Non-scarring alopecia areata: what to know

Alopecia areata often appears as one or more smooth bald patches on the scalp or beard area. The skin may look normal, and short tapered hairs or small broken hairs can occur at the edge. It can also affect eyebrows, eyelashes, or body hair. Because the follicles are not replaced by scar tissue, this pattern differs from scarring alopecia.

Hair loss can change over time, and the emotional impact may be substantial. A clinician may inspect the scalp and nails, ask about other symptoms, and use dermoscopy or testing when another cause is possible. Do not blame yourself or assume stress is the only explanation.

Arrange a dermatology assessment for new bald patches, rapid spread, eyebrow loss, scalp symptoms, or repeated episodes. Take gentle care of exposed skin, use sun protection on bare areas, and avoid tight hairstyles, scratching, and harsh chemical treatments. A doctor may discuss observation, topical treatment, or steroid injection into the skin depending on the pattern and extent.

Take clear photographs in consistent light if you want to track change. Tell the clinician about family history, nail changes, thyroid symptoms, medicines, and any loss elsewhere. Treatment choices should match the diagnosis rather than the appearance alone.

Seek prompt assessment when hair loss is sudden and extensive, the scalp is painful or scaly, the skin looks shiny, or follicles seem absent. These features can point toward another type of alopecia, including a scarring condition, where early treatment may help protect remaining follicles. Seek urgent help for facial swelling or breathing difficulty after a treatment.

Ask: Does the pattern look like alopecia areata? Are the follicles still intact? Do I need tests or a biopsy? What are the benefits and risks of steroid injection into the skin? How will we monitor regrowth or spread?
