[citation needed] Hair dye stripping is a chemical process involving the application of a sulfur-based product to hair in order to remove deposited color.
Hair dye strippers raise sulfite levels to make hair more porous and reverse the oxidation of color molecules.
[3] Most color depositing dyes use a weak hydrogen peroxide-based developer, or oxidizing agent, so results may not match natural hair color.
Additionally, hair dye stripping products often have a strong, lingering odor reminiscent of rotting eggs due to their sulfuric nature.
Avoid direct skin contact and use in well-ventilated areas.
