Like hair extensions, eyelash extensions add length to human eyelashes eyelash. Synthetic single fiber polyester thread-like materials are applied to eyelashes to create a fuller, longer look.

 Extensions come in various lengths, colors and thicknesses, and can be worn during sleep, showering and swimming. However, excessive exposure to oil can weaken adhesive bond. 

Eyelash  extensions differ from "fake" or "false" eyelashes in that they are applied one extension to one lash. The procedure to attach the extensions takes an average of half an hour for a full set of extensions of roughly 30-50 lashes per eye.

Eyelash extensions may last from three weeks to three months, depending on the cycle of your hair growth. While the artificial lash is placed directly upon the natural lash, they both will fall off naturally as your lashes cycle out and regrow. Most people choose black lashes, however, brown, red, green and purple are available. Colored lashes are good for accents. Mink lashes are available, and are sustainably harvested from live minks in the United States. The minks are combed out, their hair sanitized and the individual hairs are used.
