We all lose lashes everyday. But we don't notice it until we get lash extensions. It's totally normal. That being said, we need to be more aware of the lash shedding season. Twice a year, we will all experience lash shedding more than usual. And those seasons are in spring and fall. This tends to happen more in those seasons due to the fact that the temperature changes. In the fall, the weather is colder, it makes our natural lashes more brittle and fall out easier. And in spring, it gets warmer, we sweat and produce more oils which affects retention. Also, think of it as "spring cleaning", old natural lashes fall out in order to make room for new healthier lashes. Lash shedding season is temporary! Unfortunately, there isn't anything we can do to prevent that. What we can do is educate ourselves and be aware when booking refills. Please don't worry too much. All lash artists are going thru the same thing.
