Ummm…helps scalp but not hair?! I have experienced less flakes using this shampoo but it consistently leaves my hair feeling grimey—like oily/dirty immediately after drying. Even with thorough rinsing my hair feels like it has a layer of something left on it. I wouldn’t buy this again and the way I am using it up is by mixing it with a different cleansing shampoo to help get my hair clean…
