Hey girl.
I don't know whether you mean the lashes get stuck to the pad or the lashes under?
I had the problem. What you need to do is go through double protection. After applying the pad, apply tape. Even though you think you have applied the pad correctly, there still might be little bottom lashes sticking out. I take 2 little bits of tape, one going from each corner for each eye.
The case of the client having different eyes and lashes actually sticking to the pad, I apply little bit of tape to lift their eyelids. I take maybe a 5cm long tape, put one edge near their lash line, lift the skin of the eyelid and then stick the other half on their forehead/just past eyebrows (make sure the eye is not open when that is done as that will frustrate the customer's eyes)
I've attached pictures, maybe that will make more sense. I know it looks a bit weird but works like magic. Sometimes I have decided to go ahead without the extra tape on top of the pad, as soon as I do that, some lashes have came out and the eyes got stuck.
Hope this helps!
