Hi geeks have seen a few threads that discuss this , when we were shown how to do cluster lashes we were told just use the glue that comes with them we did , it lasted about four hours on me . Obviously if I am going to offer cluster lashes I want them to last longer than this I understand why I cannot use semi permanent lash glue but what is then best to use I am sure the lashes we applied were salon sevices ones even the tutor advised they woulld only last the night . Any help would be appreciated ♥
