What type of product is primarily used for adding sheen and manageability to hair?

1. Hair serum

2. Mousse

3. Gel

4. Pomade

The correct answer is: Hair serum

Hair serum is primarily used for adding sheen and manageability to hair due to its lightweight, liquid formulation that often contains silicones or oils. These ingredients help to smooth the hair cuticle, reduce frizz, and enhance shine, making hair look healthier and more polished. Additionally, serums can provide moisture and protection against environmental factors, like humidity and heat from styling tools, contributing to overall hair health and manageability. While other products, such as pomades, gels, and mousses, have their own specific uses—like providing hold, volume, or texture—they do not specifically focus on imparting sheen and enhancing the manageability of hair in the same way that serums do.
