What is the main function of a hair conditioner?

To strip hair of products and oils
To improve hair's moisture content and manageability
To protect hair from UV rays
To add temporary color to the hair

The correct answer is: To improve hair's moisture content and manageability

The main function of a hair conditioner is to improve the hair's moisture content and manageability. Conditioners are formulated with ingredients that help to hydrate and soften the hair, making it easier to detangle and style. They work by smoothening the cuticle layer of the hair, which can become damaged and rough from various factors like heat styling, environmental elements, and chemical treatments. By restoring moisture, conditioners help prevent breakage and frizz, leading to smoother and healthier-looking hair. In contrast, stripping hair of products and oils is a function typically performed by clarifying shampoos, not conditioners. While some products may offer UV protection, this is not the primary purpose of most conditioners. Similarly, adding temporary color to the hair is a distinct function associated with hair color products or toners, rather than conditioners. Conditioners are specifically designed to enhance moisture and manageability, which is why this is the correct answer.
