Does excessive shampooing promote or strip the fatty oily sebum needed for hair softness?

Excessive shampooing strips the fatty, oily sebum that is essential for maintaining hair softness and health. Sebum is a natural oil produced by the sebaceous glands in the scalp, and it serves several important functions. It helps to moisturize and protect the hair, contributes to its shine, and prevents dryness and brittleness. When shampoo is used too frequently or in excessive amounts, it can remove not only dirt and impurities but also this important oil. As a result, the hair can become dry, frizzy, and more prone to damage. Proper hair care involves balancing cleanliness with moisture retention, and understanding the effects of shampooing habits is crucial for maintaining healthy hair.
