After I get my lashes done here I don't see a single lash fall out until at least 10-12 days after I've gotten a fill which is AMAZING! Whenever I've gone to other places it seems I look at myself in the mirror, blink once, & 2 fall out without one of my natural lashes attached so I know it wasn't a natural eyelash shedding, just poor adhesive and technique. SO happy I found Linette!
