Normal Shampoo

Shampoo was developed to replace soap for cleansing scalp and hair by removing unwanted sebum, dandruff, environmental dust, and residues of hair care products. Most of the dirt including sebum are water insoluble and cannot be effectively removed by water alone. Therefore, a shampoo containing a combination of surfactants is necessary. The content of surfactants in a shampoo is typically between 10% and 20% . Ideally, a good shampoo should produce a voluminous lather and effectively cleanse the hair and scalp and should be easily rinsed out with water, leaving the hair soft, lustrous, and moisturized. The product should not adversely affect the scalp and hands or cause irritation to the eyes, particularly when children and baby formulations are considered.
