Question: 1 / 400

What is the effect of using too much heat on hair during styling?

It can enhance the hairstyle

It makes hair more manageable

It can cause damage and breakage

Using excessive heat on hair during styling can lead to significant damage and breakage. Hair is made up of a protein called keratin, which can be compromised when exposed to high temperatures. Over time, this can result in dry, brittle hair that is prone to splitting and breaking.

When heated beyond safe limits, the hydrogen bonds within the hair structure can be altered, leading to texture changes and potentially irreversible damage. This includes a loss of moisture, natural oils, and elasticity, resulting in hair that is not only unsightly but also difficult to manage.

In contrast, enhancing the hairstyle, making hair more manageable, or promoting hair growth are outcomes that could be associated with appropriate heat styling techniques, but excessive heat tends to move the results in the opposite direction, ultimately harming the hair instead.
