Straight Hair To Curly Hair!

My hair is literally straight: how can I curl it at home? I want to make sure when the barber is cutting your hair is that they texturize deep down into it, so they cut little Peaks and troughs into the hair. That'Ll then, give it a little bit more movement, put something like a sea salt spray can mousse, and then you want to get like a diffuser which will then attach onto your hair, dryer place it onto your hair and then rotate around it. And then that will be able to bring a little bit more texture and a little bit more of a wave out. It'S never going to go curly because it's if your hair is super straight. Just trying to get a little bit of texture in there will will be good for you.
