The Dyson Airstrait in Bright Nickel and Bright Copper (HT01) is Dyson's most pioneering hair styling technology — the only straightener in the world powered by the Dyson Hyperdymium motor that uses only high-pressure, temperature-controlled airflow to simultaneously dry and straighten hair without hot plates, without extreme heat and without the heat damage, frizz and reduced shine that conventional flat iron straighteners cause through direct contact between superheated metal plates and the hair's keratin and cortex structure. The Bright Nickel and Bright Copper colourway is one of Dyson's most premium Airstrait finishes — the polished nickel silver body panels with bright copper accent details reflecting the Dyson design philosophy of engineering-forward aesthetics in premium materials, a warm metallic palette that pairs equally naturally with a bathroom shelf, a dressing table or a travel bag. The fundamental engineering principle behind the Airstrait is the replacement of mechanical heat-plate contact with aerodynamic tension — air heated to a precisely controlled temperature is projected downwards at a 45° angle through the hair tress as it passes between the Airstrait's arms, creating exactly enough tension to align the hair's cuticle scales in the smooth, flat orientation that produces a straight style, without the physical compression, extreme localised heat or repeated mechanical stress that conventional straighteners apply to each section of hair with each pass. The result is a styling process that independently tested studies confirm achieves 2× the shine of air drying, a 66% reduction in frizz and flyaways compared to natural drying, and a result that 94% of users in Dyson's consumer surveys agreed left their hair looking and feeling soft — without the brittle, overly-processed texture that heat-damaged hair develops over months of conventional flat iron use.

The Dyson Hyperdymium motor — the same fundamental motor architecture that powers Dyson's Supersonic hair dryer and Airwrap styler — spins a 13-blade impeller at up to 106,000 RPM to propel 11.9 litres of air through the Airstrait per second, generating up to 3.6 kPa of air pressure — the physical force that makes airflow-based straightening mechanically possible at styling speeds comparable to conventional hot-plate straighteners. The glass-bead thermistors located inside both arms of the Airstrait measure actual airflow temperature at the point of exit onto the hair up to 30 times per second — not the temperature of the heating element, but the temperature of the air touching the hair — making continuous micro-adjustments to the heating output to maintain the set temperature precisely regardless of how fast the user moves the tool, preventing the temperature spikes that occur when a slower pass allows the heating element to oversupply heat to the airstream. This is the heat control architecture that physically prevents heat damage during normal use: the temperature that reaches the hair is regulated in real time rather than set and left to vary with user technique. The Wet Mode provides three preset temperature options — 80°C for fine or colour-treated hair, 110°C for medium or wavy hair and 140°C for thick, coarse or highly textured hair — each optimised for taking freshly washed or damp hair to a finished straight style in a single pass through each section. The Dry Mode for refreshing between washes provides the same temperature range with an additional Boost setting at maximum heat for maximum styling impact on fully dry hair. The Cool Mode sets the style in place by encouraging the hydrogen bonds in the hair to stabilise in their new aligned position after the warm airflow has reorganised them.

The Intuitive Airflow system uses sensors in the arms to detect when hair is positioned between them, automatically dropping to low airflow when the arms are empty — reducing noise during between-section pauses, saving power and preventing unnecessary heat delivery to the scalp or surrounding surfaces. The Auto-Pause function stops airflow entirely after three seconds of inactivity and restarts immediately when the device is moved again. The Arms Lock function closes the arms and operates the Airstrait as a pre-drying tool for the roots and mid-lengths before beginning the straightening passes section by section — a practical workflow feature that Dyson stylists designed into the Airstrait after testing found that pre-drying with locked arms significantly reduces total session time by removing excess moisture before the directional airflow straightening begins. The LCD colour screen displays the current mode, temperature setting and airflow speed throughout the session for clear, at-a-glance reference without interrupting the styling flow. Negative ion generation reduces static charge in the hair during styling for a smoother, frizz-free finish. The PRCD safety plug incorporates the residual current device electronics directly in the plug body — an additional safety element specifically engineered for the Airstrait's direct wet-to-dry function, reducing the weight and size of the handset itself while providing the safety protection required for use of a powered hair tool around moisture. The Bright Nickel/Bright Copper Airstrait is supplied with a velvet heat-resistant mat for safe placement during and after styling. 2-year warranty.
