Alberta Written Barber Practice Exam

Wet hair is able to be stretched to what percent of its length?

1. 20% to 30%

2. 30% to 40%

3. 40% to 50%

4. 50% to 60%

The correct answer is: 40% to 50%

Wet hair has unique properties that allow it to stretch significantly more than dry hair. When hair is wet, the hydrogen bonds in the protein structure break, enabling the hair strands to become more pliable and stretchable. Research indicates that wet hair can be stretched to approximately 40% to 50% of its original length without causing damage. This elasticity is critical for barbers to understand, as it influences how they cut, style, and treat hair. Choosing the range of 40% to 50% reflects a clear understanding of hair's behavior when wet, crucial for making informed decisions about techniques and products in barbering practices. The ability to stretch hair properly helps in achieving various styles, minimizing the risk of breakage or damage during styling procedures.
