How long will Eyelash Extensions last?

Your natural eyelashes fall out and replace themselves every 60-90days. With professional application and simple care, your extension will last the life of your natural lash cycle. When your natural lashes fall out in regular intervals, the extension falls off with it. This causes gaps between the extensions. 

To keep your lashes looking full and voluminous, lash refills are recommended every
3-4weeks (to fill in the areas where new lashes are growing in).
Some clients can last up to 5-6 weeks without have a lash refill.
