First thing to try would be: select the hair, then go up to "figure", and select "conform to..."...this will put you in a separate window where you can choose what figure it will conform to, typically figure 1. If that doesn't work, select the hair and hit "object", and hit "change parent". It will give you a list, scroll down until you see figure 1's head, and select that. One or the other should work. I am a bit new to poser also, so if someone out there can add to this, please do. Happy posing.
