Wash your scalp with an anti-dandruff shampoo containing ketoconazole, zinc pyrithione, selenium sulfide, or salicylic acid
Leave the shampoo on the scalp for 3–5 minutes before rinsing
Gently brush out loose flakes with a fine-tooth comb
Use lukewarm water instead of hot water
Avoid scratching your scalp
Apply a small amount of diluted tea tree oil to the scalp if tolerated
Use a lightweight scalp moisturizer if dryness is causing flaking
Avoid heavy hair oils and greasy styling products
Blow-dry the scalp on a cool setting if it stays damp
Repeat anti-dandruff treatment regularly to keep flakes from returning
