What type of hair color is best suited for covering gray hair?

Permanent hair color is the best option for covering gray hair due to its long-lasting properties and ability to effectively penetrate the hair shaft. This type of color typically contains ammonia and a developer, which opens the hair cuticle and allows the color to deposit deeply into the hair. As a result, it provides more complete coverage of gray strands compared to other types of hair color.

Temporary hair colors only coat the outside of the hair and can wash out after a few shampoos, making them less effective for gray coverage. Semi-permanent hair colors might provide better coverage than temporary options but still don’t guarantee complete coverage of resistant gray hair, as they lack the strong chemical components found in permanent hair color. The term "natural hair color" is somewhat ambiguous; if it refers to colors that do not contain any artificial pigments, it wouldn’t be suitable for covering gray hair at all.

In essence, for clients seeking a reliable and lasting solution to gray coverage, permanent hair color is the most effective choice.
