A Polyherbal Approach to Hair Care: Development and Evaluation of a Solid Shampoo Bar

The study developed and evaluated a polyherbal solid shampoo bar using natural ingredients like Amla, Soapnut, Hibiscus, and Aloe vera, aiming to offer an eco-friendly and cost-effective alternative to conventional hair care products. The shampoo bar was tested for various physicochemical properties, including pH, foamability, cleansing efficiency, hardness, and stability. Results showed that the formulation had good lathering capacity, an acceptable pH for scalp application, and stability under different storage conditions, suggesting it as an effective, safe, and sustainable option for hair care.
