Yes it definitely adequately cleanses mine. I have using the Shea Moisture Purification Mask and when I rinse I always get soft yet cleansed hair strands and a happy scalp. It has kaolin clay in it. I use it once a week and cowash in between when need to.
I'm going to get some Rhassoul clay to cleanse with it as well. Mind you I don't use a lot of stuff on my hair weekly so shampoo was really drying it out even though it was once weekly.
I LOVE the purification mask for cleansing my hair but it doesn't seem to get that oily buildup off my scalp. I may try leaving it on longer and massaging a bit harder. Thanks for your input!
