Development and Evaluation of a Polyherbal Hair Gel for Promoting Hair Growth and Scalp Health

Hair and scalp disorders like dandruff and candidiasis are often linked to microbial infections and poor scalp health, leading to flaking, itching, and hair damage. Conventional treatments may cause side effects and lack holistic care, prompting interest in herbal alternatives. This study developed and evaluated a polyherbal hair gel using 99% Aloe vera gel, flaxseed gel, fenugreek extract (4% diosgenin), hydrolyzed keratin, rosemary essential oil, and cold-pressed jojoba oil. Phytochemical profiling identified key bioactives such as diosgenin, omega-3 fatty acids, polyphenols, and terpenoids. Antimicrobial activity was tested against Staphylococcus aureus, E. coli, and Candida albicans via agar well diffusion. The formulation showed broad-spectrum antimicrobial effects, scalp hydration, and dandruff reduction, with flaxseed lignans, fenugreek, and rosemary contributing to microbial inhibition. Aloe vera and jojoba oil provided moisturization, while keratin aided in hair strengthening. The gel shows promise as a natural treatment for scalp infections and hair care, warranting further clinical validation.
