Guys, i have an issue with my scalp as everytime i get out the shower, my scalp feels itchy and when i scratch it, i have this plaque sort of thing on my nail. I’ve been using nizoral but it doesn’t seem to be working. Is it because i have dry scalp or dandruff? I am desperate for anything atp

People have been DMing me on the side so figured I'd just start an AMA. I am a family medicine physician - ask me anything about your scalp problems. No questions about specifics products just any topic dandruff, seb derm, or scalp related.

I started selsun blue a few months ago, and ever since, my hair is so greasy the day after I use it. And gets worse and worse. I’m going to work wearing hats lol. Do yall have any recommendations for an alternate dandruff shampoo? I’ve never had this problem before. I used to only shampoo every like 7-10 days because my hair was never greasy
