What do the ancient records show from where hair coloring matter came from?

Ancient records indicate that hair coloring substances were derived from natural sources such as plants, minerals, and animal products. For example, Egyptians used henna and various plant extracts for dyeing hair, while the Greeks and Romans often employed mixtures of ash and other materials. In China, historical texts reveal the use of indigo and other botanical dyes. These early practices laid the foundation for modern hair coloring techniques.
