I just bought a salicylate shampoo for my psoriasis in my scalp (just found out that was what it was, and its my first try with the shampoo).It says to shampoo and let stand for a while before rinsing - every 3-4 days.
There was another one, nizoral (much more expensive),
that was not a salicylate compound.
I asked the pharmacist and he couldn't advise me other than
to try it out, if it didn't work - buy the others - one, by one.
I must've stood in that drug store aisle for 20 mins looking at all the different choices....and I went and chose that one.....
(store brand, equal to a name brand- economics 101 !?!)
Hmmm.... ??
