North Dakota Cosmetology Practice Exam

Which of the following can cause hair breakage?

1. Regular trims and conditioning

2. Coloring every month

3. Over-processing, lack of moisture, and mechanical damage from styling tools

4. Using natural hair products

The correct answer is: Over-processing, lack of moisture, and mechanical damage from styling tools

Hair breakage can occur due to a variety of factors, and the correct choice highlights the primary causes that commonly lead to this issue. Over-processing refers to the damage done by chemical treatments, such as perming, relaxing, or frequent coloring, which can weaken hair structure. Lack of moisture indicates that hair is not adequately hydrated, making it brittle and more prone to breaking. Mechanical damage is associated with the excessive use of styling tools, like curling irons, straighteners, and even rough towel drying, which can put stress on the hair shaft. In contrast, regular trims and conditioning are protective measures that help to maintain hair health by removing split ends and adding moisture. Frequent coloring without proper care could contribute to breakage, but it is not solely the act of coloring that is harmful—it's the frequency combined with inadequate moisture and care. Lastly, using natural hair products is typically beneficial and helps reduce the risk of breakage rather than causing it. Overall, the correct answer effectively encompasses the critical factors that lead to hair breakage in a comprehensive manner.
