I've used this natural shampoo off and on for about two years now and I like it. It seems to do the trick of getting my oily hair fairly clean.However it works best only when you use it with the green tea rinse. Otherwise, it feels like your hair is not completely clean. The green tea shampoo is very thick, and I guess some of it clings on to the hair shafts and refuses to come off until you use the green tea rinse or a good regular shampoo.The only major problem is that the green tea rinse is the consistency of water and you need a fair bit of the rinse to completely rinse out your hair. As you can see, this leads to the rinse running out very quickly (think monthly) and the stuff is not cheap either. So, as a result, I don't use this shampoo very much due to the high costs of use.
