This shampoo has exceeded my expectations. It lathers so nicely and smells amazing, just like Aveda and other fancy shampoos I've tried. I have oily hair and only wash it every few days, but this leaves my scalp feeling squeaky clean without drying my scalp. I never thought I'd find a biodegradable shampoo that would compete with my fave Aveda/ Nexxus/Biolage shampoos.
