Ah, this is the conforming issue I think.

Conforming clothes must be conformed to the figure, then they will follow the figure when you pose it, and scale with it when you scale it. The same applies to conforming hair (hair that loads as a figure). Some hair loads as a prop, and that needs to be parented to the head of the figure, then it will also stay "stuck" to the head.

How I remember my early efforts where the lady would be all dressed and coiffed, and then I make her walk across the screen and the hair and clothes remain behind in mid-air while she walks away naked and bald....
