Learn how to change hair color from certified trainer Scott Strong of The Training Farm in NYC in this Howcast Photoshop tutorial, part two of two.


Next, I'm going to hit option on my keyboard, and I'm going to have a look at the layer mask itself. I right click the icon for the layer mask. You can see it comes up. I just want to refine this a little bit, so I'm going to hit "O" on my keyboard, and then "shift-O", "shift-O", under I get to the dodge tool. The dodge tool is going to take all the pixels that are gray, and it's going to make them brighter. I'm just going to brush over that a bit. I want to change my exposure up so I get more pixels at once.

When I"m done, I'll hit "option" on my keyboard and select the layer mask again. Notice that there's a bracket around the layer mask. That means that anything I'm doing is occurring on the layer mask itself. What I want is to select the image itself. What we're going to do is add a color to her hair. I'm going to create a new layer, and I have a brown color hair for her hair. I'm going to select all, and I'm going to fill the entire layer with that color. The foreground color.

The next thing I want to do is gang this layer, the hair color layer, up with her hair. I'm going to hover my mouse over the boarder between the layer and the hair layer, and I'll hold down "option" on my keyboard, and you can see that the icon changes, and I'm going to click right there. Now her hair and the color are ganged together.

The next thing I want to do is change the blending mode of the color so it blends with the texture of the hair underneath it. I'll change it from normal to multiply, and let's try overlay. That has a more natural look to it. It's a little lighter in color, so I'm going to darken it up a little bit. I'm going to do that with an adjustment layer. An adjustment layer will change the pixels of all the layers underneath it. I want to gang that up with the hair layer as well so I'm not changing the pixels in her face.

I'll start by creating an adjustment layer. I'll go to curves, and again, I'm going to hold down "option" on my keyboard. Once the icon changed, I'm going to click. Now anything I do on the curves layer is going to effect only the hair layer. I'll take the midtones and make them a little bit darker.

This is a little bit too bright in color so what I'll do next is add another adjustment layer. Hue and saturation. I want to drop the saturation of the colors in her hair. I'll hover my mouse over the boarder again, hold down option, and now anything I do on the hue and saturation layer is only going to effect the hair. Next, I'll take the slider for saturation and just drop it down. That gives us a much more natural look.

If you want to see the effect that you've done so far, all you have to do is turn the visibility for the hair layer on and off, and you can see that we've changed her hair color using Photoshop.
