Which method is used to curl hair with a curling iron?

The method used to curl hair with a curling iron involves wrapping the hair around the barrel of the curling iron. This technique allows the heat from the iron to penetrate the hair shaft and create a curl. When hair is wrapped around the barrel, it molds to the shape of the iron, which is crucial for producing defined and lasting curls.

In contrast, using a round brush to comb the hair does not create curls; instead, it can help add volume or smoothness to styles. Straightening hair before curling may actually hinder the curling process, as straightened hair may not hold a curl as effectively due to its smoothness and lack of texture. Applying hairspray beforehand can be beneficial for hold, but it is not the primary method for curling; the actual curling occurs through the mechanics of wrapping hair around the barrel of the curling iron.
