What effect does excessive heat use have on hair?

Excessive heat use can significantly alter the structure of the hair, leading to damage. When hair is exposed to high temperatures, it can cause the cuticle layer, which is the hair's outer protective covering, to become brittle and dry. This damage can manifest as split ends, breakage, and an overall loss of elasticity. Additionally, the protein structure within the hair can break down, leading to weakened strands that may appear dull and lifeless.

While one might wish for enhanced growth, vibrancy, or strength as a result of heat, the reality is that frequent and unregulated heat application generally leads to adverse effects that compromise hair health. Thus, using heat styling tools responsibly and in moderation is crucial to maintaining the integrity and appearance of hair.
