The ghd Duet Blowdry is a 2-in-1 hair dryer brush for people who want a smooth, voluminous blow-dry from wet without juggling a dryer and a round brush. Its stand-out feature is heated bristles arranged in a lattice, combined with an elliptical barrel plate that ghd says creates three times more volume at the root. For short hair that falls flat, that root lift is the main draw.

In its favour
- ghd claims 3x more volume, with the barrel plate shaped to lift hair close to the root.
- The fixed 120°C temperature is checked by sensors 400 times per second.
- Heated bristles in a lattice pattern are designed to glide without tangling.
Good to know
- With a single setting you cannot turn the heat down further for very fragile hair.
- The listed item weight looks like a boxed figure, so the hand-held weight is unclear.
Our take
How it differs from a hot air brush
Most hot air brushes rely only on airflow. The Duet Blowdry adds heated bristles, which ghd says glide through hair without tangling or breakage while boosting shine by 50% and reducing flyaways. The elliptical barrel plate is shaped to build volume close to the root without frizz.
Rated power is 460 W, far lower than a hair dryer, which reflects that the heated bristles share the work with the airflow.
Sensors and humidity resistance
Sensors monitor temperature 400 times per second to prevent heat damage while drying and styling wet hair, according to ghd. The brand also claims up to 50% more humidity resistance and styles that last 24 hours, by respecting hair's natural moisture.
Only one speed and one setting are listed, which keeps operation simple but leaves no adjustment for very fine or very thick hair.
Short hair and practical points
For short hair, the elliptical barrel is the smallest head and works close to the scalp for lift. A comb is listed among included components. ghd lists all, curly, dry, normal and straight hair. The spec table shows 1.49 kg, likely the boxed weight, so the handle weight is not stated on this listing. With no attachments to swap, the routine is simple: towel-dry, section the hair and brush through from root to end. The trade-off is that there is nothing in the box for curls or diffusing, so it works best as a dedicated smoothing and volume tool. Cable length and warranty terms are not given on this page either.
Duet Blowdry against the Dyson Airsmooth and Shark FlexStyle
The Dyson Airsmooth uses airflow and a teardrop head at 1,080 W, with a stated 580 g and universal voltage. The Shark FlexStyle 5-in-1 with a 24 mm curler offers curls and smoothing in a twist-to-dry body. The ghd is the pick for root volume from heated bristles.
Verdict
Choose the ghd Duet Blowdry if you have short to mid-length hair and want a smooth, voluminous blow-dry from wet with heated bristles. If travel and a stated low weight matter, the Dyson Airsmooth fits better, and if you want curls as well, look at the Shark FlexStyle 5-in-1.
