Think what caused it is a shampoo I used for about a week before stopping. Stopped and cut my hair short and seems mostly fine but some areas still have white bits (dandruff, dry skin, not sure) that usually has loose/dead hair with it. I can't tell what I have if it's dandruff, fungal, hair loss or the title. Don't think my hair is thinning but this could be early stages, I'm 22...

This may be a coincidence but since then I have had flies attracted to me and swarming me, even when not sweaty. PLEASE ADVISE
