What are eyelash extensions?
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. Strip lashes can be applied by anyone. Professionals typically apply individual lashes. Our guide focuses on the latter because they're more complicated, not to mention expensive.
Eyelash extensions are a cosmetic application used to enhance the length, curl, fullness, and thickness of natural eyelashes. The extensions may be made from several materials including mink, silk, synthetic, human or horsehair. 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.
