I have dermatits. But on my sclap it feels like something crawling or pulling on my sclap or hair. What should I do?

Scalp sensation. May just be due to dermatitis, but have friend/family (wearing gloves) meticulously comb through all hair to check for lice (nits/eggs on hairshafts). If found, use otc preps according to directions. Otherwise, try head&shoulders dandruff formula or selsun blue. If no improvement after couple uses, see fp for exam.
