What should you know about oily dandruff?

Oily dandruff often produces flakes that look white to yellow and may cling to the scalp or hair. It can come with itch, greasy scale, or mild redness. [Seborrheic Dermatitis](/conditions/seborrheic-dermatitis/) is a related inflammatory condition that may affect the scalp and other oily areas. Flaking can also reflect irritation, psoriasis, or another cause, so appearance alone cannot confirm the diagnosis. You can compare symptoms with [Itchy Scalp](/symptoms/itchy-scalp/) and [Flaky Scalp](/symptoms/scalp-flaking/).

Wash the scalp regularly with a gentle cleanser and avoid scratching or lifting scale with your nails. For persistent dandruff, a clinician or pharmacist may recommend [Medicated Shampoo Treatment](/treatments/medical-dermatology/medicated-shampoo-therapy/) or [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/). Use the product exactly as directed, including any recommended contact time, and stop if severe irritation develops. Rinse thoroughly, keep hair tools clean, and avoid heavy scalp oils if they increase residue. Give one approach enough time to assess before layering several new products.

See a dermatologist for thick scale, bleeding, painful areas, pus, marked redness, hair loss in patches, or symptoms that spread to the ears, face, or eyelids. Seek prompt care for fever, rapidly worsening swelling, or blistering. Arrange review when flaking returns quickly after treatment or keeps disturbing sleep.

Is this dandruff, seborrheic dermatitis, psoriasis, or contact irritation? Which active ingredient should I try? How often should I wash, and how long should the treatment remain on my scalp?
