Keywords: Alopecia, Hair Diseases, Hair Follicle


Chronic telogen effluvium can be defined as a hair loss greater than the physiological one (above 150-200 hairs / day) for a period of more than six months, without an evident cause. Although common, it is often underdiagnosed, and raises several questions of a practical nature that the literature still has some difficulties in answering, from its etiopathogenesis to therapy. In this article on Continuing Medical Education, we intend to help answer these questions, reviewing the definition, pathophysiology, clinical / tricoscopic / histological characteristics and the therapy of the chronic telogen effluvium.
