Doesn’t do much, the mint hair syrup is so much better 

My favourite shampoo right now, my scalp gets really itchy and this seems to be the only shampoo that doesn't make it worse

My scalp has been quite sensitive recently and this shampoo doesn’t irritate it. 

I get this shampoo for my husband, he finds it good at calming his sensitive scalp. 

This was bought as a gift for my mum. After trialing various treatments for dry scalp and being a psoriasis sufferer, nothing worked, but this one did. It calmed and softened the skin on her scalp and she didn't receive any irrigation at all. Winner
