Question: 1 / 495

What does the hair growth percentage in the anagen phase depend on?

Location of the body

The percentage of hair growth in the anagen phase is significantly influenced by the location of the body. Different areas of the body have distinct hair growth patterns and cycles due to variations in hair follicle characteristics. For instance, hair on the scalp typically has a longer anagen phase, leading to longer hair growth, while body hair, such as on the arms or legs, usually has a shorter anagen phase, resulting in shorter hair growth.

This anatomical and physiological variation is crucial for laser technicians to understand when assessing hair for laser treatments, as it affects treatment planning and expectations for hair reduction. While age, diet, and hormonal balance can impact hair growth in general, it's the specific body location that determines the proportion of hair actively growing in the anagen phase, making it the most relevant factor in this context.
