When too much heat is applied during hair styling, it can lead to damage and breakage of the hair. Hair is composed of keratin, which is a protein that can be negatively affected by high temperatures. Excessive heat can strip moisture from the hair, weakening its structure and leading to issues such as split ends, brittleness, and overall fragility. This is why professional hairstylists emphasize the importance of using the appropriate heat settings and incorporating heat protectant products before styling. The goal is to style the hair effectively without compromising its health, which highlights the risks associated with overuse of heat tools.
