I've tried a few CoWashes, and I always come back to this one. It's hands-down the best one I've used on my natural 4a/4b hair. It not only does an excellent job of cleansing my hair and scalp but it defines my curls/coils very nicely and reduces almost all frizz (as long as I don't manipulate my hair too much after washing). The shampoo/conditioner combo just ruins my curl pattern but this does just the opposite! I love it.
Plus, the container is a great size and lasts for quite awhile. It can be a pain to scoop it out in the shower, but it's worth it since it's so effective. Even my husband likes this. He tried it once and he was using it several times a week in the shower and used up most of it.
It smells sweet, like coconut, and has a nice, creamy texture. It doesn't lather (since it's a cowash), but rest assured, it's doing a better job than any lather could!
