Most of us lose 20-30% of our natural lashes in 2 weeks, which is why it is recommended you get a fill every 2-3 weeks to ensure your lash line stays nice and full. My fill policy is that you are required to have at least 50% of your lashes in order for it to be considered a "fill". If you book a fill and show up with less than that, you will be charged for a full set. If it looks like you need a fill then you have waited too long. Lashes should look good all the time!
A lash fill involves applying eyelash extensions on new hair growth (new lashes) to give your lash line a full, gorgeous, refreshed look. both services begin by cleansing and then removing and long or overgrown eyelash extensions followed by replacing and applying new extensions. a full refill includes 25-45 new extensions applied per eye to really perfect that full look. if more always equals better for you, you can always vamp it up with, 10, 20, 0r 30 extra lashes. :)
