Cyclophosphamide was the most frequently used chemotherapeutic agent, while peripheral blood stem cell transplantation was the most common transplantation method. Trichoscopy showed short vellus hairs and hair diameter diversity. Histopathologically, the proportion of vellus hair and that of catagen\/telogen hair increased. Treatment primarily targeting hair follicle miniaturization improved hair volume in 52.9% of cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Main pathology is considered the hair miniaturization rather than inflammation\u2010mediated change in the chronic phase of hair loss.
