I have had these recurring bumps on my scalp that often get worse at certain times of the month but are always there. They are mostly at the top of my scalp and behind my ears. My scalp is itchy and dry and itches mostly at night. I have tried prescription shampoos for eczema, dermatitis and most recently tried a foam called clobetasol. I have also tried many over the counter shampoos, lotions, etc. While some have provided relief for the itching nothing has taken the bumps away or alleviated the problem completely. This has been going on for years now.
