I've suffered from scalp psoriasis for 10 years and was having a particularly bad flare up recently which was becoming unbearable. I've tried every product out there to relieve my symptoms over the years and not had much joy. But now I can't begin to describe my relief at finding Oregon. I've been using it every 2/3 days for the past 4 weeks, allowing my hair to dry naturally and not using any styling products to give Oregon the best chance of working. Not much changed at the start, but after 10 days or so, i began to notice the scales and flaking becoming easier, which in turn reduced the itching. My scalp is so much calmer now. I even had my first day in 10 years where i didn't scratch it once! The smell is a little like a bonfire but it eases off and it's well worth putting up with! I'll be sticking with Oregon from now on! It's a life changer for me!
