Xtreme Lashes takes false eyelashes to a whole new level. These synthetic lashes are applied in single strands instead of one full set. The process can take anywhere from an hour to two hours. A stylist will apply the single strands to the base of your eyelid and curl it. The lashes are applied with a special adhesive, so they won’t come off. Xtreme Lashes can last indefinitely. You can reapply individual lashes, as they come off.
