2 Week Refill – If you first application was done correctly and the client maintained the lashes properly a refill at 2 weeks will be minimal and only 20 – 25 fans per eye will be needed
3 Week Refill – This is the most common and recommended refill time and if the application and client aftercare was followed correctly you would attach anywhere from 25-45 fans per eye.
Any refill past 3 weeks is never recommended. The lashes will get to sparse and look uneven. Your client is your billboard keep your work fresh.
