Facial Changes That May Indicate Health Issues

Certain facial changes can signal underlying health conditions.

For instance, thinning eyebrows may be more than just a cosmetic issue. According to Livestrong.com, hypothyroidism—an underactive thyroid—can cause general hair thinning, including eyebrows.

Another cause might be atopic dermatitis, a skin condition affecting 20% of the population, which can lead to eyebrow loss.
