Shampoo belongs to both cosmetics and daily necessities.
Cosmetics refer to the products used for smearing, spraying, wiping or other similar ways to clean, beautify, protect, modify, change the appearance or adjust the body odor. Shampoo, as a product used to clean and protect hair, meets the definition of cosmetics.
At the same time, shampoo is also a daily product, because it is one of the necessary cleaning products in our daily life and needs to be used every day. Like other daily necessities, the main function of shampoo is to meet the needs of daily life, not for special purposes such as beauty.
Therefore, shampoo can be classified as both cosmetics and daily necessities.
