Which technique can help reduce frizz in curly hair?

Applying a smoothing serum is an effective technique to reduce frizz in curly hair. Smoothing serums are typically designed to help seal the hair cuticle, which can be porous and prone to frizz, especially in humid conditions. By creating a barrier against moisture, these serums help to maintain the hair's natural texture while reducing flyaways and frizz.

They often contain silicone or other smoothing agents that can coat the hair strands, adding shine and making the hair feel smoother. Additionally, using a smoothing serum can enhance the definition of curls, improving overall hair appearance without weighing the hair down.

In contrast, methods like blow drying with a round brush can create volume and smoothness, but might not specifically target frizz control for curls. Excessive use of hot tools tends to dry out the hair, potentially worsening frizz over time. Cutting all curls to the same length can lead to a heavy look and may strip away the natural bounce of the curls, making frizz more noticeable rather than reducing it. Thus, applying a smoothing serum directly addresses frizz, making it the most effective choice.
