Best shampoo on the market
I pair this up with the conditioner and also the detox once a week and consistently rave about these products. You cannot go wrong with K18.

Gentle and effective
I have fine hair and a sensitive scalp, so I tried this with caution. It cleans beautifully without stripping or irritating my scalp. My hair looks revived, feels better, moves better. This is a great product.
