Question: How would you change her hair to black!? Can someone possibly edit this for me!?

Could someone help me a little!?
My friend wants me to edit her picture of her and her boyfriend!.

and make her hair look black!.
I know how to change it to other colors, but not black!.
And I only have Gimp, not Photoshop!.
Could someone please change her hair to black!?
Is that ever possible!? Haha!. So yeah, I really need the favor!. <33

For what its worth I did this with the 'burn' tool!.
