This shampoo is great! My husband has severe case of seborrhea dermatitis and usually his scalp reacts very bad with regular shampoo's. So far nothing worked for long enough until he tried this one! He's using it every day, and a bottle can last really long (for men at least). It has creamy texture, and not parfumed smell, but nice and clean. He's been using it for very long time now (over a year) and he doesn't get any flakes or dandruff at all, it's totally miraculous! It's worth the money, and it's totally natural, so therefore the best option! Seriously, the best miracle worker for very sensitive scalps!!
