Worth the hype
This is easily the best shampoo I've ever tried. I've been spending money for years on high end and supermarket brands that either leave my hair too dry or too greasy. This is like my Little Red Riding Hood moment. It is just right.

Shampoo
My hair dresser recommended k18 shampoo. It does what it advertises . It makes my hair very soft and in good condition . My hair feels great after I blow dry!

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.
