The most commonly used hair color for covering gray hair is permanent hair color. This type of hair color contains a chemical formula that allows it to penetrate the hair shaft, resulting in a long-lasting change. Unlike temporary or semi-permanent hair color, which may shift or wash out over time, permanent hair color provides a more durable solution for those looking to fully cover gray strands.

Permanent hair color typically contains ammonia or a similar agent that helps open the hair cuticle, enabling the color to develop within the hair strand. This makes it effective in completely covering gray, as it provides complete coverage and long-lasting results, ensuring that the color will not fade quickly and will maintain its vibrancy throughout the life of the color.

Semi-permanent options may not provide the full coverage that some individuals desire, as they usually last through several washes and can fade over time, making them less effective for people looking to maintain a uniform color that fully conceals gray hair. Temporary hair colors wash out much more quickly and are best for those seeking a short-term change rather than a lasting fix.

Highlighting products are designed to brighten and add dimension to the hair rather than to cover gray, making them unsuitable for this specific purpose. Permanent hair color remains the go-to choice
