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.

Ah, thank you I learned something! I thought the map would completely overrule the numeric setting, but if it doesn't it is another way of getting the same result. If I can still modify the specular value on those odd occasions when I need to then I will try that method in future as it is slightly less work. Reducing wasted effort is always a good thing.
