What is the main purpose of shampoo?

The primary purpose of shampoo is to cleanse the hair and scalp. A good shampoo is formulated to remove dirt, oil, sweat, product buildup, and other impurities from the hair and scalp. This cleansing process is essential not only for maintaining hygiene but also for preparing the hair for further treatments, such as conditioning or styling.

Cleansing the scalp is particularly important, as it helps to maintain a healthy environment for hair growth and can prevent issues like dandruff or irritation. While some shampoos may also contain conditioning agents or additional ingredients that can affect the hair's appearance or feel, the primary function remains the removal of unwanted substances to ensure clean, healthy hair and scalp.

Other options like conditioning, styling, and enhancing hair color are secondary functions that may require additional products or treatments to achieve. While conditioners are specifically formulated to improve the hair's texture and moisture, styling products are used to achieve a particular look. Similarly, hair color enhancement requires specific dyes or color treatments beyond the scope of shampoo's primary purpose.
