Formulation and Evaluation of a Multicomponent Herbal Shampoo for Enhanced Hair and Scalp Health

Abstract

The study focuses on the formulation and evaluation of a novel herbal shampoo as a natural alternative to synthetic commercial products. Synthetic shampoos, though effective, are often associated with adverse effects such as scalp irritation, hair dryness, and hair fall due to the presence of harsh detergents and chemical additives. In response, the present research aimed to develop a safe, eco-friendly, and effective herbal formulation using traditional medicinal plants, including bhringraj, soap nut, shikakai, amla, Senna, hibiscus, aloe vera, lemon juice, rose oil, and gelatin. The shampoo was prepared through Soxhlet extraction and evaluated for its physicochemical and functional properties. Tests performed included physical appearance, pH measurement, per cent solid content, wetting time, dirt dispersion, foaming ability, foam stability, and surface tension analysis. Results revealed that the herbal shampoo had a mildly acidic pH (6.5), consistent with ideal hair care standards. Solid content was measured at 1%, indicating a light formulation. The wetting time was three seconds, demonstrating quick cleansing action, while the dirt dispersion test showed adequate cleansing capacity. Foaming studies confirmed moderate foam stability, and surface tension measurements (30–40 dynes/cm) highlighted vigorous surfactant activity comparable to synthetic shampoos. Overall, the formulated herbal shampoo demonstrated desirable qualities, including effective cleansing, good surface activity, and environmental safety, validating the potential of herbal alternatives in the personal care industry. The findings support consumer preferences for natural, safe, and sustainable products that do not compromise performance or quality.
