I have been using the shampoo and treatment lotion for several months now. I suffer from mild scalp psoriasis which has really flared up since moving to London. The shampoo is really nice, keeps my very frizzy hair moisturised whilst soothing my scalp. The lotion is incredible. I sometimes have painful and extremely itchy scabs. As soon as I apply the lotion the itchiness stops and after a couple of days the scabs are healed. This is by far the most effective and pleasant product I have ever used for my scalp psoriasis. I carry it in my handbag! Use a little bit at a time and it doesn’t show or make your hair look greasy. I won’t stop using this!
