Abstract (original English)

Importance Nonscarring alopecia, including androgenetic alopecia and alopecia areata, are common and can negatively impact quality of life. Recent clinical studies have investigated autologous, adipose-derived stromal vascular fraction (SVF) as a potentially beneficial treatment option. Objective To assess the available evidence on the utility and safety of SVF for nonscarring alopecia. Evidence review A systematic review of the literature was performed using MEDLINE (PubMed), Embase, and CENTRAL from inception to November 2020. Included articles were prospective, observational or interventional studies of SVF for nonscarring alopecia in humans. Findings Six studies of 188 patients were identified, including three randomized controlled trials. There were no reported severe adverse events. All studies found improved hair density with SVF compared to control or pre-treatment baseline. One study reported that improvement in hair density varied based on time for follow-up, severity of hair loss, and concentration of adipose-derived stem cells (ADSCs) within the SVF. Two studies reported an increase in hair diameter from baseline, and two studies reported an improvement in hair pull test outcomes. Conclusions and relevance SVF may be safe and effective for nonscarring alopecia in the appropriate patients. Hair loss severity, method of SVF preparation and frequency of treatment, and
