Eyebrow loss also known as superciliary madarosis can be quite distressing for women as your eyebrows are a major feature of your face and presentation.
Thinning eyebrows aren’t simply the result of over-plucking. Sometimes, women experience thinning eyebrows as a result of a medical condition or the aging process.
Several conditions can contribute to the appearance of thinning eyebrows:
-
Nutrient deficiency. If you’re deficient in your vitamins and minerals, your whole body will start to show it. Vitamins A, E and D promote hair growth, and vitamin B mitigates bodily stress responses, which can prevent hair loss. A deficiency in any of these vitamins can cause thinning eyebrows.
-
Hypothyroidism. Interestingly, an underactive thyroid can cause women to lose one-third of the hair on their eyebrows.
-
Eczema. Although the flaky, itchy skin condition known as eczema can occur anywhere on your body, patches of eczema underneath your brows can cause hair loss throughout the eyebrow.
-
Alopecia Areata. Alopecia is an autoimmune disease that causes your body to attack your hair follicles, which can include hair on the eyebrow.
-
Medical treatments. Chemotherapy for cancer treatments can cause hair loss, including on the brow line.
-
Aging. Unfortunately, the aging process can cause hair loss or thinning over the entire body, including the eyebrows.
