Why Are Your Eyebrows Thinning? 10 Causes You Need to Know

Why are your eyebrows thinning? Eyebrow hair loss, also called madarosis, can have many different causes, and finding the underlying cause is often more important than simply reaching for a brow growth serum. In this video, dermatologist Dr. Dray explains the most common causes of eyebrow thinning and eyebrow hair loss, including alopecia areata, thyroid disease, atopic dermatitis, seborrheic dermatitis, infections, nutritional deficiencies, medication side effects, trichotillomania, and trauma. She also explains why distinguishing scarring from nonscarring eyebrow hair loss is so important. One of the key conditions discussed is frontal fibrosing alopecia (FFA), a form of scarring hair loss that can cause eyebrow loss and may sometimes affect the eyebrows before obvious scalp hairline changes develop. Early recognition and treatment can be important for preserving remaining hair follicles. Dr. Dray also discusses minoxidil for eyebrows, cosmetic brow growth serums, prostaglandin analogs, and why stimulating hair growth is not the same thing as treating the underlying cause of eyebrow loss. The video covers clues that may help distinguish different causes of eyebrow thinning, including patchy eyebrow loss, loss of the outer third of the eyebrows, redness or scaling, itching, changes in the scalp hairline, and shiny or scarred skin.
