What Causes Eyebrow Hair Loss > 자유게시판

Eyebrow hair loss can occur due to a range of factors, 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 overzealous shaping can compromise the follicles, resulting in thinning brows in severe instances. Inflammatory skin issues such as atopic dermatitis can irritate the eyebrow region, disrupting the natural hair growth cycle.

Another prevalent cause is immune system attack on follicles, a condition where the body’s immune system mistakenly targets hair follicles, leading to focal thinning, often including the eyebrows. Hormonal thyroid disorders—both underactive thyroid and overactive thyroid—are strongly associated with eyebrow thinning, particularly the outer third of the brow, کاشت ابرو در کرج a hallmark sign of an underactive gland.

Micronutrient shortfalls can also contribute significantly. Insufficient levels key nutrients like omega-3 fatty acids can degrade hair follicle integrity, triggering excessive hair loss. This pattern is frequently observed in individuals with restrictive diets.

Hormonal shifts—such as those occurring during pregnancy—can trigger eyebrow hair loss as the body adjusts to changing estrogen and progesterone levels.

Therapeutic agents—including retinoids—may list follicular shedding as a common adverse reaction. Microbial invasions, especially fungal infections, can infect the skin around the eyebrows, killing follicles and preventing regrowth.

Physical trauma such as surgical scars can disable hair follicles in the affected zones, making regrowth impossible.

Chronic stress—including illness—can induce stress-induced shedding, a condition where hair growth cycles are forced into a resting phase, leading to widespread shedding in facial and head hair.

Finally, the natural aging process diminishes hair growth rate and weakens eyebrow density over time, resulting in softer brows as we grow older.

If you experience sudden eyebrow loss, it’s advisable to see a healthcare professional to determine the triggering factor and explore therapeutic options.
