What is the effect of applying excessive heat during styling?

Applying excessive heat during styling can lead to hair damage and breakage. This occurs because the hair is made up of a protein called keratin, which can be structurally altered by high temperatures. When heat is applied beyond a certain threshold, it can strip moisture from the hair, causing it to become dry, brittle, and more susceptible to breakage.

Moreover, heat can weaken the cuticle, the outer layer of the hair shaft, leading to further damage and a lackluster appearance. Prolonged exposure to excessive heat styling tools, such as flat irons and curling wands, can create irreversible damage over time. Therefore, practicing heat management through appropriate temperature settings and using heat protectants is vital for maintaining hair health while styling. This understanding underscores the importance of moderation and care in styling practices to avoid detrimental effects on hair integrity.
