Humectants are known to perform which function?

Humectants are a class of substances commonly used in hair care products due to their ability to attract and retain moisture. They work by drawing water molecules from the environment into the hair, helping to maintain hydration and prevent dryness. This property is essential for achieving healthy, well-moisturized hair, as it enhances the overall appearance and manageability.

The function of absorbing moisture and promoting water retention is particularly beneficial for individuals with dry or curly hair types, as these hair types are often more prone to moisture loss. By incorporating humectants into hair care routines, users can achieve softer, shinier, and more pliable hair.

The other options present functions that do not accurately describe the role of humectants. While some hair care products may aim to remove oils or strengthen hair bonds, these processes involve different ingredients and mechanisms. Additionally, providing color to hair pertains to dyes and pigments, which are not related to the moisture-retaining properties of humectants.
