This shampoo worked well at just generally cleansing the scalp and hair. I wouldn't consider it a heavy duty clarifying shampoo. If you're someone with intense build-up, you would be better off trying something else.
It did lather well, because it contains sulfates. It claims to be "subtly scented," but the scent was intense.
Overall, I'd say it works well for someone with an oily scalp or someone who uses a lot of hairspray, gel, or other products which can buildup on the hair shaft and scalp.
