The CG method stands for Curly Girl method and is an approach to hair care for curly textures. It was formulated by author Lorraine Massey and the general concept is to use and avoid specific hair care products. The avoid list includes sulfate-free shampoos and products containing silicone and waxes. This method is for natural hair that has not been chemically altered. The desired result is hair that is voluminous, stronger, better moisturized, and less frizzy.
