What condition is described as hair loss through repetitive and excessive pulling or stretching of the hair?

The condition characterized by hair loss due to repetitive and excessive pulling or stretching of the hair is traction alopecia. This occurs primarily as a result of hairstyles that put tension on the hair follicles, such as tight ponytails, braids, or extensions. Over time, this constant strain can damage the hair roots, leading to thinning hair or bald spots, particularly around the areas that experience the most tension. Understanding the mechanisms behind traction alopecia is critical for both prevention and treatment, emphasizing the importance of adopting gentler hair styling practices to protect hair health.

Conditions like alopecia areata involve autoimmune factors that lead to sudden hair loss in patches, while androgenetic alopecia is linked to genetics and hormonal changes, typically resulting in a predictable pattern of hair loss. Telogen effluvium, on the other hand, relates to a temporary increase in hair shedding due to various stressors. Each of these conditions has distinct causes and characteristics, differentiating them from traction alopecia, which is specifically induced by external mechanical stress on the hair.
