Red Seal Cosmetology Practice Exam

How much can wet hair with normal elasticity stretch up to?

1. 25%

2. 50%

3. 75%

4. 100%

The correct answer is: 50%

Wet hair with normal elasticity can stretch up to 50% of its original length. This is because when hair is wet, the hydrogen bonds that hold the hair together are temporarily broken, making the hair more malleable and able to stretch. However, stretching the hair more than 50% can cause damage and breakage to the hair strands. Options A, C, and D are incorrect because they exceed the maximum stretching capacity of wet hair with normal elasticity. It is important to not over-stretch wet hair in order to maintain its health and prevent breakage.
