Attachments and spare parts for the Supersonic hair dryer. A 6-inch oversized diffuser widens the bowl for faster drying on curls and coils, a clip-on smoothing nozzle turns the dryer into a finishing tool, and a split-design outer filter cage fits over the cable without unplugging the dryer.
Matching the part to your model
- 6-inch diffuser — fits Supersonic HD01, HD02, HD03, HD04, HD08, HD15 and HD16. Strong magnetic mount, long prongs that lift roots.
- Smoothing nozzle 967715-01 — fits HD01, HD02 and HD03 only. Twist-lock, no adaptor needed.
- Outer filter cage — fits HD01, HD03, HD07 and HD08. Split design clips over the cable, so no need to open the dryer.
The model number is printed on the handle of every Supersonic dryer. Check it against the list above before ordering — misfit is the most common reason an attachment comes back. None of the parts on this page fit the Supersonic r series, which uses a different mount.
