2. To enhance hair color

3. To moisturize and detangle the hair

4. To protect against UV rays

The correct answer is: To moisturize and detangle the hair

The primary function of a conditioner is to moisturize and detangle the hair. Conditioners are formulated with ingredients that help to improve the texture and manageability of the hair after cleansing. They work by penetrating the hair shaft and adding moisture, thus making the strands softer and easier to comb or brush through. This is particularly important for reducing breakage and maintaining overall hair health, as moisturized hair is less prone to damage. Additionally, conditioners often contain emulsifiers and fatty substances that help to smooth the hair cuticle, which can further assist in detangling. This smoothing action is essential for preventing knots and split ends, contributing to a more polished and healthy appearance. While conditioners may offer additional benefits, such as some protection against UV rays or color enhancement, their primary role is centered around hydration and detangling.
