What is the consequence of applying excessive heat to hair during styling?

Applying excessive heat to hair during styling can lead to significant damage, resulting in dryness and split ends. High temperatures can strip the hair of its natural moisture, leading to a loss of elasticity and strength. This damage manifests as brittle hair that is prone to breakage. Additionally, excessive heat can cause the hair cuticle to become rough, giving the appearance of dullness rather than shine. In severe cases, the internal structure of the hair can be compromised, making it fragile and more susceptible to further damage.

While enhanced shine and volume might be desired effects of certain styling techniques, they are usually not sustainable when excessive heat is applied. Instead, such practices can ultimately lead to an overall decline in hair health. Strengthening the hair structure is not achievable through heat; rather, it often results in the opposite effect, where weakened strands are unable to hold their shape or resilience.
