What is the primary function of humectants in hair care products?

Humectants are key ingredients in hair care products due to their ability to attract and retain moisture from the environment or other products. This moisture is essential for maintaining the hair’s hydration levels, which in turn promotes overall health, elasticity, and manageability. By drawing moisture into the hair shaft, humectants help prevent dryness and brittleness, making them particularly beneficial for individuals with dry or damaged hair.

While shine, oil absorption, and volume enhancements are important aspects of hair care, they are not the primary functions of humectants. For example, shine is often achieved through conditioners and oils, oil absorption is typically managed with absorbent powders or specific types of shampoos, and increasing volume usually requires volumizing agents that provide lift or body to the hair. Thus, attracting moisture stands out as the core function of humectants in hair care.
