Natural hair dyes without chemicals are botanical products extracted from plants, minerals, or insects that are used to color hair without the inclusion of synthetic chemicals. One common example is henna, a plant-based dye that has been used for centuries to achieve rich, reddish-brown hues.
These natural hair dyes are gaining popularity due to their gentler impact on hair and the environment. They do not contain harsh chemicals that can damage hair or irritate the scalp, and they avoid polluting water sources. Historically, natural hair dyes have been used in various cultures for centuries, with henna being particularly popular in ancient Egypt and henna.
