Hair dye strippers raise sulfite levels to make hair more porous and reverse the oxidation of color molecules. This breaks the bonds dyes form between one another and the hair shaft that were formed by oxidizing small hair color intermediates, [1] shrinking the molecules and allowing hair color to be washed out of the hair.

Minoxidil sulfate is formed from minoxidil via sulfotransferase enzymes, with the predominant enzyme responsible, at least in hair follicles, being SULT1A1. [1] [2] Minoxidil sulfate acts as a potassium channel opener, among other actions, and has vasodilating, hypotensive, and trichogenic or hypertrichotic (hair growth-promoting) effects.

Other skin lighteners during the 16th century containing mercury and acidic ingredients were more harsh, and would remove the superficial epidermis of the skin or stop the production of melanin altogether. [1] Some sources state that the faithful application of ceruse by many was a result of the side effects caused by its lead compounds.
Early humans evolved dark skin color, as an adaptation to a loss of body hair that increased the effects of UV radiation. Before the development of hairlessness, early humans might have had light skin underneath their fur, similar to that found in other primates . [ 67 ]
The results showed improvements in hair shine, volume, and appearance, and nail shine and appearance. [30] An Italian study evaluated the effects of a nutraceutical composed of MSM, hyaluronic acid, and L-carnosine. The results from RCT showed broad improvements in facial skin hydration and elasticity, as well as decreased sebaceous secretions ...
Bleaching the hair is a gradual process and different colors may be achieved dependent on the original hair color, application time, and strength of the product used. Applied on black hair, the hair will change its color to brown, red, orange, orange-yellow, yellow, and finally pale yellow. [19]
Colloidal sulfur (sulfur colloidale) is an extremely fine sulfur powder prepared by repeated precipitation, first from polysulfides with protein and then from a slightly alkaline solution with ethanol or acetone. It has a greyish-white colour. Colloidal solutions in water are milky, and bluish when viewed against the light due to the Tyndall ...
