Caused hair loss

Loved the texture it left my hair with, but it ended up causing a lot of hair loss and was too late to return.

Amazing but not for weekly use

This is one of the best clarifying shampoo that I’ve used. I use this every third wash (I wouldn’t recommend using any more than this as it can make your scalp dry and strip your hair of its natural oils), and I can really see the benefit to my scalp health and my hair just feeling cleaner.
