Question: 1 / 400

What happens when hair is excessively exposed to heat?

It becomes healthier

It changes color

It becomes brittle and damaged

When hair is excessively exposed to heat, it becomes brittle and damaged due to the breakdown of the protein structure in the hair. Hair is made primarily of keratin, a protein that can be altered and weakened by high temperatures. Overheating can strip moisture from the hair, leading to dryness, split ends, and an overall unhealthy appearance. This damage manifests as brittleness, making the hair more prone to breakage and loss of elasticity. Maintaining a proper temperature during styling and using heat protection products are essential to preserving the integrity of the hair. Taking these precautions helps to combat the damaging effects of heat, ensuring that hair retains its strength and shine.
