The Muk Blow 3900-IR Diffuser is designed to soften and diffuse your hair dryer’s airflow, creating defined curls for wavy, curly or permed hair. This diffuser creates beautifully shiny, smooth hair while far-infrared heat penetrates from within, resulting in faster styling with less damage.

The Muk Diffuser is designed to fit the Muk 3900-IR Blow Dryer only.
