## Description

For anyone who wants to dry, curl, and style with one tool, the Shark FlexStyle Next-Gen IonCurl brings those steps together in an ion-powered air styler. Coanda airflow wraps hair around the curlers, while interchangeable attachments support different styling tasks. Want curls that fall in different directions on each side? The left and right barrels are designed to do just that. Scalp Shield Mode and adjustable heat settings add practical control as you style.

## Getting the most from it
Use the FlexStyle as a dryer, then switch to an attachment for curling or shaping. The two Coanda Auto-Wrap Curlers work in opposite directions: the left barrel curls counterclockwise and the right barrel clockwise. That makes it easier to create curls that fall naturally on either side without manually wrapping hair around a traditional curling iron. For finishing, the FrizzFighter High Shine Polisher, Oval Brush, and Styling Concentrator offer different ways to smooth, shape, or direct airflow.

Scalp Shield Mode lowers the temperature to a cooler setting while drying, and the four heat levels let you choose a setting for your styling routine. If you want to pause mid-style, double-tap the cool-shot button to activate AirSet, holding the button gives a burst of cool air. Together, these controls make the tool useful for moving between drying, shaping, and setting a style in one routine.

## Benefits
The central advantage is having drying and styling functions in one tool, rather than setting up a separate dryer and curling tool. Coanda airflow helps wrap hair around the barrels, while ion-powered airflow is designed to help control frizz and support faster drying. The manufacturer describes the styling approach as avoiding heat damage, and the FrizzFighter attachment is designed to add shine as a finishing step.

Buyers describe the dryer as effective and easy to use, and some say it dries hair faster or leaves it smoother. Feedback on hair performance is mixed, however, with some customers mentioning brush bristles shedding. These are individual experiences, while the interchangeable attachments and airflow features define how the styler is designed to work.

## Before you decide
What attachments come with the styler? The listed set includes Coanda Auto-Wrap Curlers, a FrizzFighter High Shine Polisher, an Oval Brush, and a Styling Concentrator, covering curling, polishing, brushing, and directed airflow.

How do the curlers wrap hair? Coanda airflow does the wrapping. The left barrel curls counterclockwise and the right barrel clockwise, providing opposite curl directions for the two sides of your head.

What do Scalp Shield Mode and AirSet do? Scalp Shield Mode switches to a cooler setting while drying. Double-tapping the cool-shot button activates AirSet to pause airflow mid-style, holding the button provides a burst of cool air.

## When it makes sense
It makes sense if you want one styling tool for drying, curls, and finishing, with attachments for more than one look. The 8-foot cord supports movement during styling, while the range of heat settings and the cooler Scalp Shield option give you ways to adjust the routine. For people who prefer an air-based multi-styler over assembling separate drying and curling tools, the FlexStyle’s combination of curl barrels, brush, polisher, and concentrator makes it a practical fit for everyday styling routines.
