How do heat tools affect hair when not used correctly?

The way heat tools interact with hair is significant, particularly concerning their potential for causing damage when not used correctly. Heat tools, such as curling irons, straighteners, and blow dryers, exert high temperatures on the hair, and when improperly utilized—whether through excessive heat, prolonged exposure, or inadequate preparation of the hair—this can lead to structural changes in the hair.

When heat is applied too intensely, the protective outer layer of the hair, known as the cuticle, can become compromised. This results in the hair becoming dry, brittle, and more susceptible to breakage. Additionally, the internal structure of the hair may be altered, leading to weakened strands that can frizz or split. The cumulative effect of repeated misuse of heat styling tools can significantly degrade the overall health of the hair.

It's important to recognize that while heat styling can be used to achieve desired aesthetics, it requires knowledge and appropriate techniques to mitigate potential damage. Options that propose benefits such as enhancing strength, providing moisture, or creating styles without harm do not account for the risks associated with improper use of heat tools, making them misleading in this context.
