Why do our eyelashes and eyebrows does not grow continuously?

A roughly 90% of your hair follicles are normally in the development stage at any specified point. The hair in your eyebrows just goes through a short-term length, approximately 4 months. The length of your hair is normally perfect before expected time which it has to grow.

Hair follicles have staged growth cycles: one stage for growth, one stage for the lapse and one stage for rest. A roughly 90% of your hair follicles are generally in the development stage at any specified point. The hair in your eyebrows just goes through a short-term cycle length, approximately 4 months in contrast to 3 years for the hair on your head. The length of your hair is generally outdone by the time which it has to develop.

As they are prolonged, these cells die and become the hair we notice. The cells that form the hair on our eyebrows and eyelashes are basically planned to prevent developing for every couple of months, so the hair remains for short-term. Those in our scalp are planned to develop for years at the same time, so the hair grows long.

In fact, all hair prevents growing after a certain length! Leg hair, arm hair, eyelashes, eyebrows, head hair, and even the hair on your butt will stop growing after a specific period of time. Precisely how long your hair can grow relies most importantly on your genes, age, hormones, and common health.
