Very impressed with this shampoo. It is surprisingly gentle for an “exfoliating” shampoo. The star anise is hydrating and I have noticed a distinct difference in my scalp health since starting to use this product every other day (along with the hydration conditioner and scalp treatment). The only thing I will say about this shampoo compared to others by Rahua is that it does need to be shaken and it is a bit runny, so I go slow and add more as needed. I live in New England where the water is hard and the winters are harsh. I’ve never experienced the need for focused scalp health support, but this climate has done it and I knew exactly where to go… Rahua!!! And, as always, you all have provided an excellent product.
