When eyelashes are removed, in most cases they will grow back. If a little bit of the eyelash is removed, some of the hair and follicle areas in the dermis will grow back, such as the hair follicles from the original hair matrix cells, which will eventually produce hair, so the eyelashes will gradually grow back. However, in some people, due to individual differences, the eyelashes may not grow back. If this happens, there is usually treatment available, which can be a localized hair transplant treatment, which can improve the appearance of the area.
