Hi I'm a fairly new lash tech, and I have some retention issues on certain clients. I've got one regular who never seems to have a problem, but I've had a couple of new clients who have lost loads in the first few days even when following after care instructions. I'm cleansing the lash, and I've used new glue so I know my adhesive hasn't gone off, but I'm really struggling to resolve the problem and am frustrated that new clients are having a rubbish experience! So it's the extension popping off the natural lash not the extension pulling the lash off. I use a lash primer as instructed by the brand I trained with and cleanse the eye with oil free remover before. What could be going wrong?! Any help appreciated!
