I also found Joico products very good on my scalp, it was actually my hairdresser who told me to try it years ago. I was very skeptical as I had been using prescription shampoo, lotion etc but it definitely helped and treated my scalp much better!

I was prescribed Diprosalic lotion for mine by the GP, which goes on like water and you rub in and can't see or notice it - have you tried this? I was using Neutragena shampoo for 3 or so years which I thought would be best, but then switched to Joico unmedicated ordinary shampoo and condition (which is in a green bottle) and which you can buy online. I have been using this for 3 months now and my scalp has improved loads.
