GHD’s Duet Blowdry is designed to measure the surface temperature of the device 400 times per second to maintain consistent heat throughout use. This rate exceeds that of the company’s Chronos Max hair straightener, which checks the temperature 250 times per second. The Duet Blowdry features a single heat setting of 248 degrees Fahrenheit, which GHD considers an optimal low styling temperature. Although this temperature is lower compared to most heat tools like straighteners and curling irons, it is relatively higher compared to blow-dry brushes, which typically offer heat levels closer to 200 degrees Fahrenheit, with some, like the Revlon, reaching up to 240 degrees.
The Duet Blowdry also claims to minimize heat damage, though the extent of protection may depend on an individual’s hair delicacy and the use of heat protectants. GHD notes that while it is described as a wet-to-dry brush, users should wait until their hair is 80 percent dry before shaping it. The tool can aid in achieving this dryness level prior to styling, although it may not function optimally on very wet hair.
Whether the tool’s heat damage claims hold true, it is noted that the blowout experience is impressive, providing significant volume without excessive wind effect and reducing flyaways. The results also appear to last longer, maintaining a fresh look on subsequent days without losing volume or becoming oily, issues often encountered with other styling sessions.
For some users, the price of the Duet Blowdry might be justified by these benefits despite it being double the price of other blow-dry brushes such as those from Drybar or T3. However, the singular tool offering could be a limitation, especially when considered against similarly priced options like the Shark FlexStyle or FlexFusion, which come with multiple attachments. Nonetheless, the Duet Blowdry’s ability to deliver a satisfactory blowout without the need for a follow-up with a flat iron is significant for some users, who find the results exceptional for their everyday styling needs.
