Revealing part of an underneath layer

[IamSam]

I think the that area on the mask is faded. Probably caused when you were painting black to hide the hair and the brush was slightly intruding into the white. Touch it up with a slightly soft edge brush using white.

Yep, that's what I said.........

If anything, all you need to do is to make corrections to the layer mask to solve your problem.

Use the Brush Tool..........the first one on the nested drop down list.



Choose a soft brush and and rework that area of the layer mask. Click on the layer mask to make it active. Hit the D key to return your foreground and background colors to their default setting of black and white. Switch back and forth from white and black to alter the mask.
