Lash extensions last approximately six to eight weeks. But since each individual extension is attached to a natural lash, the life you get out of your extensions is mostly dependent on your own natural lash cycle.

When in doubt, a 15-20% tip is a good starting point, but don't hesitate to tip more if you received exceptional service and can afford to do so. Remember, a generous tip can make a lash technician's day and keep the beauty industry thriving.

On average, eyelash extensions usually take 1.5-2 hours to apply - though this estimate may differ depending on the abovementioned factors. Refill appointments, typically required every 2-4 weeks to maintain them, can take 45 minutes up to an hour.
