Final answer:
Use a low degree of tension when cutting hair with strong growth patterns, to compensate for hair movement when drying. It prevents cutting the hair too short by accounting for natural hair movement.
Step-by-step explanation:
When cutting hair with strong growth patterns, or around the ears, you should use the low degree of tension. Using a low tension is important to compensate for the hair being pushed up when it dries. If you use a higher tension, it can result in the hair being cut too short, as the natural growth pattern of the hair will push it up against gravity once it is dry. To ensure an even and proper length when the hair dries and settles into its natural pattern, low tension helps in mitigating the risk of cutting the hair too short around such tricky areas.
