Eyelashes
Eyelashes are hair-like structures that grow on the eyelid and serve to protect the eye from dust, debris, and other foreign objects. They are made of a protein called keratin and are attached to small muscles that allow them to move and respond to touch. The growth cycle of eyelashes is about 60-100 days, and the length of the eyelashes can vary from person to person.
Eyelashes also have a cosmetic function, many people use mascara or false eyelashes to enhance the look of their lashes and make them appear fuller and longer.
Eyelash extensions are another way to enhance the look of lashes, in which individual synthetic or natural hair fibers are glued to the natural eyelashes. This can create a fuller, longer, and more dramatic look, but require maintenance and touch-ups every 2-4 weeks.
Eyelashes can also be affected by certain medical conditions, such as alopecia, and eyelash growth can be improved with the use of certain topical medications or serum.
