Question: 1 / 400

What is a potential effect of excessive heat on hair?

Increased shine and texture

Damage, dryness, and potential breakage

Excessive heat can have detrimental effects on hair, leading to damage, dryness, and potential breakage. When hair is exposed to high temperatures, such as from styling tools like flat irons, curling wands, or blow dryers, it can strip the hair of its natural moisture. This drying effect weakens the hair's structural integrity, making it more prone to frizz and split ends. Over time, repeated exposure to excessive heat can compromise the protein structure of the hair, resulting in brittleness and increased likelihood of breakage.

In contrast, the other options imply beneficial effects of heat on hair, which is misleading. While some might expect that heat could enhance shine, texture, or smoothness, these results are typically only temporary and depend greatly on the hair's initial health and the protective measures taken, such as using heat protectants.
