Smoothing serum is designed specifically to reduce frizz in hair. This type of product generally contains silicones or other emollients that create a barrier around the hair strands, helping to seal in moisture and prevent the cuticle from lifting, which is what leads to frizz. By applying a smoothing serum, hair appears shinier and more manageable, making it less prone to becoming frizzy in humid conditions.

Conditioner can help maintain moisture, which is beneficial for dry hair that may be prone to frizz, but it doesn't directly target frizz control in the same way a smoothing serum does. Texturizing spray primarily adds texture to hair and may not address frizz effectively. Volumizing mousse focuses on adding body and volume, and while it may improve hair's appearance, it does not combat frizz specifically. Thus, smoothing serum is the most effective choice for reducing frizz.
