Thanks for posting a link to the study.. very interesting and surprising to read. I have not had a transplant as yet.. I'm probably going to wait until 35... Funnily enough, although I still have some small areas of dryness on my scalp, the psoriasis plaques around my hairline cleared up completely without any treatment around 6 months ago and haven't returned which is great! I do still have it on some other body areas though, albeit quite mild.
