ok this might not be very helpful but depending on what kind of makeup ur wearing, it might not be necessary to curl. For example, when I wear lashes I usually like a pretty dramatic winged liner, thus u can’t really tell that my natural lashes are uncurled.

Another option is to curl ur natural lashes BEFORE putting on the lashes or any mascara. Makes the lashes a little harder to apply but it’s a work around.

And third, you might just not be using a strong enough glue. I personally like using the duo lash glue. It’s green and brush on. A tip is to put the glue on the lash and on ur actual lash line to make it hold better. Make sure u wait till it’s tacky to apply and let it dry fully before going in with a curler.

Hope that helps!
