After purchasing a small bottle of this at a salon, I was skeptical. I am over 50 and have long thick dry curly hair that always looks frizzy after washing. When I put on a few drops of this after washing and conditioning, I was happy that it worked! Now, I want to find more to buy, because it has become my go-to product that I cannot live without. I now have the curly look I've wanted without having my hair look dry or coarse or flat.
