It's a mild shampoo and definitely relieves the itchiness and flakiness the first 1-2 days after any wash. It also doesn't have any strong scent, so it's easy to use on a daily basis. However, this is not a long-lasting cure if you have the more persistent types of dandruff, flaky or itchy scalp, or oily hair.
I have a very oily and itchy scalp, along with very bad dandruff. I have tried everything, from over the counter products to clinical treatments. So, I had no expectations. It was just another new product I was trying. Boy was I surprised, by far it's the best product I have ever used. I know strong statement, but it reduced my flaky dandruff too next to nothing in just two washes. Only downside is the price point for the quantity you get. But for this kind of results, it's worth it.
I can feel the difference after using this product.
