What should you know about thinning brows?

Over-plucking, waxing, threading, rubbing, or cosmetic irritation can reduce the visible brow. Patchy loss with otherwise normal skin may occur with alopecia areata. Loss that begins near the outer brow, affects the hairline, or leaves the skin looking shiny or scar-like can be a sign of frontal fibrosing alopecia, which can cause lasting follicle injury. Eyelid inflammation and other skin conditions may also affect brow hairs.

Tell the clinician when the change began, whether it is equal on both sides, and whether scalp or eyelash hair is also thinning. Do not assume that age or grooming alone explains a new pattern.

Pause plucking, waxing, and irritating products while the cause is being clarified. Cleanse gently, avoid rubbing the area, and photograph both brows from the same distance over time. A clinician can inspect the follicles and surrounding skin and decide whether further testing or treatment is appropriate. Cosmetic pencils or powders may camouflage gaps without pulling the hairs.

Book an assessment if loss is sudden, progressive, asymmetric, associated with redness or scale, or accompanied by scalp, eyelash, or hairline changes. Seek more prompt advice when the skin becomes painful, crusted, shiny, or scar-like. Early evaluation matters when follicle damage is possible.

Ask which features distinguish grooming-related loss from alopecia areata or frontal fibrosing alopecia, whether any products should be stopped, and whether the follicles appear active. Ask about safe cosmetic camouflage and the timeframe for reassessment.
