Which term refers to a substance capable of dissolving another substance?

The term that refers to a substance capable of dissolving another substance is a solvent. In the context of chemistry and haircoloring, the solvent is typically the liquid component that allows other substances, such as color pigments, to dissolve and create a homogeneous solution.

In haircoloring, the solvent is essential for ensuring that the color can evenly penetrate the hair. This is crucial because an effective haircolor application relies on the solvent effectively interacting with the hair's structure and the color molecules.

Understanding this concept is vital for anyone working in beauty and cosmetology, as it influences the effectiveness of haircolor products and formulations.
