There are some people whose eyelashes will keep falling off, even when they wash their face or rub their eyelashes, and their eyelashes may be shorter and unhealthy, and the direction of growth may be unstable. Overall, this indicates that there is a problem with the eyelid, which means that the follicular roots of eyelid lashes may be unstable, malnourished, and stimulated by a variety of inflammatory conditions in the eyelid. Usually in this group of patients who tend to lose their eyelashes, the eyelids tend to be hypertrophic, there may be a variety of secretions, and even scaling, and some of them commonly lose their eyelashes, and if an eyelash is plucked for microscopic examination, a mite infection may be seen. So the most important cause of eyelash loss is definitely inflammation and malnutrition of the ocular surface to varying degrees.
