Adjusting SemiColor - Red Brown

Yes, you can adjust the color of SemiColor - Red Brown by adding a black semi-permanent hair color. To achieve a darker or more blackish-brown shade, you can mix SemiColor - Red Brown with SemiColor - Wood Black. Both are semi-permanent hair colors and are designed to be mixed within the same product line.

When mixing, start with a small amount of the black color and gradually add more until you achieve the desired shade. Always perform a strand test on a small, inconspicuous section of hair first to check the color result before applying it to your entire head.

Formulating Hair Dye Based on MSDS

Formulating your own hair dye based solely on the ingredients listed in a Material Safety Data Sheet (MSDS) is generally not recommended. An MSDS provides information about the safety and potential hazards of a substance, but it does not typically contain a complete or precise formulation, including the exact percentages of each ingredient or the necessary manufacturing process.

Hair dye formulation is a complex process that requires specific knowledge of dye chemistry, ingredient compatibility, pH balance, and safety regulations. Simply substituting one color ingredient for another based on an MSDS is unlikely to yield a stable, effective, or safe product. It is crucial to use proper cosmetic formulation guidelines and high-quality, cosmetic-grade ingredients when creating hair dye products.
