Using excessive heat on hair can lead to dryness and breakage, which occurs because heat strips the hair of its natural moisture and proteins. When hair is exposed to high temperatures from styling tools like straighteners and curling irons, it can damage the cuticle, the outer protective layer of the hair. This damage diminishes the hair's ability to retain moisture, resulting in a brittle texture.

When hair becomes overly dry, it loses flexibility and can start to break easily, leading to split ends and overall deterioration in hair health. Maintaining the health of hair often involves using heat protection products and adopting a balanced heat styling routine to mitigate these risks. Understanding this relationship is essential for anyone working in cosmetology, as they often advise clients on best practices for hair care and styling.
