove the mixture between fingers and put a new mixture on the same visit according to the state

Nicolas Jequier: I ALWAYS bleach with 7V or 10V and I take the hair to white with no significant damage (Latina’s, asian, doesn’t matter). I have never used 20 without really drying the hair like crazy and 30 or 40 are even out of the question

C K: I love this video!!Thanks so much.My question is I have curly hair and every time I bleach it my curl pattern suffers.Last time I went to salon I did an ombre in one sitting..but my hair suffered.Do you think I should use 20 developer in two goes??? Maybe add some conditioner too??? THANKS :)))

Tatchik77: I'm interested to know if it would be better (do less damage) to do multiple sessions of lower volume developer at recommended time or higher volume developer once?

Sarah Hernandez: In a foil thin sections I start with 10 vol and as I move up I bump the developer . I will do a partial rinse out of the bottom sections because those sections will be done by the time I’ve finished the top .

Dawn H: Good experiment. I'd like to see one regarding activator lotion and liquid lighteners, on boxed dyed dark blind ash or black dye over blond. Cheers!

Loobell: I am curious how the integrity (ignoring lift) of the hair compared from 10-40 vol with having the lightener on for the full 50 min for each...was there any significant difference? I would also love to see this same experiment done within covered foils, heat applied vs covered foils with no heat. You do great vids, sat night and life seems at a standstill, appreciate the education even with 40 yrs experience :)

M: For bleaching roots, instead of low and slow with 20 vol, would 30 vol be more appropriate? (for dark brown roots that cannot lift to pale yellow with 20 vol if left on only for an hour)

G G.: Question! With these results would you bleach again to get to platinum and then tone? Or could you tone after 1 bleaching to get to platinum? I’m a level 4 or 5, and I want to know how many times I need to bleach before I can get to platinum, as I would like to bleach only 1 time but I don’t know if that’s possible with my dark brunette hair.

Branimir Momcilov: Tnx. for great video! High volume is fine for open air. In foils higher vol. generate higher temperature. I prefer low&slow in foils, strandlights, platinum card... Saturation is also very important part.

Donna Brown: Your so right…it depends on your base but I’m a base 5 and bleach to platinum I used to do a 20 volume for 1hour with a bag my hair was broken I did 30 volume for 45 minutes with bag and toned after with both still didn’t give me a clean blonde 20 my hair pulled oranges and red and the 30 was a canary yellow…Iv now started 40 volume for 15-20 minutes without bag the last few times I rinse bleach and tone straight away to seal cuticle before I shampoo after my hair is white clean long and healthy no breakage…I don’t believe in low and slow it destroyed my hair and doesn’t get you bright enough…in and out with 40volume 20 minutes max for me the longer you leave it in your hair it’s gonna damage it…it’s taken me nearly 10 years to experimenting with bleach’s hi lifts and toners I was always terrified of 40volume and never touched it I’m so glad I did you leave it in less time blow the cuticle out and you get the cleaner lift quicker without damage

M.Saeed11: Thank you so much for your valuable time to make this video and provided us knowledge. I hope you teach us more about colouing.
