Make your eyes pop or simply eliminate the need for mascara. Eyelash Extensions last between 4-6 weeks, growing and shedding with the natural lash. Thicker, longer, curlier individual lashes are applied one by one to the natural lash using a safe and long lasting glue. While the extensions can last up to 6 weeks, we recommend refills every 3-4 weeks in order to maintain the look. All sets below can be altered to suit your needs.
