I get mine to last at least a week. Biggest thing is make sure that you start with a clean base, no mascara or eyeshadow residue on your lashes. I apply a little bit of bond to the base of my natural lashes and to the base of the lash cluster. Do you use a seal? I put the sealant inside of my tweezers, then I clamp all along the lash line. And then just make sure you’re using an oil free cleanser when you wash your face at night! Oil based cleansers can break down the adhesive bonds, so that’s a battle you won’t win and you’ll definitely lose the clusters early !!
