Just like natural eyelashes, the extensions fall out. They needed to be filled up about every 2-3 weeks. This is for Russian and Mega Volume sets and must be within 2-3weeks of initial set being applied or a new set will be required. Must have 40% of original lashes remaining.
Infills only applicable to new set's applied at Elinasworkroom. Removal and new set will be needed for lashes applied elsewhere.
A number of things can affect the period of how long the lashes will last, and to make the most of your lashes, avoid any oil based make up products, getting them wet, using mascara or adding any additional adhesives like false eyelashes. The more you care for them, the longer their chance of survival. Your bodies natural make up and lash construct will play a large role - eyelash thickness, volume, and natural oil production levels will be contributing factors.
Should you accidentally get them wet, a gentle blow dry with a cold fan can be used.
