Could anyone tell me how you can fix your hair with a roller brush and hair dryer?

I really don't know how to explain it but usually after you get your hair cut the person who cuts it will use a roller brush and hair dryer to dry it out. It has like a flip to it. I really would like to achieve that hair style but every time i try i end up messing up. How do you do it?





and could you also tell me what products you use?Could anyone tell me how you can fix your hair with a roller brush and hair dryer?
I tried it last time I got my hair cut. It didn't really work. I think it's impossible. Haha. It might just because 1. They can reach the back of your head better. 2. They are professional. (I hope) and 3. I feel like only having two hands is a problem.





Try blow drying it straight first and then use the roller brush in sections. Good luck!
