First of all, I have thick, course, color treated hair that had been damaged over time. It's a 10 and the leave in conditioner were recommended by the sales clerk. I Was so thankful that I went back a week later to show her how much better my hair was. After the first use I could tell a big difference in the color, texture, no more frizz everything it says it does...it does!! This product is so worth it. I get compliments on my hair everyday now. People think that I've done something to it....It just looks healthy. I love this product!!
