Cradle cap-like scale on an adult scalp

Cradle cap-like scale on an adult scalp is more often an adult scalp condition than infant cradle cap and deserves a clear diagnosis. Seborrheic dermatitis can cause greasy flakes, redness, and itch, while psoriasis, eczema, contact irritation, or infection can look similar. The appearance alone cannot identify the cause.

Adult seborrheic dermatitis commonly affects the scalp, hairline, eyebrows, ears, and beard area. Scale may be white, yellowish, or greasy, with variable itch. Psoriasis can create thicker, more defined plaques, and a new product can trigger contact dermatitis. Hair loss, broken hairs, tenderness, or a ring-shaped rash needs assessment because it may indicate a different scalp disorder.

Wash with a gentle cleanser and avoid scratching or lifting plaques with the nails. Pause recently introduced dyes, fragrances, oils, or styling products if irritation followed their use. Do not use a child’s treatment or a strong adult product on your own, particularly on broken skin. A dermatologist may discuss [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) or [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) after examining the scalp.

Arrange an appointment if scale persists, spreads, repeatedly returns, or interferes with sleep. Seek prompt care for pus, marked pain, swelling, rapidly worsening redness, fever, or tender areas of hair loss. A clinician may need to inspect the scalp closely and choose treatment based on whether the process is inflammatory, irritant, or infectious.

Ask which diagnosis fits the pattern, whether your shampoo or hair products could be contributing, and how to protect the hair and scalp while treating it. Mention itch, flaking beyond the scalp, hair shedding, and any previous treatment response.
