Product Overview

Transform your hair styling routine with the Shark FlexStyle Air Styling And Drying System in Stone. This clever 2-in-1 device works as both a powerful hair dryer and versatile multi-styler for all hair types - straight, wavy, curly or coily. Just twist to switch between drying and styling modes. The system measures temperatures 1000 times per second, minimising heat damage while you style. With 4 heat settings, 3 airflow speeds and a cool shot, you'll have complete control. The Coanda Technology uses two air streams to attract hair and tame frizz for a smooth, glossy finish. Weighing just 0.66kg without attachments, it's comfortable to use, and the 2.8m cord gives you plenty of movement. The package includes a styling concentrator, oval brush, two 3.5cm auto-wrap curlers for different directions, and a soft storage bag. Powered by 1650 watts, it delivers fast drying and precise styling in one compact device. Model HD421SL comes with a 2 year manufacturer's warranty.

    Affordable Results

    I use my shark Flexstyle everyday. It’s easy to set up and very easy to use. The results are great both for straightening and curling. I love it and the price was budget friendly.
