Eyelash extensions are a cosmetic application used to enhance the length, curl, fullness, and thickness of natural eyelashes to your natural eyelashes in order to make your lash fringe look longer, fuller, and darker. The extensions may be made from several materials including mink, silk, synthetic, human, or horsehair. Mink extensions tend to be the lightest and softest, which is why some people believe they're the best fake eyelashes. It's also why they're the most expensive. Synthetic lashes are typically the thickest and heaviest of the bunch, resulting in a highly dramatic look. Synthetic silk extensions are the most common type of extensions used nowadays because they tend to be fairly light, very dark, and able to hold a curl. Lash extensions are tiny black fibers that resemble eyelashes and that are attached to natural eyelashes using glue. The fibers either come as individual pieces or attached to a strip. 

Unlike temporary false lashes, eyelash extensions are neither a D.I.Y. affair nor a fleeting commitment. The main method of applying the extensions is by using a cyanoacrylate adhesive to apply the extension(s) to the natural lash 1-2 mm from the base of the natural eyelash, never making contact with the eyelid. They are professionally applied, one on each natural lash, with a semi-permanent glue, meant to hold them in place for several weeks. Extensions bewitch your lashes with the length and volume that nature didn’t see fit to give you (and beyond what multiple coats of mascara and a lash curler could), but at a length your face deserves.
