What Causes Eyebrow Hair Loss > 자유게시판

Eyebrow hair loss can occur due to various triggers, some of which are transient, while others require professional intervention. One of the most common culprits is excessive tweezing. Consistent trauma to the hair follicles from harsh beauty routines can permanently weaken the follicles, resulting in thinning brows in severe instances. Skin conditions such as atopic dermatitis can irritate the eyebrow region, disrupting the natural hair growth cycle.

Another prevalent cause is alopecia areata, a condition where the body’s antibody response destroys hair follicles, leading to circular bald spots, often extending to the eyebrows. Thyroid imbalances—both hypothyroidism and hyperthyroidism—are strongly associated with eyebrow thinning, particularly the lateral portion of the brow, a well-documented symptom of an underactive gland.

Micronutrient shortfalls can also contribute significantly. Deficiencies in key nutrients like protein can weaken hair follicle integrity, triggering increased shedding. This pattern is frequently observed in individuals with restrictive diets.

Hormonal shifts—such as those occurring during starting or discontinuing birth control pills—can temporarily disrupt eyebrow hair loss as the body adjusts to changing estrogen and progesterone levels.

Therapeutic agents—including retinoids—may list hair loss as a potential complication. Microbial invasions, especially fungal infections, can invade the skin around the eyebrows, killing follicles and preventing regrowth.

Scarring events such as accidental damage can permanently obliterate hair follicles in the affected zones, making regrowth unlikely.

Physical stressors—including overexertion—can induce stress-induced shedding, a condition where a large number of follicles enter early a resting phase, leading to excessive loss in facial and کاشت ابرو در کرج head hair.

Finally, biological aging gradually reduces hair growth rate and thins eyebrow density over time, resulting in more sparse brows as we grow older.

If you experience rapid thinning, it’s advisable to see a healthcare professional to identify the root cause and explore therapeutic options.
