What are the effects of excessive heat on hair?

Can lead to dryness and damage
Can improve elasticity
Increases shine
Helps retain color

The correct answer is: Can lead to dryness and damage

Excessive heat applied to hair can lead to dryness and damage as it disrupts the hair's natural moisture balance. When hair is exposed to high temperatures, the cuticle (the outer layer of the hair) can become compromised. This results in a loss of moisture, making the hair dry and brittle. The protein structure within the hair can also be altered, which contributes to breakage and split ends. In contrast, options that suggest improvement in elasticity, increased shine, or retention of color are not accurate regarding the effects of excessive heat. Heat can actually diminish elasticity and shine over time due to the structural changes it causes, and it can accelerate color fading by breaking down color molecules. Thus, understanding that excessive heat primarily results in dryness and damage is crucial for maintaining healthy hair.
