My hair is dry, and my 2b curls are always brushed into 2a. I wouldn't brush them, but the girls at my school make fun if me when my hair isn't brushed thouroughly. I want to make my waves seem more like curls, and at the same time keep them healthy and moisturized. I use sulfate-free shampoo and silicone free conditioner. What can I do to enhance the curls and make my hair better in general?
