Which product is often used to add shine to hair?

Hair oil is specifically designed to enhance the appearance of hair by adding moisture and a reflective shine. It typically contains various nourishing ingredients such as natural oils that can penetrate the hair shaft and help to smooth the cuticle, resulting in a glossy finish. Many hair oils not only provide shine but also offer additional benefits, such as reducing frizz, providing heat protection, and improving overall hair health.

In contrast, texturizing spray is primarily used to provide volume and texture, giving hair a more tousled look rather than focusing on shine. Hairspray is mainly used to hold styles in place, which does not typically contribute to shine but rather helps in maintaining the desired shape of a hairstyle. Dry shampoo functions by absorbing excess oil at the scalp and providing a cleaner appearance, but it does not add shine to the hair itself. Thus, hair oil stands out as the most effective choice for achieving a shiny finish in hair care.
