I have very thick and wavy hair so I normally don't need to shampoo every day. In fact, if I do shampoo every day my hair becomes frizzy and limp. This waterless foam shampoo is GREAT for those days in between a regular shampoo. It smells awesome and because it's a foam, there is no residue on your hair and it does not weigh your hair down. It made my hair instantly feel more fresh without feeling like I just put in a ton of product. I love it and plan to keep using, especially if it's only $5/bottle.
