Identify one common risk factor associated with improper extension application.

Traction alopecia is the correct answer as it refers to hair loss that occurs due to excessive pulling or tension on the hair follicles. When extensions are applied improperly or too tightly, they can exert undue stress on the natural hair. This tension can lead to inflammation and ultimately damage the hair follicles, which hampers hair growth and can result in permanent hair loss in severe cases.

Recognizing this risk highlights the importance of proper extension application techniques, such as ensuring that the weight of the extensions is evenly distributed and that they are not attached too tightly, which can mitigate the chances of developing traction alopecia.
