Once you have the hair fitting the way you want it, with the hair being the active item,   go to "Object" in the tool bar at the top of the screen and "Change Parent" and reparent the hair to the figure's head. The figure in this case would be "V4".

So far as the hair remaining white, it could be that the hair doesn't preview properly in the scene, but will render properly.

Also, what do you have your style settings at?  The style settings is that row of 12 dots. If you click on the down arrow above (or beside, depending on how you have Poser set up), you can change the style.  Pick "DocStyle".  And pick the dot all the way at the end..."Textured"  See if that works. 

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
