Did ancient people use animal hide as a colorant for hair?

Yes, ancient people sometimes used animal hides as a colorant for hair. They would extract dyes from the fats and oils found in animal skins or use the hides themselves to create pigments. These natural colorants were often derived from the processes of curing and tanning, which could impart various shades to hair. Additionally, other natural materials like plants and minerals were more commonly used, but animal-based dyes did play a role in hair coloring practices.
