How can excessive heat affect hair?

Excessive heat can significantly impact hair health by causing damage and breakage. When hair is exposed to high temperatures from styling tools such as flat irons, curling wands, or blow dryers, the heat can strip moisture from the hair shaft. This leads to a breakdown of the cuticle, which is the protective outer layer of the hair. As the cuticle becomes damaged, hair loses its strength and elasticity, making it more prone to snapping or splitting.

Furthermore, recurring exposure to excessive heat can exacerbate these effects, leading to a condition commonly known as heat damage, characterized by dryness, frizziness, and an overall unhealthy appearance. While some styling techniques may temporarily enhance shine or alter the hair's appearance, the long-term consequence of using high heat is detrimental to the overall integrity of the hair. Maintaining adequate moisture and employing heat protection products can help mitigate some of the damage caused by excessive heat.
