I am planning say in a hotel with a spa and pool soon,and intend to swim in the pool, in my wig, and sue the hot tub. I just put the wig over my fairly short hair - no stocking cap or anything. I always try to keep my head out of the water as I am not a strong swimmer, but realise that this is not always possible. Is my wig likely to float off, and if so, how can this be avoided?
