Herbal cosmetics have gained significant importance in recent years due to increasing awareness regarding the harmful effects of synthetic cosmetic products. Hair dyes are widely used cosmetic preparations for coloring hair and improving appearance; however, synthetic hair dyes contain chemicals such as ammonia, paraphenylenediamine, and hydrogen peroxide that may cause scalp irritation, hair damage, allergic reactions, and other toxic effects. Therefore, there is a growing demand for safe, natural, and eco-friendly herbal alternatives. The present study focuses on the formulation and evaluation of an herbal hair dye using Eclipta alba as the major active ingredient. Eclipta alba, commonly known as Bhringraj, is a well-known medicinal herb traditionally used in Ayurveda for promoting hair growth, preventing premature greying, and improving scalp health.The herbal hair dye was prepared using Eclipta alba along with other natural ingredients possessing coloring and conditioning properties.

The prepared formulation showed satisfactory coloring effects along with good consistency, smooth texture, and acceptable stability. The herbal ingredients also provided conditioning and nourishing effects to the hair and scalp. The formulation was found to be safe, non-irritating, and suitable for topical application.The study concluded that Eclipta alba possesses excellent potential as a natural ingredient in herbal hair dye formulations. Herbal hair dyes can serve as safer and economical alternatives to synthetic dyes while providing additional therapeutic benefits.
