Thinning eyebrows result from a variety of causes, including the natural aging process. Your hair follicles can shrink over time and produce thinner hair or stop producing any hair at all. When your brows lack the fullness you are looking for, it can also be the result of years of tweezing that may have damaged your hair follicles.

When your brows lack the fullness you are looking for, it can also be the result of years of tweezing that may have damaged your hair follicles.
Thinning brows can also be due to genetics or skin conditions like alopecia, eczema or psoriasis, or medical conditions like hypothyroidism and hormonal changes. Some medications can cause hair loss, and stress and nutritional deficiency are also suspected to cause thinning eyebrows.
