In this video, we learn how to change hair color in Photoshop CS3 and CS4. First, open up your image and zoom in on the hair. From here, you will click on the selection tool with a circle to select your image. Now, make sure this is the perfect size for the entire image. Right click and make sure it's sized out right. Now, select the hair and a red marker will appear. Select the whole surface of the hair, and as you get to the short hair use a smaller circle tool, don't worry about the smallest pieces. After this, you will go to layer, new fill layer, and solid color. Click this, then a pop up will appear where you can change the mode to soft light. Now, choose the color that you would like and you're done!
