What product should be used to diffuse artificial hair color that a client wants to remove?

Color Remover
Dye-Solvent
Hydrogen Peroxide
Clarifying Shampoo

The correct answer is: Dye-Solvent

The most appropriate product to use for diffusing or removing artificial hair color is a dye-solvent. Dye-solvents are specifically formulated to break down artificial pigments in the hair without causing excessive damage to the hair's structure. These products typically contain ingredients that target the chemical bonds of the dye, effectively lifting the color from the hair. This makes them ideal for clients seeking to lighten or change their hair color without stripping it entirely, allowing for a more controlled and gentle removal process. In comparison, color removers are also effective but are designed more for complete removal rather than diffusing color. Hydrogen peroxide, while useful in lightening hair color, is more of an oxidizing agent and can lead to unwanted lightening or damage if not used carefully. Clarifying shampoos can remove product build-up and help cleanse the hair, but they are not specifically formulated for color removal. Thus, for diffusing artificial hair color, a dye-solvent is the best choice, providing a balance between effectiveness and hair health.
