What should you know about medicated dandruff treatment?

Dandruff involves shedding of scalp skin that becomes visible as flakes. A medicated shampoo may loosen scale, reduce inflammation, or limit the yeast associated with some scalp conditions. Seborrheic dermatitis can cause more persistent flaking, redness and itch around the scalp and hairline. The right product depends on the appearance of your scalp, how sensitive it is, and whether another condition is present.

Follow the product directions for how much to use and how long it should remain on the scalp. Work it through the scalp rather than only the hair, and rinse thoroughly. Avoid scratching, picking flakes or applying several medicated products at once unless a clinician advises it. A dermatologist may recommend alternating treatments or adding a topical antifungal treatment when shampoo alone does not settle symptoms. Moisturising the scalp may help if treatment causes dryness, but choose products suitable for your scalp.

Arrange a dermatology assessment if flaking is thick, painful, bleeding, spreading beyond the scalp, or accompanied by hair loss or marked redness. Seek prompt medical help for facial swelling, breathing difficulty, widespread blistering, or a rapidly worsening reaction after applying a product.

Ask which ingredient fits your scalp, how often to use it, when improvement should be reviewed, and what to do if burning or irritation develops.
