Red Seal Cosmetology Practice Exam

Where should you test the hair for elasticity and porosity?

1. Several areas of the head

2. Only at the tips

3. At the scalp

4. In a singular, uniform section

The correct answer is: Several areas of the head

When testing hair for elasticity and porosity, it is important to test various areas of the head. Each section of hair may have different characteristics, so testing multiple areas will provide a more accurate understanding of the hair's overall elasticity and porosity levels. Testing only at the tips could potentially provide misleading results, as the ends of hair may be more damaged or less porous compared to the rest of the hair. Similarly, testing solely at the scalp may not give a complete picture as the roots of hair may have different properties than the rest of the hair. Testing in a singular, uniform section may also not be as accurate as it may not account for any variations in the hair's characteristics. Therefore, the best approach is to test several areas of the head to get a comprehensive understanding of the hair's elasticity and porosity.
