One of the best conditioners I've ever used.

I use the Kerasilk shampoo as well and it has improved the condition of my hair substantially. I started using it after I got the Goldwell Kerasilk straightening treatment and it helped to extend that by a few months, I'm sure. It makes my hair so smooth and shiny; I have very thick hair that tends to get a little frizzy and this helps hydrate it beautifully.
