The blow dryer attachment that fits on the nozzle and allows control of air flow to a small area is called:

• A. Concentrator
• B. Diffuser
• C. Nozzle
• D. Vent

Answer: (A)

The key idea is how attachments modify the flow of air from the dryer. The attachment that fits on the nozzle and narrows the air stream to a specific, small area is called a concentrator. By focusing the heat and air to a precise spot, it gives you better control for smoothing, shaping, and directing drying—especially when you want to pull hair taut with a brush or target a curled section for a sleek finish. A diffuser, by contrast, spreads the air over a larger area to dry curls more evenly and reduce frizz, which isn’t about targeted, concentrated airflow. The nozzle itself is the dryer’s tip, not a separate attachment that concentrates airflow, and a vent isn’t an attachment used for this purpose. So the concentrator is the best choice for focused, controlled styling.
