Well my first guess is that this would work extremely well for caucasian women. (i'm speaking theoretically) Or for women who haven't permenantly damaged their hair with a chemical of any sort. The reason being is that their hair isn't damaged, it's in it's natural state, it's healthy and is properly oiled. So rinsing the hair daily of impurities such as dust, lint, excessive oil, or smoke would work. However, if your hair is chemically treated, which means the cuticle has been degraded to some degree....i'd highly advise to continue to use at least a conditioner to keep your hair's cuticle sealed, to temporarily add protein to strenthen, and also to moisturize and lubricate your hair. This is important to retaining your hair strands. Like i said...if u ain't got chemical damage, then rinsing probably would be good enough to remove dirt. Our hair actually dries so very quickly if it doesn't have any products in it. (I tried it a few months ago and was pleasantly surprised) It dries so fast that your hair doesn't have the time to 'frizz up'...so your hair dries straight(er). surprise, surprise.... I guess it makes sense cause a moisturizer is supposed to help retain moisture in your hair ....
