Dandruff on a bald or shaved scalp

Without hair, flakes and redness may simply be easier to see. Dry weather, frequent hot washing, harsh cleansers, shaving irritation and seborrheic dermatitis can produce overlapping appearances, so the surrounding skin and symptoms matter.

Loose white flakes with mild itch may fit dandruff, while greasy scale with redness around the scalp, eyebrows, ears or beard can accompany seborrheic dermatitis. Burning immediately after shaving or applying alcohol-based products suggests irritation.

Thick sharply bordered plaques, ring-shaped patches, pustules or areas that bleed need a closer look because they do not fit a straightforward flaky scalp. Sunburn can also cause later peeling and tenderness on an uncovered head.

Wash with lukewarm water and a gentle cleanser, then use a fragrance-free moisturiser if the scalp feels tight. A medicated dandruff wash can be applied directly to scalp skin according to its label; rinsing too quickly may reduce contact with the affected surface.

Pause close shaving across sore or inflamed areas, clean clipper heads and avoid scratching off adherent scale. Protect an exposed scalp outdoors with shade, a comfortable hat and sunscreen suitable for your skin.

Consult a clinician if regular scalp care does not settle the flaking, or if redness extends to the face, ears or neck. Review is also appropriate for recurring crusts, painful bumps or uncertainty about which medicated product suits the pattern.

Get prompt care when the scalp becomes hot, swollen or increasingly painful, when pus appears, or when fever accompanies spreading redness. A changing pigmented spot, persistent sore or area that repeatedly bleeds should be examined rather than treated as dandruff.

Ask whether the scale resembles dandruff, seborrheic dermatitis, psoriasis, infection or irritation, and how often to use any prescribed wash. Mention shaving products, recent sunburn and flakes elsewhere on the body.
