Texmod hair glitch, help?

Whenever I texmod armour files, the hair on my character messes up, even when I don't even touch it. It bleeds through all the invisible part to create a solid tone bleed over parts of the mesh you usually can't see. How can I fix this? I'm using paintshop pro, I keep the file in the exact same size and position, and the armour turns out looking fine, but the hair always messes up.

thanks
