Extreme lashes are like hair extensions, but on your eyelashes. Each eyelash is glued on individually to your own natural eyelash. They last until your eyelashes fall out naturally. Eyelash fills are done every 3-4 weeks. I had this done about a month ago and I find that my extreme lashes are falling out even without my natural eyelash falling out. Does anyone here who have this have this problem too? Also some of my extreme lashes are starting to go sideways. Should I quit these extreme lashes or give it some more time?
