First shampoo I’ve tried that cleans my hair well and doesn’t leave any buildup. It also doesn’t trigger the psoriasis on my scalp and leaves my hair less dry than most clarifying shampoos I’ve used prior.

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.
