First of all, set preview of hair to texture shaded. I'm assuming that hair are a unique piece, such as a hair prop or the only visible part of the hair figure. Select them, and go to "object/create magnet", you'll see the three part composing the magnet element. The horseshoe part is the magnet itself, whose relative movement against the base (second part of the magnet, the straight bar) is what creates the modification on the figure. Third part is the zone, represented by a sphere, which is the influence zone of the magnet. Now, shape and move the zone using scale and translate dials until it is approximately around the problematic area, and move/rotate the base such as the magnet curve is in the direction you want tu push/pull the hair. Finally, simply increase the YTrans on the magnet, and you'll see the hair begin to raise from the poke-through. To refine you can play with the zone, increasing its size o rotating it to better fit the poke-through area; you can rotate the base to a better angle to adjust the effect of the magnet, and so on. Notice that the zone influence is bigger toward the centre of the sphere representing it, so don't be afraid to increase its size to encompass even more than the poke through area, just don't overdo it. And if you have Poser7 and don't want to use magnets, the Morph Tool is your friend... :) Problem is...I never used it until now, so I can't help there.
