Maybe you're sort of right. I do have an oily scalp. My doctor had me use generic loprox shampoo every other day for a month and take 100 mg doxycycline. The bumps cleared up completely. I used head and shoulders in between and I think it may have made my scalp dry. Now, I use whatever shampoo I want. It's been a couple of weeks and no bumps. The doctor said to use the loprox shampoo once a week but I don't know if and when I can stop using it completely. My advice for anyone is to see a dermatologist if you can. I'm thankful that I don't have to worry about nasty bumps on my scalp at least for now...
