My hair has been growing sooo fast. I think it is because I have been using a clarifying shampoo every wash. This is me theory: Since your scalp is an extention of your face it needs to stay clean as well. By washing you help stimulate it but you also need to get it clean and sometimes you just can't do that with very gentle shampoos. So by using one to get build-up out you strip hair strands of excess gunk. A clean scalp = happy scalp= more growth. I combat dryness buy shampooing with a mositurizing shampoo and then using a moisturizing conditioner for 30 mintues. I was so concerned for a long time about over cleaning my hair but I recently realized that my hair wasn't doing that well because it wasn't clean. I think I finally understand what my hair likes.
