What type of product is used to enhance the curl in curly hair during styling?

The use of gel or curl-enhancing cream is ideal for enhancing the curl in curly hair during styling because these products are specifically formulated to define and hold curls. They provide moisture and support, allowing curls to maintain their shape and bounce without becoming crunchy or weighed down. These products often contain ingredients that help to enhance the natural texture of curly hair, providing definition and reducing frizz.

In contrast, a smoothing serum focuses more on reducing frizz and providing shine, which might not contribute to the definition of curls. Hair spray is typically used to provide hold and set styles rather than enhance the curl itself. Dry shampoo is designed to absorb oil and refresh hair between washes, so it does not have properties aimed at styling or enhancing curls. Therefore, gel or curl-enhancing cream is the most suitable product for achieving vibrant and well-defined curls.
