DO switch out your pillowcase.
As if you needed another reason to love your silk pillowcase. Not only does it prevent wrinkles, but it also prevents damage to your lash extensions! As you toss and turn at night, your face (and lashes) rub against your pillowcase. While cotton causes friction, silk glides smoothly, meaning your lashes will last even longer.
DON'T be rough!
You will definitely be tempted to fuss with your lashes once you get your extensions, but do not pick or pull at them. Just like the hair on your head, your natural eyelashes go through a shedding cycle. Tugging on your extensions can cause your real lashes to shed prematurely. Unfortunately, just like your hair, lashes are not infinite. You can only pull a lash out so many times until it never comes back, so be careful!
DO maintain your lashes.
Just like you keep to a strict schedule for your waxing or hair color appointments, you need to go in for your regular eyelash tune-up. Get fills no later than every three weeks to keep them looking fresh, full, and even.
