What is a common contraindication for using hot tools?

Using hot tools on damaged hair or hair that has burns is commonly contraindicated due to the potential for further harm. Hot tools, such as curling irons and straighteners, generate significant heat, which can exacerbate existing damage in the hair shaft. When hair is already compromised, it becomes more susceptible to breakage, split ends, and additional deterioration.

For hair with burns, applying heat can worsen the condition and may even lead to more severe issues such as scalp burns or sensitivities. It's crucial for hairdressers to identify the state of the hair and scalp before using any hot styling tools to ensure the health and safety of their clients. In contrast, while freshly colored hair and excessively oily hair may have their own considerations, using hot tools is not as inherently damaging in those contexts as it is with already damaged or burned hair. Thick hair texture may require different styling techniques but does not generally serve as a contraindication.
