What is the role of a shampoo in hair care?

1. To cleanse the hair and scalp of dirt, oil, and product buildup

2. To add shine and moisture to the hair

3. To style the hair into a desired shape

4. To chemically straighten the hair

The correct answer is: To cleanse the hair and scalp of dirt, oil, and product buildup

The primary role of shampoo in hair care is to cleanse the hair and scalp of dirt, oil, and product buildup. Shampoos are formulated with surfactants that create lather and help to lift away these impurities. This cleansing action is essential for maintaining scalp health, as a clean scalp can reduce the risk of irritation and promote healthy hair growth. Furthermore, regular cleansing helps to prepare the hair for subsequent treatments, such as conditioning and styling, by ensuring that the hair is free from residues that could hinder the effectiveness of these products. While other products may focus on adding shine or moisture, or may be used for styling or chemical processes, these are not the fundamental purposes of shampoo. Therefore, understanding shampoo’s primary purpose as a cleanser is crucial in establishing a solid foundation for effective hair care routines.
