I’ve been using this shampoo for a week+, it’s good but I’m still not sure it is solving my itch issue, I’ll give it more time. What I do like is that it does not dry your hair out. I have thin grey hair, most shampoos do not leave my hair feel moist enough to comb, this shampoo holds on to the moisture, doesn’t strip my hair of all the moisture. Laters nice, I will continue using it but not sure yet, if I would buy it again. I will recommend trying it to see if it works for you at relieving itching.
