This has a barrel-shaped centre which heats up when you blow dry hair with it. So, when hair is wrapped around that heated part, even thick and unruly locks get easily tamed. Depending on the size of the barrel, these brushes also add curl, volume, and waves to your hair, with the smallest diameters proving the tightest curls, larger ones helping make hair wavy and lift hair at the crown.
