Previous fat grafting and hair transplantation using the FUE technique on scalp scars: Update

We developed a narrative literature review on the association of fat grafting and hair transplantation using the Follicular Unit Extraction (FUE) technique in scalp scars. Data were collected from studies found in Medline, Lilacs, and IBECS databases. Bibliographical records of several authors who researched mesenchymal cells in adipose tissue were cited, describing the techniques used.The conclusion was that the two-stage hair transplantation technique, with previous fat transplantation, is effective, according to the reviewed articles.
