Open a digital photo of yourself or someone else in Adobe Photoshop or another graphics program on your computer. Zoom into the photo and select the "Clone brush" or "Clone stamp" tool. Select a portion of the side of the person's face or head to clone an area with no hair. Position your cursor onto the person's head and start brushing over the hair to remove it.
Use the "Healing brush" tool instead, which is easier. Again, select a portion of the head or skin where there is no hair, pressing "Alt" while you press your left mouse button to select. Then, brush over the hair on the head. This will erase the hair but have no effect on the shape of the head, and the skin color will appear in place of the hair.
Continue with the above steps and work your way lower if the person has long hair. If the hair is long, copy a portion of the person's shirt or the background to remove the hair with the "healing brush" tool.
