Dyson Airstrait HT01 Straightener (Blue/Copper)

Dyson Airstrait HT01 Straightener (Blue/Copper)

The Dyson Airstrait HT01 Straightener (Blue/Copper) straightens hair with air rather than hot plates. In this finish, deep Prussian Blue arms are paired with Rich Copper accents, the colourway Dyson lists for the model this listing carries in Blue and Copper. Inside, a Dyson Hyperdymium motor drives a focused jet of heated air through the section of hair held between the arms, drying and straightening at the same time. Because there are no plates pressing heat directly into the hair, Dyson designed the machine to style without the extreme heat damage associated with conventional straighteners used as directed.

The practical change is to the routine itself. Instead of rough-drying hair fully and then straightening it in a second pass with a second tool, the Airstrait takes hair from wet to a finished, natural straight style in one step. A separate Dry mode then handles refreshes and touch-ups between washes. Airflow is projected downwards at a 45 degree angle, which creates the tension needed to align the hair while it dries, giving a smooth finish that keeps movement rather than a flat, pressed result.

Key features

• No hot plates: Heated airflow straightens the hair without plate contact or clamping pressure, and Dyson rates the machine to style with no heat damage when used as directed.
• Wet to dry in one tool: Wet mode dries and straightens simultaneously at three pre-set temperatures of 80, 100 and 115 degrees Celsius, removing the separate blow-dry step.
• Dry mode with Boost: Refresh styles from dry at 100 or 130 degrees Celsius, with an optional Boost mode for maximum styling impact on resistant sections.
• Hyperdymium motor airflow: A 13-blade impeller spins at up to 106,000 rpm, propelling 11.9 litres of air per second at up to 3.6 kPa of pressure, enough to straighten hair as it dries.
• Intelligent heat control: Glass bead thermistors in the machine arms measure and regulate airflow temperature 16 times a second, holding the set temperature steady through each pass.
• Intuitive airflow and auto-pause: The machine senses when hair is between the arms and drops to low airflow when it is not, and it pauses automatically after three seconds of inactivity until you move it again.
• LCD colour screen: A high-definition display shows the styling mode, airflow and temperature settings at a glance while you work.
• Lock feature and cold setting: Slide the button to lock the arms together for gentle pre-drying and root volume, and finish sections with the cool airflow setting to set the style.

How the airflow straightens

Two arms channel the heated air into a pair of downward jets angled at 45 degrees. As a section passes through, those jets dry the hair under tension at a controlled temperature, breaking and reforming the hair’s hydrogen bonds in the straight position in the same way a blow-dry with a brush does, but with the airflow doing the work of both brush and dryer. Negative ions in the airflow help reduce static, so the finish stays smooth rather than flyaway. Because the heat arrives through air instead of a plate in direct contact, the temperature the hair experiences is both lower than a typical flat iron setting and actively regulated throughout.

Controls and daily use

Mode, temperature and airflow are set with simple controls and confirmed on the LCD screen, and the machine remembers how you work: airflow rises when hair is detected between the arms and eases off when you set it down, which keeps noise and energy use down between sections. Auto-pause engages after three seconds without movement and restarts the moment you pick the machine up and move it. With the arms locked, the Airstrait works as a gentle pre-dryer to lift roots before styling, a useful step for finer hair that needs volume before it needs straightening.

Power and finish

The Airstrait is a corded machine rated at 1600 W, drawing its airflow from the Hyperdymium motor in the handle, and it is engineered for the range of hair types, from fine to coarse, using its Wet and Dry mode temperatures rather than a single fixed heat. The Blue and Copper finish combines the deep blue body with copper detailing on the accents, a pairing that makes the tool recognisable on a dressing table and, for many buyers, the version chosen when the machine is bought as a gift.

If your current routine is a dryer in one hand and a flat iron in the other, the Airstrait HT01 in Blue and Copper replaces both with a single pass from wet hair to a straight, natural finish, at regulated temperatures and without a hot plate ever touching your hair.
