rachel i think tht the washing routine and the stress is right about psoriasis but i can't imagine making a 10% salicylic acid with mineral oil on my scalp. i used to use the neutrogena salicylic acid shampoo and this made my head sore. right now i am using a shampoo without sls in it and it seems to have controled my scales on my scalp. i wash in warm water not hot and use a netting scrubber to smoothe away my scales on my back. i use dial yogart/vanilla and honey body wash. it helps keep my back from drying out so much. then i apply rosehips and hibiscus cream. this is not getting rid of my psoriasis but it is controling it.
