Have used multiple combinations of scalp scrubs and shampoos but I my scalp would usually go scaly again in like just 2 days. In just first wash I could notice the difference. Excess oiling reduced and so did itching. I can go back to normal shampoo schedule which is twice weekly. Bit pricy but worth it. You don't need to use a lot either. Just focus on scalp and use as instructed. Will be sticking to this product for a healthier scalp.
