What do you suggest if i have dandruff selenium sulfide treatment problems?

Anti-dandruff 'poos: Dandruff is associated with malassezia fungus infection. Try other over-the-counter dandruff shampoos, and look for one that contains zinc pyrithione, which can reduce the fungus; salicylic acid, which works as a sort of scrub to slough off dead skin; or ketoconazole, which works against a broad array of fungi. See a Dermatologist if these don't work. Take care.
