hair color question

I'm wanting to make an icon out of the wallpaper here: http://img28.photobucket.com/albums/v83/scifispice80/nikkiscan.jpg

The thing is, I want to make her hair pink instead of red and am having trouble figuring out how to do that. I've already tried filtering a neon glow, and it just gives me this flattish purple-gray color. Even if I desaturate the image first and then apply a neon glow, I still get the same purple-gray. I know I can always use airbrush or something, but then the texture and detail of the hair gets covered up. Does anyone know how I can mess with the hair color without losing the detail and stuff?

I have psp7, adobe photoshop 5 and adobe image ready 3, i think it is.
