What is one method to create curls in hair using thermal tools?

1. Using a straightener

2. Using a curling iron

3. Using a diffuser

4. Using a brush

The correct answer is: Using a curling iron

Using a curling iron is a well-established method for creating curls in hair through the application of heat. A curling iron consists of a heated barrel that, when hair is wrapped around it, forms spirals or waves depending on the technique used and the size of the barrel. This tool is specifically designed for curling, allowing for different styles by adjusting the direction and size of the curl. In contrast, while a straightener can also create curls, its primary function is to straighten hair, making it less efficient for curling than a dedicated curling iron. A diffuser is typically used to enhance natural curls and waves in hair, particularly when drying; it does not create curls independently. Lastly, using a brush is generally associated with styling for volume or smoothing rather than creating defined curls.
