I have a problem, my hair grows super fast but not a lot. I have very little hair at the center of my head and I heard that exfoliating shampoos help clean out your hair pores (I think that's a thing) and it'll help with hair grown. Is that true? And if so,do you recommend this Briogeo Scalp Revival Charcoal + Coconut Oil Micro-Exfoliating Shampoo. ?
