Besides drop-dead gorgeous and the ultimate time-savers, what are eyelash extensions anyway?

Put simply, lash extensions are small, synthetic fibers that are carefully attached to the base of each natural eyelash. When applied properly, these little lashes make a big difference, so that short and sparse eyelashes become full, long and luscious.

Eyelash extensions come in a variety of different lengths, diameters, and styles. They attach to each eyelash with lash adhesive (aka glue) designed specifically for the eyelash area. If you have sensitive skin, there are also adhesives and under eye gel pads made specifically for you!

There are three main types of lash extensions—mink, synthetic and silk. You can read about the differences between mink vs. synthetic vs. silk lashes here. Regardless of your choice, your lash technician will help create the best lash curl and length for your eye shape, natural lash size and makeup preference.

How Long Do Eyelash Extensions Last?

Now onto the main question: how long do lash extensions last?

Generally, most salon-applied eyelash extensions stay for anywhere from two to four weeks. This takes into account that some lashes will fall out prematurely, especially within the first couple of days.

However, the answer varies greatly because it depends on how experienced your eyelash technician is, what adhesive is used, the life cycle of your natural lashes, and, most importantly, how you care for them.
