What factor can contribute to traction alopecia in hairstyling?

Traction alopecia is a form of hair loss that occurs due to the constant pulling or tension applied to the hair shafts. In hairstyling, certain styles such as tight ponytails, braids, or extensions can create strain on the hair follicles over time. This repetitive pulling can lead to inflammation and damage, ultimately resulting in hair thinning and loss specifically in areas where the tension is greatest.

While factors like insufficient moisture, an unbalanced diet, and environmental pollution can impact overall hair health, they do not directly cause the specific condition of traction alopecia. Thus, the repetitive pulling of hair stands out as the primary contributor in this context, making it the correct response. Understanding the mechanics behind traction alopecia is crucial for hairstylists to avoid styles that can jeopardize the health of their clients' hair.
