Chemical-free hair dye, also known as natural hair dye, refers to hair colorants derived from plants, minerals, or other natural sources without the use of synthetic chemicals. An example of chemical-free hair dye is henna, a plant-based dye used for centuries to color hair and enhance its texture.
Chemical-free hair dyes provide several benefits, such as being gentler on the hair and scalp, minimizing the risk of allergic reactions and skin irritations. Historically, chemical-free hair dyes have been used as a safer and more sustainable alternative to synthetic hair dyes, which contain harsh chemicals that can damage hair and the environment.
