What's the difference between a curling iron and a curling brush?

The main differences between a curling iron and a curling brush lie in their design, functionality, and styling results:

Curling Irons
Design: Typically features a cylindrical barrel that heats up.
Functionality: Used to wrap sections of hair around the barrel to create curls or waves.
Styling Results: Can produce defined, bouncy curls or loose waves, depending on the barrel size and technique.
Skill Level: Requires some technique to use effectively, especially for different curl styles.

Curling Brush (or Hot Air Brush)
Design: Combines a brush and a heating element, often with bristles to help grip hair.
Functionality: Used to style hair while drying, providing volume and curl simultaneously.
Styling Results: Creates softer, more natural waves and volume; ideal for smoothing and styling in one step.
Skill Level: Generally easier to use, especially for beginners, as it combines brushing and curling.

Summary
In essence, a curling iron is more specialized for creating defined curls, while a curling brush offers a more versatile, user-friendly option for styling and adding volume.
