Quote - You don't need to conform comforming hair just for the sake of conformity. Yes, it was a lousy sentence.  Deliberately so.  :)

Load, position, parent.  That's all yer need, apart from maybe scaling.

Simples.

No, I haven't been drinking or taking funny chemicals.  

Yep there is usually one in every post. That was the reason I stated not to bother telling me to do that.
Try it some time. Parent a conforming long hair .Cr2 to a head not made to have the hair conformed to. Then once parented to the figure's head select the tips of the hair or try to use the dials to make the hair strands....say, fly away and tell me what happens. From my experience the crown of the hair magically blows off the head or lifts off needing repositioning. Not a good thing to have happen because after all the time needed to try and "fit" the conforming hair to a head it wasn't made for you gotta go back and rotate and spin and try to refit it to the head again. But to make it worse you can't really guage how much "fly Away" dialing you have to do if you have to go back and reposition it on the head trying to get it just right.

BTW the reason I parent the hair to the head first is for cutting the additional effort of trying to position and scale it to a head already in a specific pose. Much easier to do so when the figure is in the default pose.
