What is the effect of too much heat on hair?

It enhances hair color
It can cause damage and breakage
It improves hair texture
It promotes hair growth

The correct answer is: It can cause damage and breakage

Excessive heat can lead to significant damage and breakage in hair. When hair is exposed to high temperatures from styling tools such as flat irons, curling wands, or even excessive blow-drying, the structural integrity of the hair is compromised. The outer layer of the hair, known as the cuticle, can become rough and raised, which allows moisture to escape and leaves the hair dry and brittle. Over time, this results in split ends and breakage, making the hair appear unhealthy. Additionally, the proteins that give hair its strength and elasticity, particularly keratin, can be denatured by high heat. This damage can lead to long-term issues, requiring more intensive hair care and potential trimming to maintain healthy-looking hair. Therefore, understanding the detrimental effects of too much heat is crucial for maintaining the overall health of hair.
