1. Attach the concentrator onto the hairdryer.
2. Then use the concentrator to direct the airflow straight at the brush or comb with which you are styling your hair.

The airflow will be more focused and can be directed more precisely to the hair.

The narrower the opening of the nozzle, the faster the airflow and the more precise the styling is.

Concentrator nozzles are used for creating smooth, sleek styles.
