Hi Matthew,

Goldwell makes several different lines of products. The ones marked "Kerasilk" in the gold bottles are the ones to look for — Kerasilk Shampoo, Kerasilk Treatment (conditioner), and Kerasilk Instant Silk Fluid (a very good, light leave-in conditioner).

I highly recommend the entire line of Kerasilk products to use on any hair system (especially the treatment conditioner). These are top-notch products. I've used dozens of different products over the years, but these beat the pants off any other shampoo, conditioner, or leave-in conditioner I've ever tried on my units hands down!

I apply the Treatment to my freshly shampooed hair by putting about a quarter sized amount in the palm of my hand, then rubbing it between my hands (like you would hair gel), then distributing it through mainly the ends of my hair (I try to keep it off the knots), then leave it to absorb for a few minutes. The longer you leave it on, the softer the hair seems to get. Rinse it out with cool water for best results... A little goes a long way.
