What method involves temporarily straightening hair using heat?

The method that involves temporarily straightening hair using heat is known as thermal hair straightening. This technique utilizes heated styling tools, such as flat irons or hot combs, to alter the structure of the hair temporarily. When the hair is heated, the bonds within the hair strands change, allowing the hair to become smooth and straight. Once the heat is removed, the hair will generally return to its natural texture, making this method a non-permanent solution to achieve straight hair.

Understanding the nature of thermal hair straightening is crucial because it emphasizes the importance of heat protection and proper technique to avoid potential damage to the hair. This method is particularly popular because it provides significant styling versatility, allowing individuals to switch between straight and textured looks as desired.

Other methods listed, such as cascade curl and scrunch waves, focus more on creating curls or textured styles rather than straightening hair. The silk press is a specific technique that also uses heat to achieve straight, sleek hair, but it is often associated with a more refined process that involves additional steps for smoother results.
