If the back part of the eyebrows is unusually thinning, it may be hypothyroidism.
If one-third of the back part of the eyebrows has fallen out, it could be due to hypothyroidism. Hair loss at the back of the eyebrows is a symptom that often appears in patients with hypothyroidism, also known as Hertoghe's sign. Thyroid hormones are involved in regulating the growth, differentiation, and metabolism of somatic cells, as well as body heat. When this function does not work properly, hair grows slowly, becomes brittle, and hair loss occurs. This effect also impacts the eyebrows. If you feel like the outer part of your eyebrows is continuously falling out, it is advisable to undergo a thyroid function test.
If the area around the eyebrows is itchy, red, and has thinning hair, it may be 'psoriasis'.
Dandruff around the eyebrows, itching, redness, and sometimes hair loss of the eyebrows occur. In such cases, psoriasis is suspected. Psoriasis is a chronic inflammatory skin disease that appears at the skin boundary. According to the Korean Psoriasis Society, psoriasis usually appears on the scalp, elbows, and knees, but it can also appear on the face. Facial psoriasis mainly occurs around the eyebrows, the philtrum, the upper part of the forehead, and the hairline. The face is a particularly sensitive area of the body, so delicate treatment is necessary.
If there are round bald spots on various parts of the eyebrows, it is 'Alopecia Areata'.
If your eyebrows are falling out and there are several round bald spots, it could be alopecia areata. Alopecia areata refers to round or oval patches of hair loss (areas where hair has fallen out and appear as small spots). It mainly occurs on the scalp but can rarely appear on the eyebrows as well. It can also sometimes appear on eyelashes, beards, or pubic hair. To prevent alopecia areata, you should avoid severe mental and physical stress in daily life. It is best to refrain from activities that can strain the body, such as severe dieting, smoking, and drinking alcohol.
