What is the primary benefit of using a round brush during blow-drying?

• A. It colors the hair while drying
• B. It increases curl tightness without heat
• C. It helps direct airflow to smooth the cuticles during blow-drying
• D. It strengthens hair strands

Answer: (C)

Directing the airflow to smooth the cuticles during blow-drying is the main benefit. When you wrap a section around the round brush and pull it downward while applying heat, the heat and tension help the cuticle scales lie flat. A smooth cuticle surface reflects light better and resists frizz, giving a sleeker, shinier finish. The round brush also helps shape the hair, but the essential advantage in this context is guiding the air and heat to smooth the hair shaft. Coloring, shrinking curl without heat, or strengthening strands aren’t the primary outcomes of using a round brush during blow-drying.
