I previously used chi silk infusion when straightening my hair. When I ran out, I wanted to find a cheaper product that gave similar or better results. That's when I found out about this stuff from a friend. It is AMAZING! I am transitioning from relaxers, I am about half natural and half relaxed. I have a Sedu revolution flat iron also. I put some of this on my wet hair and plaited my hair to dry. When it was dry I put a little more on and flat ironed. I loved the results as I was doing it and even more after! My hair was soft, silky, shiny, and beautiful! It had a salon straightened look. I couldn't be happier with the product. I was skeptical about only paying $4 for a heat protectant, but I am glad that I did versus spending $25+ for chi silk infusion!! It proves that you don't always have to choose the most expensive product for great results. Give it a try, the price allows that. I will continue to buy the product!
