The best choice for controlling frizz in hair is a smoothing serum. Smoothing serums are specifically formulated to coat the hair shaft, providing a barrier against humidity and helping to tame flyaways and frizz. These products often contain silicones and other smoothing agents that help to seal the cuticle of the hair, making it appear shinier and more polished while reducing texture disruption from environmental factors.

In contrast, moisturizing creams primarily focus on hydration and might help with frizz to some extent, but they do not provide the targeted smoothing effect that serums offer. Leave-in conditioners are designed to add moisture and can improve the overall health of the hair, which may indirectly reduce some frizz, but their main purpose is not frizz control. Texturizing sprays are aimed at creating volume and texture rather than smoothing out the hair, making them less effective for controlling frizz. Therefore, while some of the other options provide benefits related to hair health, a smoothing serum is the most effective product specifically for controlling frizz.
