The duration that implanted eyelashes can last varies and is typically affected by factors like the implantation method, the quality of materials used, and individual maintenance. Here are the details:

- Surgical Eyelash Transplant: This is a more permanent method where hair follicles are transplanted from the scalp or other parts of the body to the eyelid area. The transplanted follicles usually take root and start to grow new eyelashes within a few weeks. After the initial growth period, the newly grown eyelashes can last a long time, generally several years or even a lifetime, as long as the transplanted follicles remain healthy. However, like natural eyelashes, they will still go through a normal growth cycle and may shed occasionally, but new lashes will grow in their place.
- Eyelash Extension Gluing: This is a more common and less invasive method. Eyelash extensions are attached to the natural eyelashes using special glue. Usually, if the operation is done properly and the quality of the glue and extensions is good, they can last about 1 to 3 months. But as the natural eyelashes go through their normal growth cycle and shed, the attached extensions will fall off with them.
- Eyelash Quality: High-quality artificial eyelashes used for extensions are more durable and have a more natural look and feel. They are less likely to break or fall off easily compared to lower-quality ones. For example, mink hair or high-quality synthetic fibers can last longer and maintain their shape better.
- Glue Quality: The quality of the glue used to attach the eyelashes is also crucial. Good-quality glue has strong adhesion and is more resistant to water, oil, and daily wear and tear, which can help the eyelashes stay in place for a longer period. Inferior glue may cause the eyelashes to fall off quickly due to poor adhesion or may even cause eye irritation.
- Daily Care: How you take care of your implanted eyelashes in daily life has a significant impact on their lifespan. Avoid rubbing your eyes vigorously, as this can easily cause the eyelashes to fall off. When washing your face, be gentle around the eye area and use products that are gentle and non-irritating to avoid weakening the glue or damaging the eyelashes.
- Professional Maintenance: Regularly going to a professional beauty salon for eyelash maintenance can also prolong their lifespan. Professionals can check the condition of the eyelashes, re-glue any loose ones, and trim or replace damaged eyelashes in a timely manner.
