Oh, I can sympathise. I have a very stubborn patch of psoriasis on my scalp which drives me up the wall. In the last 3 1/2 yrs I think I managed to be free of it for about 6 months, I've tried just about everything on the market, to no avail. I'm now convinced that my hair is thinning on the top and crown, though at the hd yesterday she didn't see any difference. I was at the hd to get my greys done - they're not particularly resistant, my hair just grows too quickly and I have roots showing about 10 days after tinting. My hair feels like straw today, it rained this a.m. so I'm a big frizz ball and just feel hideous. I'm also growing out a fringe, still not convinced it's a good idea, especially given the wrinkles on my forehead. I'm going "home" to the uk next month, seeing family and friends and feel so bad, it's not funny. So, hugs coming your way, I know how you feel!
