If you feel your hair is thinning, you may not think now is the time to draw attention to it by trying a new hair color. However, that might be exactly what you need to restore a fuller appearance.
Hair color is a quick and easy way to disguise the look of thinning hair. Permanent hair color contains ammonia, or an ammonia substitute, which makes hair swell, therefore causing it to look thicker.
Experts say one of the best ways to add thickness and volume via color is with soft highlights that are three or four shades lighter than your natural hair color. The shade-on-shade contrast makes hair look far fuller.
