psoriasis
"This was prescribed to me for scalp psoriasis after trying a medical shampoo and another topical lotion with no relief from the itch and flakes. I found within the first few applications it relieved the itch and got rid of about 90% of the plaques on my scalp. I have been using it for almost a month now and its made a worlds difference for me! 
The only reason I've not given it a 10/10 is how greasy it is, its hard to apply and much harder to remove from my hair. 
After trying a couple of things I've found that the trick is to use baby oil to break down the stickiness and use dish soap to wash it out (I do this step at night before bed) then in the morning I use Loreal's extraordinary clay hair mask to absorb the remaining baby oil!"
