High\u2010frequency ultrasound (HFUS) has been used to assess hair follicle morphology and scalp vascularization. The objectives of the study are to evaluate HFUS characteristics of patients with FFA and, secondarily, to study the usefulness of HFUS in assessing disease activity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Prospective study between January and June 2018.

Frontal hair growth area showed reduced follicle number and miniaturization.
