Air Keratin technology for hair protection
Air Keratin technology combines an advanced keratin plate surface, direct airflow and intelligent temperature control up to 1000× per second. According to laboratory tests, the device can preserve 100% of the hair's keratin*. The combination of these elements supports controlled styling for both drying and straightening.
Simultaneous drying and straightening
The Rowenta Air KeraStraight 3-in-1 combines a powerful airflow with heated plates to dry and straighten your hair at the same time. This means you can achieve your morning hairstyle in a single step without needing a separate hairdryer and straightener. The result is straight, smooth hair with fewer steps in your daily styling routine.
Up to twice as soft and shiny hair
The built-in ioniser releases millions of ions, helping to reduce static electricity and flyaways. This makes your hairstyle look sleeker and gives your hair a smoother appearance with up to 2× more shine**. Ionisation complements your styling with care focused on a well-groomed look.
Gentle straightening for wet hair
The wet hair mode lets you dry and straighten hair simultaneously at temperatures of 80°C, 110°C or 140°C. Your hair gradually gets a naturally straight and smooth look without needing to finish drying with a separate appliance first.
Fast drying from root to tip
The high-speed digital motor creates an airflow of up to 160km/h. This powerful airflow helps to dry hair efficiently along its entire length, supporting a faster daily routine. The appliance thus combines the power needed for drying with a straightening function.
A smooth, straight style for up to 24 hours
The dry hair mode is used to finish your style and achieve a perfectly straight look. Choose from temperatures of 150°C, 180°C and 210°C, depending on your hair's needs and the desired result. The smooth effect can last for up to 24 hours**.
Settings for different hair types
Six plate temperature settings, three airflow speeds and a cool shot function let you customise your styling to your current needs. The wet hair mode uses lower temperatures for simultaneous drying and straightening, while the dry hair mode offers higher temperatures for final styling.
Comfortable to use when styling
The compact design and ergonomic shape make it easy to handle while styling your hair. A 360° swivel cord helps prevent the cord from getting in the way while you work and contributes to more comfortable movement around your head. The appliance is also easy to store after use.
