Hair plays a significant role in the physical appearance and psychological confidence of individuals. Increasing exposure to pollution, stress, unhealthy dietary habits, and excessive use of synthetic cosmetic products has resulted in several hair-related problems such as dandruff, hair fall, dryness, scalp irritation, split ends, and premature greying. Herbal cosmetics have gained considerable attention due to their safety, effectiveness, eco-friendly nature, and minimal side effects compared to synthetic products. The present research work focuses on the development and evaluation of a polyherbal multipurpose hair mask prepared using natural herbal ingredients, including shikakai, reetha powder, amla powder, hibiscus, flaxseed, aloe vera, curry leaves, brahmi powder, and neem powder. The formulation was prepared by shade drying, pulverizing, sieving, and blending the herbal ingredients in suitable proportions. The prepared hair mask was evaluated for organoleptic properties, pH, spreadability, washability, stability, skin irritation, and overall performance. The results demonstrated that the formulation possessed acceptable physicochemical properties and showed beneficial effects such as improved hair texture, reduction in dandruff, scalp nourishment, conditioning, and strengthening of hair follicles. The study concluded that the prepared polyherbal hair mask is safe, economical, stable, and effective for maintaining healthy hair and scalp conditions. The herbal ingredients exhibited synergistic activity, making the formulation a promising alternative to synthetic hair care products.
