Introduction: Postpartum telogen effluvium (PPTE) is a commonly described entity, but few studies deal with the real incidence and pathogenesis of this claimed common disease.
Objective: To analyze the objective data published and to define the real incidence of the so-called PPTE.
Method: A retrospective review of the published data was conducted.
Results: No statistically significant data were found in any of the papers reviewed, which could support the conclusion that the amount of hair shedding between pregnant and postpartum women is different.
Conclusion: PPTE is not a well-defined entity, and the exact incidence is unknown. From our literature review, we could state that the frequency of PPTE is so low and undefined that we dare say that PPTE does not exist.
