I tried this shampoo to overcome oily scalp, before I used to wash my hair every other day. After 3x use, I still was my hair with the same frequency, but it feels much less oily on the second day than before. This shampoo seems to work for me. I'll order a bigger one next time. Shampoo itself foams well in my hair, very little amount is needed. Packaging is excellent with the pump. It has a smoothing effect on my hair, I only need conditioner because I have died hair.
