After trying many anti-dandruff shampoos, both supermarket, pharmacy and iHerb, this is the one I like. I control very well the issue of desquamation (except in times of more stress, which is irremediable) although I quite dry hair, so it is essential to use a good conditioner or mask later. I personally like it better than Jason, as it is more fluid and easier to spread. I do not bring fat and I just need to wash my hair 2 times a week, despite normal-fat have it. I'm on my second boat and repeat indefinitely!
