Eflúvio telógeno: causas, diagnóstico e tratamento

Abstract

Telogen effluvium is a non-scarring alopecia characterized by diffuse hair loss resulting from the premature entry of follicles into the telogen phase of the hair cycle. This study aimed to review, through an integrative approach, the main causes, diagnostic methods, and treatment strategies for telogen effluvium, in order to support more effective clinical and aesthetic practices. The review included 27 articles published between 2016 and 2024, selected from the databases Scientific Electronic Library Online (SCIELO) and U.S. National Library of Medicine (PUBMED). Telogen effluvium may be triggered by stress, hormonal changes, systemic diseases, medications, and nutritional deficiencies. Diagnosis involves detailed anamnesis, laboratory tests, and complementary techniques such as phototrichogram, trichoscopy, and biopsy. Therapeutic options include elimination of the causal agent, vitamin supplementation, and interventions such as platelet-rich plasma (PRP), microneedling, mesotherapy, and low-level laser therapy, which stimulate hair growth and strengthen hair structure. An individualized and multidisciplinary approach is essential to restore hair health and minimize psychosocial impacts on patients.
