I have the same issue, seems there are three ways to do this in Poser.

First, learn how to use Posers hair room, its a bit like learning to hair style, I think once you have learnt this ist will be the best way, cant comment on how it looks as I havent started on it yet.

Second, use the morph/control handles of conforming hair, I think this would be hard to make look realistic and would indeed be very time consuming, I havent tried this as I just dont have the stomach for it.

Third, I have heard of people trying to clothify some conforming hair (in the same way as you can turn conforming clothing into dynamic clothing). I havent tried this, and my bet is that it will be a chore, but you may get lucky.
