Thanks for the reply, Ockham.

This is a hair figure I'm dealing with specifically, not a prop. Yes I made sure the zone was where I needed it to be. I use magnets all the time for clothing and adjusting body parts.

The hair figure is the FK Twins pigtails from 3DCommune. I've tried sizing it with the various scale dials, but it doesn't react well since it's conformed. I have used magnets on other hair figures without a problem, but this one and some props just seem to ignore the deformers.
