Questions & Answers

Q: What causes thinning eyebrows, and what treatments can help?

Common causes include aging, low thyroid hormone, eczema, repeated plucking or waxing, low iron stores, zinc deficiency, and inflammatory conditions such as lichen planopilaris. Treatment starts with identifying and correcting the cause; minoxidil, Latisse, makeup, microblading, or eyebrow tattooing may also improve eyebrow density or appearance.

Q: What is the first step in addressing thinning eyebrows?

See a healthcare provider to determine the underlying cause, and consult a dermatologist if needed. Basic blood work may be used to check thyroid hormone levels or nutritional deficiencies.

Q: Can aging naturally make eyebrows thinner?

Yes. Just as scalp hair can thin with age, eyebrow hair can lose density and become thinner or patchier as part of age-related change.

Q: Can hypothyroidism cause eyebrow thinning?

Yes. Low thyroid hormone can produce thinning eyebrows as a skin manifestation, so a healthcare provider may check thyroid levels with blood work. A diagnosed thyroid deficiency needs to be treated.

Q: How does eczema affect the eyebrows?

Eczema, also called atopic dermatitis, can cause thinning of the lateral third of the eyebrow, known as Hertog sign. Chronic inflammation around the follicle contributes to the thinning, and irritating products used near sensitive eyebrow skin can make it worse.

Q: Can plucking, waxing, or threading permanently thin eyebrows?

Repeated plucking, waxing, threading, sugaring, and similar grooming can traumatize and eventually scar eyebrow follicles through traction alopecia. Once a follicle has scarred, the hair cannot be brought back, so reducing or stopping these practices may lower the risk.

Q: Can nutritional deficiencies cause thinning eyebrows?

Low iron stores, including low ferritin, can be associated with eyebrow thinning even without iron-deficiency anemia. Zinc deficiency can also cause it, although the transcript describes this as very rare in developed countries; correcting a confirmed deficiency should allow the hair to regrow slowly.

Q: What eyebrow changes may indicate frontal fibrosing alopecia?

Thinning eyebrows together with scarring hair loss around the frontal hairline may indicate frontal fibrosing alopecia, a variant of lichen planopilaris. It is seen most commonly in postmenopausal women, although it can also occur before menopause, and the follicular scarring can cause permanent hair loss.

Summary & Key Takeaways

• Thinning eyebrows are primarily due to age-related changes and the natural thinning of hair on the body, including eyebrows.

• Other causes of thinning eyebrows include low thyroid hormone levels and conditions like eczema that cause chronic inflammation.

• Grooming practices, such as plucking or waxing, can lead to hair follicle damage and thinning of the eyebrows.
