Your hair starts to feel cleaner and fresher from the first time you use it. This hair soap is definitely unique, natural, and shinier. However, if you're using hair oil, you'd have to re-apply this soap like 2 or 3 more times in order to remove all the oil from your hair. Anyways, this is my third day using this hair soap and I'm slightly starting to notice a difference. Oh, by the way: it contributes to hair growth ;-).
