Anagen - is an active, growth phase which lasts 30 to 45 days for eyelashes. When eyelashes are in this phase, the eyelash keeps growing and they do not fall out unless pulled, plucked or otherwise forced out.
Catagen - a transitional phase where the growing is no longer happening. The follicle at this time is not making hair, therefore if the eyelash falls out during this 2 to 3 weeks, it will not grow back until the follicle's catagen phase is over.This time will be opened for Eyelash nutrition, so that it begins the next stage of the cycle, Li Lash Eyelash Growth Serum is your good choice!
Telogen - is a phase where hair and eyelashes fall out (a phase we do not like but must put up with). This phase is the hair's resting period that lasts for about 100 days before it will fall out on its own. Losing eyelashes in this phase means that a new eyelashes will grow in faster because the natural hair growth cycle was not interrupted.
