Red Seal Hairstylist Practice Exam

What is a common reason for hair breakage?

1. Low humidity

2. Excessive heat styling

3. Frequent trims

4. Daily shampooing

The correct answer is: Excessive heat styling

Excessive heat styling is a common reason for hair breakage because it can damage the hair's structure. When tools such as flat irons, curling wands, and blow dryers are used frequently at high temperatures, the moisture content in the hair diminishes, leading to dryness and brittleness. This makes the hair more susceptible to snapping or breaking, especially if proper heat protection products are not used. In this context, while low humidity can contribute to dryness, it does not directly cause the same level of immediate damage as heat styling. Frequent trims, on the other hand, are beneficial as they help remove split ends and promote healthier hair growth, and daily shampooing, if done correctly with hydrating products, does not inherently lead to breakage. Thus, the impact of excessive heat styling on hair structure clearly outlines why it is a significant contributor to breakage.
