Sir tell me one thing please I have dandruff like from 2 years or so along with oily scalp and somewhat and sometimes bumps of painful pointy tiny things on scalp or sometime a pimple like thing. I had been using medicated shampoo and tab but wasn't consistent so never got treated and satisfied with my scalp or hair. Medicated shampoo used to dry my hair creating another havoc. Can't use a conditioner bcz hair becomes greasy. This is the current stats I use handkerchief to cover my scalp and hair while i'm outside but dermatologist says that this activity has caused folliculitis kind of thing maybe. But if I don't cover there is very bad pollution, harsh sundays and I have military hair (now after derm told to trim hair) sun rays will damage hair and scalp easily and directly. What to do I am really confused and stressed about my hair and its routine .plz help someone. please details plz.
