I need URGENT help

[Tzocas]

I have several photos from which I need to remove the background. Some have chroma keys, others have a normal background. The problem is that when I remove the bottom of the hair, for example, some remain green.
How do I remove the green color and get the original color of things?
I have the Adobe Photoshop CC 2019 version
Thank you!!!

To remove green fringing after masking, add a new layer immediately above the masked layer. Alt -click in the layers panel to clip the new layer to the masked layer below. Set the blending mode of this new layer to colour. Now take a soft brush and Alt+Click on the hair to pick up the hair colour. Brush on the new layer around the hair edge to cover the green fringing - this will change the green to the hair colour. The colour will be restricted to the hair edge by the clipping.  Work your way around and Alt-Click as you go to pick up different colours where the hair changes.
