What is the common term for hair that has lost its natural pigments?

Gray hair is the common term used to describe hair that has lost its natural pigments, leading to a lack of color that is often associated with aging. As people grow older, the production of melanin, which gives hair its color, decreases, resulting in hair that appears gray or white.

The term "colored hair" generally refers to hair that has been dyed or treated with color, rather than hair that has naturally lost its pigment. "Bright hair" is not a standard term used to describe the process or condition of hair losing its dyes or pigments. "Bleached hair" refers specifically to hair that has been chemically treated to remove its color, usually resulting in a lighter shade, but it does not imply that the hair has lost its natural pigmentation in the same way that aging does. Thus, gray hair is the most accurate term for this condition, reflecting the natural process of aging that affects hair pigmentation.
