Creating barrel curls requires a curling iron, as it is specifically designed to wrap sections of hair around a heated barrel, resulting in defined, bouncy curls. The barrel’s design allows for uniform heat distribution, which is essential for effectively shaping and setting the hair into curls.

While other tools, such as flat irons and hair dryers, have their specific uses in hairstyling, they do not provide the same capability for creating classic barrel curls. A flat iron can create waves or sleek styles but doesn’t achieve the round, voluminous curls. A hair dryer is typically used for drying or styling hair with brushes or volumizers but does not curl hair on its own. Similarly, a round brush is great for adding volume and smoothing out hair when blow-drying but cannot produce curls without additional heat from a curling iron. Therefore, the best tool for achieving barrel curls is indeed the curling iron.
