Dry flaky skin on a bald head: what to know

A shaved or naturally bald scalp has little hair to shield it from sun, wind, dry air, sweat, and product residue. These exposures can leave the surface tight, rough, itchy, or powdery. Flaking can also occur with eczema, psoriasis, or contact irritation from shaving products, fragrances, or styling products. Asteatotic eczema tends to feel very dry and cracked, while psoriasis may form thicker, more defined scale. The appearance alone cannot identify the cause.

Wash with lukewarm water and a mild, fragrance-free cleanser, using fingertips rather than nails. Pat dry and apply a bland moisturiser while the skin is still slightly damp; an emollient can help reduce water loss. Pause new scalp products and avoid picking or vigorous scrubbing. Protect the exposed scalp from direct sun with a hat or suitable sunscreen, and take care after shaving by using a clean razor and non-fragranced product. If symptoms continue, a clinician can examine the scale and tailor treatment.

Arrange a dermatology assessment if scaling persists despite gentle care, repeatedly returns, becomes thick, or extends beyond the scalp. Seek prompt medical attention for spreading redness, warmth, swelling, pus, marked tenderness, fever, bleeding, or a sore that does not heal. Sudden swelling around the eyes or breathing difficulty needs emergency help.

Could this be eczema, psoriasis, contact irritation, or another scalp condition? Which moisturiser is suitable for an exposed scalp? Should I change my shaving or sun-protection routine? What changes would mean I need a follow-up visit?
