Why do eyebrows not grow longer like the hair on your head?
Eyebrows are important for framing the face and protecting the eyes from sweat and debris. Unlike the hair on your head, eyebrows have a much shorter growth cycle. The average eyebrow hair grows about 0.15 mm per day, or about 5 mm per month. This is much slower than the hair on your head, which grows about 1.25 cm per month.
There are a few reasons why eyebrows don't grow longer. First, the hair follicles in the eyebrows are not as deep as the hair follicles in the scalp. This means that the hair shafts are thinner and weaker. Second, the eyebrows are exposed to more friction than the hair on your head. This can damage the hair follicles and prevent them from growing longer.
Finally, the eyebrows are controlled by different hormones than the hair on your head. The hair on your head is controlled by testosterone, while the eyebrows are controlled by estrogen. Estrogen promotes shorter, finer hair growth.
While you can't make your eyebrows grow longer, you can take steps to keep them healthy and looking their best. Avoid over-plucking or waxing your eyebrows, and use a gentle cleanser to wash them. You can also apply a moisturizer to keep them hydrated.
