The eyelash fall season is a natural process that occurs twice a year, in spring and fall, when temperatures begin to change. It's important to be aware of this process, as it's normal to lose up to five natural eyelashes every day. This adds up to 35 eyelashes in a week, which is approximately 20% of the eyelash extensions in a set. The average person loses up to 20% of their natural eyelashes every two weeks and new hair growth is constant.
Eyelash cycles occur every 2-3 months, and the active eyelash growth phase (anagen) lasts up to 30 days and the transition phase (catagen) lasts between 14 and 21 days. This is also known as the transition stage because the eyelash is about to fully grow and enter the last period of its life, the telogen stage. It's important to inform customers about the natural eyelash loss cycle and the seasonal consequences of eyelashes so that their expectations are adjusted well from the start. Regular cleaning is also essential; many people fear that cleaning will cause their eyelashes or extensions to fall out, but gentle, regular cleaning will help maintain their eyelashes and keep them healthy.
It's very common to lose up to seven eyelashes a day, but since they're in a constant renewal cycle, there's nothing to worry about and, in general, you don't even realize it. The catagen phase is the next stop in the vital journey of eyelashes, in which they are approximately halfway through fully growing and have a short break from growing.
