The Dyson Airstrait is a revolutionary wet-to-dry hair straightener that uses high-velocity airflow instead of hot plates to straighten and dry hair simultaneously. Powered by the Dyson Hyperdymium motor with a 13-blade impeller spinning at 106,000 rpm, it generates 11.9 liters of air per second through two 1.5mm apertures, creating focused air blades projected at a 45-degree angle to align and straighten hair while drying. Glass bead thermistors regulate airflow temperature up to 30 times per second to prevent heat damage and protect hair's natural shine.

The device features two styling modes: Wet mode with three heat settings (175°F, 230°F, and 285°F) and Dry mode with temperatures of 250°F or 285°F plus a boost function. An LCD color display shows current airflow and temperature settings. The lockable arms enable root drying and volume creation, while an intelligent auto-pause function activates after three seconds of inactivity to conserve energy and prevent overheating. The straightener reduces styling time by approximately 25% compared to traditional drying and straightening routines.

This Costco bundle includes the Dyson Airstrait straightener with four sectioning clips for precise styling, a detangling comb that glides through wet or dry hair with minimal friction, a non-slip heat mat for safe surface placement, and a heat-resistant travel wrap with velvet edging for portability and storage. The bundle provides everything needed for professional-quality hair straightening at home while minimizing heat damage and maintaining hair strength and shine.
