Formulation and Evaluation of Herbal Hair Dyes from Tannin Producing Plants: A Substitute for Chemical Hair Dye
TLDR Herbal hair dyes from tannin-rich plants are effective and safer than synthetic dyes.
In a study from March 31, 2021, researchers explored the use of tannin-producing plants as a basis for creating natural herbal hair dyes, presenting them as a safer alternative to the potentially harmful synthetic dyes commonly found in the market. The study focused on plants known for their tannin content, including Henna (Lawsonia inermis), Brinjal (Solanum melongena), Pomegranate (Punica granatum), Ridge guard (Luffa acutangular Roxb), and Raw Banana (Musa acuminata). The herbal hair dye formulation was evaluated and found to effectively color hair without causing damage, hair loss, or skin irritation, unlike its synthetic and semi-synthetic counterparts. The document suggests that these plant-based dyes, which also include well-known substances like chamomile and turmeric, could be mixed with distilled water and applied to hair as a safe and permanent coloring method.
