What should you know about greasy dandruff scalp?

Dandruff is scalp flaking that may be white, yellowish, or greasy. Seborrheic dermatitis is a related inflammatory condition that can make scale stick to the scalp and may affect the hairline, ears, eyebrows, or sides of the nose. Itch is common, but severe pain, pus, thick plaques, or broken hairs suggest that another problem may be present. Greasy flakes do not reveal the cause by themselves; a clinician may inspect the scalp and ask about products, washing habits, and symptoms elsewhere.

Use a gentle shampoo regularly and massage the scalp lightly with fingertips. A medicated shampoo may help loosen scale and control the process driving dandruff; follow its label or clinician instructions and rinse thoroughly. Avoid scraping flakes off, applying undiluted essential oils, or layering multiple irritating products. If the scalp is very inflamed or keeps relapsing, a clinician may consider a topical antifungal treatment or another medicine suited to the examination findings.

Seek dermatology advice when flaking does not settle with consistent care, spreads beyond the scalp, or causes significant redness or itch. Get prompt help for painful swelling, pus, fever, extensive crusting, or sudden patchy hair loss. A child with heavy scaling or broken hairs should be assessed rather than treated with repeated over-the-counter products.

Is this straightforward dandruff or seborrheic dermatitis? How should I use a medicated shampoo? Would a topical antifungal treatment help, and what should I do if the flakes return?
