Which type of color treatment provides long-lasting results for covering gray hair?

Permanent color treatment is specifically designed for long-lasting results, especially when it comes to covering gray hair. This type of color penetrates deeply into the hair shaft, providing a lasting effect that typically endures until the hair grows out or is cut. The formulation involves a chemical reaction with the hair's natural pigment, enabling complete coverage of gray strands.

Semi-permanent colors, while also effective, generally wash out over time and may not provide the same level of gray coverage or longevity as permanent color. Temporary color is even more fleeting, often lasting only a few shampoos and typically used for short-term changes or fashion colors. Frosting, on the other hand, is a highlighting technique rather than a coloring treatment aimed at gray coverage. Therefore, for individuals seeking a dependable solution to maintain their color and conceal gray hair effectively, permanent color is the ideal choice.
