I just used this for the first time because I had a coupon for a free box. I made my hair fall out. After my shower, I put in leave in conditioner and the first brush stroke is when I saw the horror. I all my started it kink. Ever time I brushed it (detanger brush) and kinked more and more. Then I looked at my brush and saw all my hair!!!!!!! It broke off massive strands. I have hair that goes about half way down my back. Now all the front pieces are shoulder length or to my eyes. I am beyond pissed!!!! I have never had a problem with at home hair colour. Now I have to go to a hair salon and see how to get this fixed!
