A modern thermal iron and ___________ are all you need to give your client curls.

A modern thermal iron and a hard rubber comb are essential tools for creating curls in a client’s hair. The hard rubber comb is specifically effective because it withstands heat well, allowing you to section and manage the hair without the risk of melting or warping that can occur with other materials. When using a thermal iron to curl hair, the comb helps to remove tangles and provide smooth sections, ensuring that each strand can be evenly curled for a polished finish.

While a metal comb may conduct heat, it is not ideal to use with a thermal iron, as the heat can transfer through the comb and potentially burn the scalp or damage the hair. A plastic brush, while useful in other hairstyling tasks, would not provide the same level of control and precision needed for curling. A towel, although practical for drying and protecting surfaces, does not contribute to the curling process itself and therefore is not a necessary tool in this context.
