I use antje brushes, well 1 brush to be precise, photoshop i think it the best to do hair in, I can't seem to get the pressure thing right in Paint shop pro and I haven't tried any other programme.

If you are looking for an easy tut, try mine, it's not totally realistic but my freebies down down well.

My rule basically is, 1 brush, 2 colours, 2 layers, burn and dodge, there is variations to that rule but that's mainly it. Also you don't need to go down the road of having every strand showing, look at someones hair, you can't see every single hair, just an impression of the texture so why paint it.

If you try, let me know how you get on :o)
