What should you know about eyebrow hair loss alopecia?

Loss can affect one brow, both brows, the inner or outer portions, or small sharply defined patches. Smooth bare areas may suggest a different process from loss with scale, redness, broken hairs, or shiny skin. Alopecia Areata can affect brows as well as scalp hair and may appear in patches. Frontal Fibrosing Alopecia can involve the front hairline and eyebrows and may leave scarring. These patterns overlap, so appearance alone cannot confirm a diagnosis.

Take clear photographs in consistent lighting and note when the shedding began, whether it is spreading, and whether scalp or facial hair is changing. Avoid plucking, harsh dyes, irritating oils, and repeated rubbing until the skin has been assessed. A clinician may examine the brows and scalp closely and ask about medicines, autoimmune symptoms, skin inflammation, and family history. Treatment depends on the cause; replacing hair before active inflammation is controlled may not address the problem.

Book a dermatology assessment when eyebrow loss is new, progressing, patchy, or accompanied by itching, pain, scale, redness, or a receding hairline. Seek earlier care if the skin looks shiny or scarred, eyelashes are also thinning, or vision is affected by eyelid inflammation. Urgent help is appropriate for facial swelling, severe pain, fever, or a rapidly worsening rash.

Does the pattern look scarring or non-scarring? Should my scalp, eyelashes, or skin be checked? Could Alopecia Areata or Frontal Fibrosing Alopecia fit the findings? What should I stop using on the brows?
