The reason for this is too low humidity. You can increase the humidity in the room by using a humidifier. You can also speed up the drying of the glue with ours Glue accelerators. In any case, we recommend that you have different adhesives in stock for different situations – different humidity and temperature. Also, the problem of drying can be caused by the client’s natural lashes if: the natural lashes are too dry, due to hormone treatment, or if you have not cleaned the natural lashes well enough with foam. Consult your client first.
