Eyelash extensions are used to enhance the length, curliness, fullness, and thickness of natural eyelashes. The extensions may be made from several materials including mink, synthetic, or horse hair. The main method of applying the extensions on is by using an adhesive glue to individually sticking them to the eyelashes one-by-one. This is to prevent the eyelashes from sticking together. False eyelashes and eyelash extensions are not the same.
