i have a similar problem. the skin itches at
scalp as soon as it starts sweating a little. that
means if i step into the sun for a minute, it starts to itch really bad. and i can feel the flakes sticking to the roots of a10-12 hair, holding them together. it is as if it was a wet flaky paste that settled there and then dried up. i have to scratch it away really hard to get it off the scalp. also, the hairline is receding and the redness is evident in all the scalp wherever i scratch it.
