Postpartum Telogen Effluvium Unmasking Additional Latent Hair Loss Disorders

We sought to detect additional underlying hair loss disorders in patients with postpartum telogen effluvium.

We completed clinical and dermoscopic evaluations on 200 female participants experiencing postpartum hair loss.

9.5 percent of patients were diagnosed with telogen effluvium (TE), 56.0 percent patients were diagnosed with TE with androgenetic alopecia (AGA), 6.5 percent patients were diagnosed with TE and TA, and 28.0 percent patients were diagnosed with TE, AGA, and TA. In the central area, patients with TE displayed upright regrowing hair and single pilosebaceous unit in 100 percent and 94.7 percent of patients, respectively. While patients with TE and AGA, displayed upright regrowing hair, single pilosebaceous unit, and hair diameter diversity greater than 20 percent. In patients diagnosed with TE and TA, the trichoscopic findings were similar in the TE group to the patients diagnosed with TE, AGA, and TA were also similar to the patients with TE and AGA. Regarding the area of traction, there was no difference observed between the patients with TE and TA and patients with TE, AGA, and TA. The frequent findings were hair diameter diversity, empty follicles, and vellus hair.

Postpartum TE may be associated with other hair loss disorders. Awareness of this is critical to appropriate diagnosis and treatment.
