Eyebrow Loss: Thin, sparse, and easily falling eyebrows often indicate qi and blood deficiency, common in those with weak constitutions and frequent illnesses. Such individuals typically experience cold hands and feet, along with weakened kidney qi. Patients with hypothyroidism or anterior pituitary insufficiency frequently lose eyebrow hair, particularly in the outer third of the brows.In the early stages of leprosy, the skin at the outer edge of the eyebrows thickens, leading to eyebrow loss. Alopecia areata patients may also experience simultaneous eyebrow loss. Cancer, syphilis, and severe anemia can also cause eyebrow loss, and some anticancer or antimetabolite drugs have this side effect.
Eyebrow drooping: Most commonly caused by facial nerve paralysis. Unilateral drooping indicates paralysis on that side, preventing upward elevation of the eyebrow. In some cases, unilateral ptosis (e.g., in myasthenia gravis) may make the eyebrow appear higher on that side.
Dry, brittle eyebrows: Straight, dry ends in women may indicate irregular menstruation, while in men it often suggests neurological disorders. Children or malnourished individuals with yellow, brittle eyebrows may exhibit signs of lung qi deficiency.
Thick eyebrows: Those with dense eyebrows typically possess robust constitutions and abundant energy.However, excessively thick and dark eyebrows in women may indicate hyperfunction of the adrenal cortex. Those with coarse, short eyebrows tend to be impatient and quick-tempered, and should be vigilant against acute illnesses.
Eyebrows Standing Upright: Eyebrows standing upright signal a critical illness; such patients require urgent medical attention.
Slanting Eyebrows: This indicates severe illness, particularly serious disorders of the gallbladder.
Long, Thick Eyebrows: This is often a sign of robust health in the elderly. The eyebrows appear beautiful and long, with some hairs reaching 4–5 cm, and others 2–3 cm.Traditional belief holds that long eyebrows signify longevity, hence they are called "longevity eyebrows." However, clinical observations and family history studies suggest their appearance may not be auspicious. Research indicates longevity eyebrows primarily relate to regulatory imbalances. Their emergence in young and middle-aged adults may represent early external manifestations of latent conditions, including tumors and immune disorders.The earlier longevity eyebrows appear, the earlier regulatory imbalance occurs, accelerating the pace of aging and increasing tumor risk. Thus, their emergence after age 45–50 aligns more with physiological aging patterns, though they should typically appear singly. Individuals with longevity eyebrows in young adulthood—especially those in tufted or clustered patterns—should undergo regular checkups and follow-up monitoring for early detection and treatment.【Friendly Reminder】
The body's defense mechanisms rely on various tissues, and even delicate eyebrows serve a protective function. They prevent dust or sweat from the forehead from entering the eyes, ensuring uninterrupted vision. Some women, seeking perfectly arched brows, often forcefully pluck numerous "unwanted" hairs.Some even remove all eyebrow hair entirely, then painstakingly tattoo new brows—a practice highly detrimental to health. Eyebrows serve a vital purpose: without them, sweat and rainwater can directly enter the eyes, irritating the cornea and conjunctiva. This can lead to keratitis and conjunctivitis, potentially causing corneal ulcers in severe cases.The area around the eyebrows is rich in nerves and blood vessels. Frequent plucking can irritate these structures, disrupting facial muscle coordination and causing symptoms like pain, blurred vision, or double vision. It may also trigger dermatitis or folliculitis.Furthermore, frequent eyebrow plucking can cause eyelid laxity and increased wrinkles, affecting appearance. Therefore, we remind beauty-conscious women: natural beauty is best left untouched—avoid plucking eyebrows lightly.
