HI Thunderstorm
The best way to remove the adhesive off the end of the hair, would be adhesive remover, such as the Pro Touch adhesive remover.
Pour a small amount of the remover in a container and dip the end of the hair into it, just for a seconds. (10) carefully take a comb and break up the adhesive in the system. After removing the glue wash and condition the system as normal.
Please let us know if you have any other questions!
Have a good day!
