Rated 1 out of 5 by from not what I expected I really thought this would be great… but this was very drying for my scalp… I invested in the 33.8 ounces and even after using the conditioner I still felt dry scalp was an issue! I do not like this product!

Rated 5 out of 5 by from Fuller Hair Without the Heavy Feel I have fine, color treated hair and most thickening shampoos leave my hair feeling heavy or sticky. This one made my hair feel fuller while still staying soft, clean, and lightweight. It smells great, rinses well, and honestly surprised me in the best way.
