The function of the eyelashes:
Eyelashes aren't just a pretty feature of the body; they have a very specific and important function. Eyelashes are designed to prevent objects from getting in the eyes. Each eyelash is actually a sensory hair that reflexively shuts the eyelid whenever it is touched by dirt,dust or anything else that could possibly get in the eye. The upper lid typically has about 100 to 150 lashes on it , while the bottom has between 70 and 80 lashes. Most eyelashes grow about 10 mm long.
Eyelash and hair growth:
Although it may not seem like it, hair growth is a preset function of the body. Every hair on your body follows a specific growth cycle and will grow a specific length. Hair follows a three-phase growth cycle and eventually falls out, which is typically nothing to worry about . In fact body hair, including eyelashes, completely replaces itself for example:
•Anagen ( growth) Phase
•Telogen (resting) Phase
The anagen phase is also called the growth phase . This is the phase when lashes grow and it lasts from 30 to 45 days. Only about 40 percent of the lower lashes is in the anagen phase at any one time. Each lash will grow to a specific length and then it stops.
The catagen is also known as the transition phase. During this phase the lash stops growing and the follicle shrinks. If an eyelash falls out or is plucked out during this phase, it will grow back right away because the follicle needs to complete the catagen phase before it moves to the next one. This phase lasts from two to three weeks.
The telogen phase is also referred to as the resting phase. This phase lasts for 100 days before the eyelash falls out and a new one begins to grow. Since each individual lash is in its own phase of the growing cycle, it's normal for a new lash to fall out most of the days. It typically needs from four to eight weeks in order for an eyelash to be fully replaced.
