Every Hair Dryer Attachment Explained by Experts

Concentrator Nozzle

• What It Is: “A concentrator nozzle is a narrow, flat attachment that directs the airflow from the hair dryer in a focused stream,” says celebrity hairstylist and Tangle Teezer Brand Ambassador, Ryan Pearl. Similarly, hairstylist and owner of Second Floor Salon, Rogerio Cavalcante, adds that concentrator nozzles give the user more control over specific areas of hair, hence why they’re commonly used for blowouts. 
• What It Does: According to Pearl, concentrator nozzles deliver streamlined drying and precise styling with smoothing benefits. “Concentrator nozzles reduce frizz by concentrating heat on specific sections and speeds up the drying process by directing airflow more effectively,” he explains. 
• Who It’s For: Pearl says that all hair types—”especially those needing smoothing and styling”—can benefit from using a concentrator nozzle. “It’s particularly useful for straightening or adding volume to fine or medium hair,” he adds. 
• How to Use It: Concentrator nozzles are easy to use. Attach the nozzle to the hair dryer and direct it to the section of hair you’re drying. Since the nozzle creates space between the dryer and the strands, you can get quite close without the fear of overheating your hair. For best results and the fastest dry time, Pearl suggests using a vented blow dry brush with a concentrator nozzle.

FYI: Concentrator attachments are available in various sizes. Most hair dryers come with at least two options in the box: a classic concentrator and a wider smoothing nozzle. According to Cavalcante, wide nozzles, which offer more airflow, are especially popular for medium to thick hair, as well as damaged hair. “It disperses more air, which helps avoid hair damage since the hot air isn’t as concentrated,” he explains. Pearl tacks onto this, noting that wider nozzles “provide a more even heat distribution, reducing frizz and creating a smoother finish, making it especially good for creating a polished, sleek look.”
