Eyelashes aren’t just a pretty feature on the body; they have a very specific and important function. Eyelashes are designed to prevent objects from getting in the eyes.
The lash line has about 90 to 150 lashes on it, which grow in three-phase growth cycle and eventually fall out.
The anagen phase is also called the growth phase. This is the phase when lashes are actively growing, and it lasts between 30 and 45 days.
The catagen phase is also known as the transition phase. During this phase, the lash stops growing and the hair follicle shrinks. If an eyelash falls out or is plucked out during this phase, it won’t grow back right away because the follicle needs to complete the catagen phase before it can move on to the next one. This phase lasts between two and three weeks.
The telogen phase is also referred to as the resting phase. This phase can last more than 100 days before the eyelash falls out and a new one begins to grow.
