Which type of styling product is most effective for adding texture to hair?

Texturizing spray is specifically designed to enhance the natural texture of hair, providing it with body and volume without weighing it down. This type of product often contains lightweight ingredients that can help define waves or curls and add a tousled, lived-in look. It's particularly useful for styling purposes as it allows for manipulation and versatility, making it easier to create styles that appear effortlessly textured.

Other products like hairspray are primarily designed for hold and finishing styles rather than adding texture. Gel can provide a strong hold and definition, but it may create a crunchy or stiff feeling that doesn't promote a natural texture. Mousse is also used for volume and can add some texture but is generally less specialized than texturizing spray when it comes to enhancing and defining hair's natural texture.
