The Subrina Professional hydrogen peroxide lotion is a key component when using hair dye or bleaching agents. It is designed to work in conjunction with the color or bleaching agent to initiate the chemical reaction that brings about the desired transformation of the hair. The strength of the oxidizing agent (usually measured in volumes) can affect the level of lift or deposit of color. It is recommended to follow the specific instructions for the hair dye or bleaching product you are using to achieve the best results.
