One of the most common and important treatments for cleaning hair is shampooing. Shampoos are primarily used for cleaning hair and the scalp. Nowadays, shampoos are receiving much more attention from consumers compared to soaps. Shampooing is a technique that rinses off the sebum or grease produced by the sebaceous glands, making the hair and scalp dirt and oilfree. In the present scenario, herbal shampoos are considered to perform better and be safer than synthetic shampoos, and they are also gaining more attention from consumers. The main objective of the study was to evaluate synthetic and herbal shampoos. Synthetic shampoos (Dove, Pantene, Clinic Plus, Sun Silk, L'Oréal Paris) and herbal shampoos (Vatika, Kesh King, Chick, Indulekha, Himalaya) were evaluated based on physical appearance, cleansing action, dirt dispersion, wetting action, foaming ability, pH, surface tension, detergency ability, skin sensitization test, eye irritation, and stability studies. The resulting pH of all the formulations was in the range of 7 to 8.5. The evaluation reveals that some have good foaming ability while others do not. Foaming ability should not affect cleansing action. The cleansing action of shampoo should be such that it easily removes grease and dirt from hair. In conclusion, all shampoos are of good quality and can be used safely and effectively by anyone.
