How to change hair color range ?

Hi, i am new to photoshop and need help with something i want to do.
I want to change hair color on a picture (from black to blonde). Those pictures are textures for a game so it is pretty clean and easy to edit usually i guess.
I have another pictures with the blonde hairs tones and colors in it.
So i figured i had to save color range or something on the blonde hair picture to apply it on the black hair picture, right ?
But i wasn't able to find how to do that :(

Thanks in advance for your help all ! ;)

Here's what I would do:
Click select>color range, then click on a spot on the hair so you select the most of it *you could do this manualy, but it probably takes longer*
Click Image>adjustments>replace colors, then you click on the hair again so photoshop knows which colors to replace, then you mess around with hue/saturation/lightness until you come up with a blonde-ish color.

nope, this is bad technique.
