Here's why:
* Eyelashes grow from follicles in the skin: Like the hair on your head, eyelashes grow from follicles beneath the skin. Trimming the ends of the lashes doesn't affect the follicle, which is where growth happens.
* The growth cycle: Eyelashes have a natural growth cycle of about 2-3 months. They grow to a certain length, then stop growing, rest, and eventually fall out. Trimming doesn't change this cycle.
* Potential risks: Trimming eyelashes can be risky. You could accidentally cut them too short or poke yourself in the eye.
In summary, trimming eyelashes will only make them shorter, not longer.
