Background: Telogen effluvium (TE) is one of the most common forms of nonscarring alopecia. TE typically presents as sudden diffuse shedding of hair, and generally occurs 3–4 months after a triggering event such as physiological or psychological stress, certain medications, or hormonal changes. Despite the high prevalence of TE, no standardized clinical guidelines for the management of this condition currently exist. Objective: To address the lack of standard clinical guidelines for the management of TE, a multidisciplinary panel of dermatologists, dermatology advanced practice providers, and primary care providers convened to evaluate current evidence related to the treatment of TE. Methods: The primary research team, composed of 13 individuals, completed a comprehensive literature review of TE treatment. Then an expert panel conducted 2 rounds of article review, assessing each article based on the Strength of Recommendation Taxonomy (SORT) criteria and formulating consensus statements based on this data. An expert panel of 20 clinicians then evaluated the statements utilizing a structured eDelphi consensus process. Results: A total of 18 consensus statements regarding treatment recommendations for TE were reviewed by the expert panel. Of these, 3 statements addressed acute TE, while 15 focused on chronic TE. The panel evaluated each statement through open forum discussion, followed by voting and modification using the eDelphi methodology. Ultimately, 16 statements reached consensus following 2 rounds of the eDelphi survey. Conclusion: The self-limiting nature of acute TE warrants patient education, but no specific therapies were found to improve outcomes compared with placebo. While there is a gap in quality research regarding chronic TE treatment, current evidence suggests that topical minoxidil, vitamin D supplementation, and platelet-rich plasma may provide benefit in chronic TE based on individual clinical judgement.

Study Design: A panel of 13 clinicians with experience in dermatology and primary care was assembled to review literature regarding the diagnostic workup of scarring and nonscarring alopecias. The literature for review included clinical trials, meta-analyses, systematic reviews, and previously published guidelines from the last 10 years. After review, the panel drafted a list of consensus statements and then voted on these statements using a modified eDelphi method in order to verify the validity and clarity of each statement. Objective: Our objective, as a panel, was to formulate a clear set of guidelines in the workup of various forms of hair loss by a systematic review of clinical data and literature on the matter. Background: Hair loss is a common and frustrating medical concern for patients worldwide and accounts for significant health care utilization and cost. Moreover, hair loss may present as a symptom of an underlying medical condition requiring attention and treatment. Results: After review, the panel reached a total of 22 consensus statements regarding recommendations for diagnostic testing in the setting of hair loss, 17 of those statements focused on nonscarring alopecias, and 5 statements directed toward scarring alopecias. The statements were evaluated by members of the panel and voted on through a modified eDelphi method and discussed in an open forum. Conclusion: The panel’s review revealed that the diagnostic laboratories and/or scalp biopsy should be considered to varying degrees depending on the type of hair loss at presentation. If there is concern for a scarring process, a biopsy should be strongly considered, while serum laboratory work may be of little benefit. In nonscarring alopecias including alopecia areata, telogen effluvium, and androgenetic alopecia, the literature supports ordering certain serologic tests based on the type of hair loss at presentation.
