To me they are
I've tried
Green Tea - Clarifying
Jojoba, Aloe - Moisturizing
Evening Primrose - Sensitive Scalp
Calaguala Fern - Sensitive / Oily
They all dried my scalp and made it sore
BUT I've never prepoo'ed first
I think one reason is because their conditioners
although I love them do leave behind a waxy buildup
and they're designed to use BEFORE shampooing
so maybe the shampoo is tough to make sure it will
remove the build up
I would blame the ingredient Coconut Oil-Corn Oil Soap maybe it bothers people although it seems like it would be moisturizing
