I have dandruff and sometimes I feel my head really itchy, with pale flakes. I use this after I take a bath and it helps me a lot controlling the flakes and the itching sensation. It has a really low pH, really good for control the sebum secretion. I bought it in October, 2017 and I have enough tonic yet (now in March 2018). If you want something really soft with your scalp, you must give a chance to this product.
