I have a long hair, and had never had any issues with my hearing aids. Unless you mean when you put hearing aids on, you notice a few strings stuck under ear molds, and yank it out? I get that sometimes, but it doesn't bother me. I just push my hair back, so I put it on. I always thought glasses are far worse than hearing aids. *sighs*
I always use hairspray first before putting my hearing aids on. Hairspray is not good for hearing aids.
