I maaay be bias as I’m a lash technician but I absolutely adore them.
On an average, a new set should last you 5-6 weeks. However it’ll thin out as you’re not upkeeping them. If you choose to upkeep them, you’ll have to go in every 2-4 weeks depending on your lash cycle.
A lot of my clients get them refilled every 3-4 weeks. And then I have some one-off clients that only come once or twice a year just to get them on for vacations or special occasions.
If you’re having retention issues, voice your concerns to your lash tech and he/she will go over aftercare with you or adjust the amount of glue needed to adhere the extensions.
It’s pricey but sooo worth it, waking up and going to sleep extra cute is always a plus.
