I've been trying to select some fine hairs with the Refine Edge tool, but it always ends up looking terrible. This image is my from my most recent struggle. I shot on a gray muslin backdrop and either a ton of gray bleeds through or almost no hair is selected. I've tried viewing tutorials online, used the exact same settings shown in those tutorials, and my images still look messed up. It doesn't matter what settings I use either, nothing looks natural. I seem to have the biggest problem with lighter hair, but darker colors don't look great either.
Does anyone have any idea why this is happening or how to fix it? I can't give an image to a client looking like this, but I can't really reshoot it either if the results are just going to be the same.

Did the images used in those tutorials feature backgrounds that were similarly structured and bright (in relation to the foreground) as yours?
