Eyelash Extensions lengthens and thickens your own natural eyelashes. Lash Extensions are single strands of synthetic eyelashes that are curved to replicate a natural eyelash. They are applied to each individual natural eyelash one by one for a natural, beautiful, and luscious look. Eyelash Extensions are perfect for special occasions or for day to day wear. Each lash is individually applied, resulting in a completely natural look and feel. The lash application will last for up to 2-5 weeks, depending on the care and life cycle of your own natural lashes.
