Whats the best way to remove these foils, having a dispute with my mates at salon can you give me your methods of best removal.

I've always used foils however some of the girls in my old salon used easi meche and always removed at basin with abit of water to losen them x

If they are used correctly, with the tint covering the sticky strip, they should just slide off. You can also put water on them to remove them.
