What is the primary function of the concentrator attachment on a blow dryer?

• A. Increase air volume
• B. Increase heat
• C. Focus airflow on a small area
• D. Humidify air

Answer: (C)

Concentrated airflow is all about precision. The attachment narrows and directs the hot air so you can target a small section of hair with a brush, guiding the flow along the strand to dry and shape it more efficiently. This focused stream helps the hair lay smoothly, reduce frizz, and achieve a sleeker finish because you’re controlling where the heat goes rather than blasting a wide plume of air everywhere. It doesn’t increase the amount of air produced or the heat set by the dryer, and it doesn’t add humidity to the hair; those factors come from the dryer’s settings and how you use them.
