What should you know about greasy hair and dandruff?

Oiliness is a feature of the scalp, whereas dandruff describes flaking. They can appear together without meaning that hair is dirty or that poor hygiene caused the problem. Seborrheic dermatitis may produce greasy scale with redness around the hairline or behind the ears. Itch, burning, thick plaques, sores, or hair loss point toward a need for closer assessment. Hair products can also leave a film that looks like flakes, especially when several products are layered.

Choose a gentle shampoo and wash as often as needed to keep the scalp comfortable; focus the lather on the roots and rinse fully. A medicated shampoo may reduce flaking when used as directed. Avoid scratching, tight hairstyles, and heavy oils on the scalp while it is irritated. If symptoms do not improve, a clinician may recommend topical antifungal treatment after checking whether inflammation or another condition is involved.

Arrange care if dandruff persists despite a consistent routine, keeps returning, or spreads to the face or ears. Seek prompt medical attention for pus, painful bumps, fever, spreading redness, bleeding, or sudden patchy hair loss. A scalp examination can separate dandruff from psoriasis, infection, or contact irritation.

Could my products be irritating the scalp? Which medicated shampoo should I use? Is topical antifungal treatment suitable, and how can I prevent flare-ups?
