Function and attributes Function: Acts as both a nozzle and a diffuser by gathering air at the dryer outlet and dispersing it over a wider area to control airflow intensity and direction. Size and fit: Designed specifically for outer barrel diameters of 4.354.50 cm 1.711.77 inch. Verify your dryer measurement before . Material: Molded black plastic that is lightweight, durable, and suitable for repeated use. Performance: Reduces concentrated heat and force on hair strands by dispersing air, which supports gentler drying and more even styling results. Practical use scenarios Diffusing curls and waves: Attach the diffuser to soften airflow and help define natural curl pattern with less frizz and less disruption to shape. Gentle drying for long or fine hair: Use the diffuser to lower direct airflow pressure when drying long or fragile hair to avoid excessive lift and tangling. Quick touchups and smoothing: Use the nozzle setting to direct airflow for targeted smoothing around the roots or ends during styling sessions. What to check before use Measure your dryer barrel outer diameter to confirm it falls within 4.354.50 cm 1.711.77 inch. Ensure the attachment is firmly seated on the dryer before operation. Use with appropriate heat and speed settings for your hair type and styling goals. This nozzle and diffuser attachment provides a practical option for controlling dryer airflow, protecting style shape, and making daily styling more efficient.
