Identify the problem hairs you want to remove. Don't remove every single hair that sticks out or goes in a slightly different direction than the others. If your picture looks too perfect, viewers will know you spent a lot of time fixing it. Strive for a natural but clean look by identifying just a few hairs that interfere with the image.
Zoom in on the problem area. All photographic software has a zoom feature that will let you enlarge the area you want to focus on. Place your zoom cursor on the hair and click on the zoom feature to keep enlarging until you can see the hair clearly.
Select the clone feature. "Clone" is the term for copying one part of a photograph into another part. When you select the clone feature, a little round target will appear on your photo. You can move this target around with the mouse or your laptop scroller. Move it around a little to get used to how it works.
Identify the background behind the hair in your photograph. This background may be sky, skin or clothing that the hair is in front of. Place your clone target on that background as close to the hair as possible. Click your mouse once or click your left-click bar on your laptop. This will tell the clone target to capture the color of the background.
Move your clone target to the hair. Click once and the clone target will replace the hair in that spot with the color of the background you captured. You can keep moving the target and clicking until you have replaced the hair with the background.
