Rated 4 out of 5 by from Wishful thinking, great aid! Overall good feeling. Enjoy the smell... The real test will be to see how well it protects coloring after the perm damage

Rated 5 out of 5 by from Matrix Instacure Matrix Instacure I love this product 80% of my clientele use it. It is amazing for many different reasons. It is great for porosity strengthening thermal protectant from heat and sun detangling solution,leaves hair shiny and doesn't weigh it down. Everything now is made with protein and people's hair can get overprotonized and damaged. I have been using this product 30 years or more!

Rated 5 out of 5 by from Game Changer So I ran out of my personal conditioner in the shower, and I didn’t realize until I of course already washed my hair, so none the less I just shampooed and hoped for the best after I put this in my hair damp. My hair dried SO SOFT. I can’t even imagine how good the hair will feel with using conditioner or a conditioning treatment before this. Amazing!
