A full of set of lashes can look great for a couple of weeks, but naturally lashes will start to shed. Everyone’s eyelashes fall out at different intervals, but on average we lose around 42-70 lashes a fortnight. So, when you start to see gaps in your lashes, as eyelash extensions are bonded to the natural lash, we recommend lash infills are carried out every 2-3 weeks to keep the set of eyelash extensions looking full. By this time, the new lashes which were too short to apply extensions to when you last had your lashes done will now be a healthy lash.
