Starting with the Right Image: Ideal Conditions for Hair Color Changes
The quality of the original image significantly impacts the outcome of a hair color change. Images with good lighting, clear definition, and minimal distractions make the process smoother and the results more realistic. It's advisable to use images with Studio background to ensure cleaner edits.
Images shot against simple backgrounds, or those taken in a studio setting are ideal.
Ideal images should have:
- Consistent and even lighting.
- Sharp focus on the hair.
- Minimal distractions in the background.
- High resolution for detailed editing.
The Cornerstone: Creating a Precise Hair Mask
A precise hair mask is the most critical step in changing hair color in Photoshop. It isolates the hair from the rest of the image, allowing you to apply color adjustments without affecting the surrounding areas. Several selection methods can be used to create a hair mask, each with its advantages and disadvantages.
The main goal is to select the hair as cleanly and accurately as possible. Fortunately, Photoshop offers a dedicated tool and workspace called 'Select and Mask' that greatly simplifies this process.
Popular Selection Tools and Methods:
- Quick Selection Tool: Good for quick, initial selections, especially against clean backgrounds.
- Select and Mask Workspace: Refine edges, create feathered selections, and remove color fringing.
- Channels: For detailed selections of hair strands.
Step-by-Step: Using the Quick Selection Tool and Select and Mask
The combination of these tools offers a highly effective approach for hair masking.
The Quick Selection Tool allows you to rapidly make an initial selection of the hair, while Select and Mask enables precise refinement of the edges.
Here's a step-by-step guide to this technique:
- Select the Quick Selection Tool: In the toolbar, choose the Quick Selection Tool.
- Adjust Brush Settings: Adjust the size and hardness of the brush. A hardness of 100% is used in the example.
- Paint over the Hair: Begin painting over the hair of your subject. The tool automatically detects edges and expands the selection.
- Remove Unwanted Areas: If the selection includes areas you don't want (like skin), hold down the Alt/Option key and paint to remove those areas from the selection.
- Enter Select and Mask: Click the 'Select and Mask' button in the Quick Selection Tool's toolbar to refine the edges.
This is where the magic happens, giving much more precise controls.
-
Adjust Edge Detection: In the Select and Mask workspace, experiment with the radius slider to define the edge of your selection. The tutor uses 4.4 px for their size image.
-
The Refine Edge Brush: Use to paint over the hair which should be included in the selection but is not.
-
Output Settings: Output to New Layer with Layer Mask to keep edits flexible

Clean up hair that has color bleeding over from the background
Transforming Colors: Adjustment Layers for Hair Color
Once you have your precise mask, the next step is to apply a curves adjustment layer that can alter the colors within the selected area. Adjustment layers are non-destructive, meaning they don't permanently alter the original image data.
Steps:
- Create a Curves Adjustment Layer: Creates a curve adjustment layer and clip it to the hair layer to target only the hair.
- Change to the green Channel: Take away green to add magenta
- Add color to hair with curves by adjusting channels and points to taste
Advanced Color Correction: Enhancing Realism with Color Balance Adjustment Layer
To get the best color mix in the hair, use a balance adjustment layer, clipped above curves.
The best settings will differ based on the source material, but playing with these will add the additional color depth for an authentic effect
Blending It In with Opacity: Finding the Sweet Spot
When doing a large color change, things won't look quite right at full opacity, and need to be toned down for realism. It is recommended to put the opacity around 70%-80% to start out. With the right Blend of adjustments and a little transparency, it will end up looking more genuine.
Dark Shades With Bright Hair, A Step Too Far?
As a final WORD, you can go over and adjust the layer mask to clean up around the forhead and the ends of the hair. Also, pay attention to what colors and tones should be most visible in light and shadow, make the hair really take form and create the effect it is just a natural as can be.
