I have straight, medium-length, Southeast Asian hair. I bought this shampoo and the matching conditioner because my hair easily gets oily and my scalp itches. I usually need to wash my hair every other day. Unfortunately, this shampoo and conditioner do not work at all, and are even worse than the cheap ones you can buy in any store. The hair doesn't feel clean, and when it dries, it feels rough. Not even with their conditioner does the hair become soft (neither in the shower nor when dry). My hair gets oily already within a day!!! I have liked another shampoo from this brand before, but these particular products were not good at all. I can also add that the entire box the products came in smelled very strong, and I'm not a fan of the scent. I will not buy the products again.
