What are the effects of excessive heat on hair?

Excessive heat can have significant detrimental effects on hair, leading to damage, dryness, and breakage. When hair is exposed to high temperatures—such as from styling tools like flat irons, curling wands, or blow dryers—it can compromise the hair's natural moisture balance. This results in dryness as the moisture is evaporated, leaving the hair more prone to damage.

The structure of the hair can also be adversely affected. The heat can weaken the protein bonds that give hair its strength and integrity. Over time, this damage manifests as breakage, split ends, and an overall reduction in hair health. The hair may appear dull and lifeless, lacking the shine and softness that indicate healthy strands.

In contrast, other choices refer to beneficial aspects of hair health, like growth, shine, softness, elasticity, strength, and volume, which are typically not associated with excessive heat exposure. Instead, they represent qualities that healthy hair should have. Thus, recognizing the importance of proper temperature control during styling is crucial for maintaining hair health and avoiding the adverse effects of excessive heat.
