What should you know about eyebrow hair falling out?

Loss can be diffuse, patchy, or limited to the inner, middle, or outer brow. Smooth patches without scale may fit alopecia areata, while itch, flaking, redness, or broken hairs may point toward an inflammatory or infectious process such as scalp ringworm. Repeated pulling from tweezing, waxing, threading, or tight styling can cause traction alopecia. Hair-cycle shedding can follow a significant illness or body stress. These patterns overlap, so appearance alone cannot establish the cause.

Stop pulling and avoid new brow products while you observe the area. Wash gently, do not scratch scale, and photograph the brows and scalp in similar lighting. Note the start date, recent illness, stress, diet changes, medicines, and whether eyelashes or scalp hair are changing too. A dermatology visit can include inspection of the skin and follicles and may lead to targeted testing or treatment. See [Alopecia Areata](/conditions/alopecia-areata/), [Traction Alopecia](/conditions/traction-alopecia/), and [Hair Loss](/symptoms/hair-loss/) for related information.

Arrange care if the loss persists, progresses, or forms a clear patch, especially with itching, scale, tenderness, redness, crusting, or pus. Seek prompt medical help for marked swelling around the eye, severe pain, or vision changes. Review is also sensible when eyebrow loss occurs alongside new scalp patches, nail changes, or unexplained symptoms elsewhere.

Ask whether the hairs are shedding from the root or breaking, what pattern the examination shows, and whether your scalp or eyelashes should be checked. Ask which habits or products to pause, whether testing is needed, and how progress will be monitored.
