The Bottom Line

            
            
Ginseng shows early promise for alopecia areata with all studies reporting positive findings, but the evidence is still limited to a small number of studies and requires more clinical research to confirm.

            
            
            
    
                
                
  • 
                    
                    All 4 studies report positive effects, but the total evidence base is small

                    Korean red ginseng has been specifically tested in one controlled clinical trial for alopecia areata

                    Ginsenosides may support hair growth through cell proliferation and immune modulation
                
    • 
                
                
  • 
                    
                    More and larger clinical trials are needed before strong recommendations can be made
