i use to have dandruff also, but i already get rid of it. i don’t exactly know which worked for me but i’m just going to share some hair care tips.
-applying argan oil at the ends of my hair (helps in dryness)
-using shampoo every after 3 days
-conditioner everyday (but only at the end part of the hair, i try my best to avoid applying it in the scalp)
-if the weather is gloomy i don’t wash my hair at all
-using hair clamps
