Question: 1 / 400

What can excessive heat do to hair during styling?

Strengthen the hair structure

Moisturize the hair

Cause damage and breakage

Excessive heat during styling can lead to damage and breakage of hair. When hair is exposed to high temperatures from tools such as flat irons, curling wands, or blow dryers, the protective layer of the hair can be compromised, leading to weakened strands. This can result in dryness, split ends, and an overall lack of elasticity, making the hair more prone to breakage.

Hair is made up of proteins, primarily keratin, and when subjected to intense heat, these proteins can denature or change their structure. This denaturation is what makes the hair lose its natural strength and resilience. In extreme cases, consistent high-heat styling can result in irreversible damage, leaving the hair looking dull and lifeless.

Maintaining a balanced approach to heat styling, including the use of heat protectant products and lower temperature settings, can help mitigate these negative effects and preserve the integrity of the hair.
