Formulation and Evaluation of Antidandruff Shampoo of Costus Speciosus

Dandruff is a common scalp disorder characterized by excessive shedding of dead skin cells and is often associated with fungal infection, particularly Malassezia species. Herbal formulations have gained importance due to their safety, efficacy, and minimal side effects. The present study aimed to formulate and evaluate an antidandruff shampoo containing extract of Costus speciosus. Costus speciosus possesses antifungal, anti-inflammatory, and antimicrobial properties which may help reduce dandruff and improve scalp health. The shampoo was formulated using suitable surfactants, preservatives, and conditioning agents and evaluated for various physicochemical parameters such as pH, viscosity, foamability, foam stability, dirt dispersion, surface tension, and stability. The formulated shampoo exhibited acceptable characteristics and may serve as an effective herbal antidandruff preparation.
