I honestly didn't expect this anti dandruff shampoo would help with my occasional boots of dry scalp but I was tempted to try ,so I did and I saw and felt a difference after one use ! Not only that ,it made my hair quite shiny and smelling fresh . I've used the other variants in the range and this one is by far the best. I would however use it every now and then because in my experience prolonged use is drying to my hair.
