Covering gray hair is a technique that conceals hair that has lost its natural pigmentation. Gray hair occurs as a natural part of the aging process and is caused by a decrease in the production of melanin, a pigment that gives hair its color.
Covering gray hair can help individuals maintain a more youthful appearance, enhance self-confidence, and comply with professional or social standards. One significant historical development in hair coloring is the invention of synthetic hair dyes in the late 19th century, which revolutionized the field and made it more accessible.
