Spots on the head when you have alopecia

Where lesions occur is useful: spots confined to the scalp suggest a different set of triggers from a rash extending over the hairline, forehead, cheeks or around the mouth. Surface features and hair changes also help narrow the cause.

Folliculitis can present with bumps or pustules arising around scalp hairs. Acne presents with clogged pores and inflamed lesions, often in oil-prone areas. Razor bumps can appear where hair is cut closely. A facial eruption around the mouth or central face may require evaluation for conditions such as perioral dermatitis or rosacea rather than being treated as scalp acne.

Hair loss needs its own description. Observe whether the spots sit inside an area of missing hair, along its edge or elsewhere on the head. Smooth skin, broken hairs, scale, crust, scarring and loss of follicle openings are clinically meaningful differences.

Use a mirror or ask someone to check areas that are hard to see. Record the distribution with clear photographs and note itch, pain, discharge, flaking and recent spread. Cleanse gently, avoid scratching or squeezing, and pause new dyes, oils, sprays or adhesives if symptoms began after their use.

Do not apply a facial steroid, acne treatment or antibiotic left from an earlier problem without guidance. These products can alter the eruption or irritate sensitive scalp skin. A clinician can examine follicle openings and decide whether a skin scraping, swab or other targeted check is useful.

Seek prompt care when spots are accompanied by fever, rapidly increasing swelling, severe tenderness, spreading redness, blisters or substantial pus. Schedule an assessment for persistent crusting, bleeding, scarring, a rash spreading beyond the scalp, or hair loss that is new, enlarging or associated with broken hairs.

Ask whether the distribution supports a follicle problem, contact reaction or facial skin condition, and whether the alopecia shows inflammation or scarring. Clarify which scalp products to stop, what signs should trigger earlier follow-up, and whether treatment could affect hair growth or colour-treated hair.
