This technique developed by beauticians and cosmetologists to improve the beauty of the eyes: to get thicker, longer and more beautiful eyelashes. Originated in Japan at the start of the millennium, it became popular in 2004 and 2005.
Single synthetic fibers made of polyester materials are added to natural eyelashes to get a fuller look. Using surgical grade adhesives, synthetic lashes are applied one to one natural lashes. Only licensed aestheticians may legally apply eyelash extensions in certain states. The procedure takes approximately one hour and a half to two hours for a full set of extensions. They may be worn while sleeping, swimming or showering and may last indefinitely with refills every two to three weeks, depending on the cycle of hair growth. As the hair has its natural cycles, “growth phase”, “declination phase”, and “shedding phase”, the lash falls out naturally in the third phase, the shedding phase, dropping out the extensions with it. And a new growing cycle begins.
During the application, the stylist will isolate a natural lash and attach one lash extension to the isolated hair about 1 mm. from the lash line so the extensions do not touch the skin, irritating the eyelid, or stick to each other.
Artists like Nicole Kidman, Star Jones, Jennifer Lopez, Paris Hilton, Jennifer Love-Hewitt, Lindsay Lohan, Gwen Stefani, Lucy Liu, Naomi Campbell and Liz Hurley are fans of eyelash extensions and the list keeps growing.
Extensions come in different thickness, lengths, colors and curvatures. The choice of the right length, curvature and thickness of extensions must be done by a specialist, according with the client characteristics and lash size. When improperly applied, for example, if extensions are thicker than what they have to be, the hair follicle is stressed and the natural eyelashes are forced to drop out, falling out before their natural cycle. When properly applied, an extension will remain in place until the natural lash on which it rests falls out. Extensions applied one by one look completely natural, unlike the lashes applied as strips or clusters.
Due to the advanced procedures and regulations, they are harmless, lightweight and comfortable.
