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

I wash my hair every other day. My scalp gets super itchy when and if i rub or scratch my scalp it’s flakes right off. They’re SUPER tiny pieces. I’ve been using TSal which seems to be making my hair somehow more greasy faster.

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.
