Without a doubt, this is one of the best conditioners/treatments on the market. I have used this product on and off since 1992 (way back when it smelled strong and cheap, like Paco Rabane cologne). Luckily, Goldwell has removed the strong men's cologne fragrance, and it now smells soft and clean. This conditioner glides thru hair effortlessly & makes hair feel like silk (just as Goldwell claims it does). My hair is short, but I bleach and tone it silver EVERY 3 weeks! Yes, bleach and tone every 21 days!!! I have never lost one hair to breakage, and everyone (especially my stylist) is amazed how shiny, strong and reslilent my hair is. My stylist says she is blown away, that my hair still feels and looks like hair...considering how white/silver my hair is double processed to! You will love this conditioner. Btw, the Goldwell Kerasilk shampoo works great too, but I find my hair (roots) look oily by midday...and that shows how rich it is, since my hair is so processed. I use Aveda Shampure with Goldwell treatment...and my hair is awesome!!
