Serum is the product typically used for smoothing and controlling frizz in hair due to its specific formulation designed to address these concerns. Hair serums often contain silicones or oils, which help to coat the hair strands, providing a sleek appearance and reducing the rough texture that can lead to frizz. By creating a barrier against humidity and environmental factors, serums help to maintain hair's smoothness and shine throughout the day.

In contrast, gel is primarily used for styling, providing hold and definition but not necessarily for taming frizz. Pomade can offer some shine and hold but may not effectively control frizz, especially in humid conditions. Hairspray is used for setting hairstyles in place rather than for smoothing, and it does not typically contain the nourishing ingredients found in serums. Thus, serum stands out as the best choice for addressing frizz while also enhancing overall hair health and appearance.
