Development and Evaluation of Herbal Hair Gel from Walnut

The rising consumer preference for natural, eco-friendly, and sustainable personal care products has spurred significant interest in herbal formulations that minimize the use of synthetic chemicals. This study focuses on the development and comprehensive evaluation of a herbal hair gel formulated using extracts from Juglans regia (walnut) shells, a byproduct of the walnut processing industry often discarded as waste. The research leverages the rich phytochemical composition of walnut shells, including bioactive compounds such as juglone (5-hydroxy-1,4-naphthoquinone), phenolic acids, flavonoids, tannins, and essential fatty acids like alpha-linolenic acid, to create a multifunctional hair gel that combines styling efficacy with therapeutic benefits for hair and scalp health. The study aligns with the principles of green chemistry and circular bioeconomy by valorizing agricultural waste into a high-value cosmetic product, addressing both environmental sustainability and consumer demand for clean-label hair care solutions
