Diluted H O (between 1.9% and 12%) mixed into a solution with aqueous ammonia aniline(color molecule) and a coupler, has been used to color human hair. It can also be mixed with powder or cream bleach compounds, most notably potassium chloride. Bleaching hair follicles does not destroy or remove color molecule or melanocytes. Bleaching compounds work to drive wedges between color molecules or melanocyte's allowing more visible light to pass through the hair shaft. The chemical's bleaching property lends its name to the phrase " peroxide blonde ". Hydrogen peroxide is also used for tooth whitening. It may be found in most whitening toothpastes. Hydrogen peroxide has shown positive results involving teeth lightness and chroma shade parameters. It works by oxidizing colored pigments onto the enamel where the shade of the tooth may become lighter. Hydrogen peroxide may be mixed with baking soda and salt to make a homemade toothpaste.
