how to change color of clothing under hair

Hi!

I would like to suggest another way to accomplish what you want. With your layer selected, choose Color Range from the Select menu. with the eyedropper tool, click on the green area and then change the fuzziness slider until you have the majority of the sweater. Then choose the Eyedropper with the plus and click on the shadow areas of the sweater to add them to the selection. When you have everything selected click ok.

With the sweater selected, choose Cmd-J to create a new layer with just the sweater. I used two options to change the color, but you can use any number of ways. I added an Hue/Saturation Adjustment layer and changed the values to a sandy color and also added a Layer style and set the Blending Mode to Color. 

Here are the results

Using Color Range is really a great option when you have large areas of solid color, and take a close look at the clothing under the hair. 

Let us know if you have any questions!

The thing, as I see it, is that both areas may need to be decontaminated – the one that gets colorized and the one that should stay the same. 

And at current I see no good option to avoid manual input to achieve that in many cases. 

I think you should clip the shirt in a Group of its own (within the transparency), decontaminate the edges on both sides and go from there. There are many ways for colorizing, but especially in a high volume case I would prefer a Solic Color Layer set to Blend Mode »Color« and a Curves Layer to edit the luminance. 

The reflections on the chin and trousers you could neutralize or include in the color correction.
