If you connect your transparency map to the specular value input then you can't change specularity on the hair from 1 in the non-transparent areas.

Try it and see! You can keep the Specular_Value of 0.8 that you have, but it will be multiplied by the transmap plugged into that input. When the map is white, you'll get specularity of 0.8 controlled by your specularity map; when it's black specularity is over-ridden to zero. It's functionally equivalent to what you've done by multiplying your specularity and transparency maps in Photoshop.

I didn't even think about the actual transparency settings they are unaltered from the original material on the hair.

That arrangement is common enough, and I wasn't trying to crtiticise it since it will work. Expert opinion (i.e. bagginsbill!) says that Transparency_Edge is best avoided anyway; it's a hold-over from Poser 4 and no longer works properly. You can achieve a better effect with Edge_Blend, but that's straying off topic.
