TLDR The conclusion is that three signs can help diagnose hair loss after it happens, potentially avoiding more invasive tests.
The document presents five cases of acute telogen effluvium (TE) resolution, highlighting a triad of clinical signs that can aid in diagnosing TE after the active phase: frontal fringe, temporal rarefaction, and occipital fringe. These signs are proposed as the "acute telogen effluvium triad after resolution." The study emphasizes the difficulty of diagnosing TE post-actively, especially when the pull test is negative, and differentiates TE from other conditions like alopecia areata and traction alopecia. The cases involve patients who experienced hair loss due to various stressors such as pregnancy, weight loss, a car accident, and severe infection, with subsequent spontaneous hair regrowth. The document suggests that recognizing the triad can help avoid more invasive diagnostic procedures like scalp biopsies, as the triad indicates recent or ongoing TE. The study does not specify the number of people in the study beyond the five cases presented.
