What is eyelash extensions 

“Lash extensions are semi-permanent synthetic, faux mink or silk fibers which are applied strand by strand to your natural lashes,” explains Richardson. As you might expect, the application is fairly tedious. “The extensions are carefully applied one at a time using a specially-formulated, semi-permanent glue that will not irritate or damage the natural lash,” she adds.

Unlike false eyelashes, where the strip or individual lashes are applied to the skin, lash extensions are attached directly to the lash itself. The results are more lush, dense lashes that may even let you skip mascara (gasp).

How Long Does the Process Take?

The bad news? Expect the treatment to take one to two hours, depending on your desired look. The good news? You can use it as an excuse to lie down, relax, and take a forced break from your phone.

A good lash technician will take their time, reminds Richardson. “Safety should be your number-one concern. Finding someone who is certified to apply the lashes is a must. Depending on the state, the stylist also needs to be licensed,” she advises.

How Long Do Eyelash Extensions Last?

Because extensions are attached to the lash itself, they last as long as the natural growth cycle, or about six weeks. To extend the life of the extensions, Richardson recommends using a lash conditioner (yes, it exists!) and to gently comb through your lashes with a dry spoolie brush. Its also recommends getting “refills” every two to three weeks to fill in any sparse areas.
