Around 2 to 3 weeks after your initial lash appointment, some of your natural lashes will have reached the end of their life cycles and shed. You will start seeing little gaps where the old ones have fallen, with new baby lashes coming through – at this point it’s a good time to get infills, so your lashes always look nice and full. Once a baby lash is mature and strong enough to hold an extension, we can apply a lash there. Any lashes that have grown out more than about 3mm, we remove gently by peeling the extension off (this is needed as otherwise they will start to twist/droop). Your lashes are not cut during the process. Some people can go 4 weeks between infills, but this is unusual unless your lashes grow very slowly. We will infill as long as around 40% of the lashes are left. If you’re unsure if it’s an infill or a new set, feel free to get in touch and we can assist!
