結論

            
            
There is essentially no reliable scientific evidence supporting horsetail extract for age-related hair thinning — its use is based on tradition rather than clinical research.

            
            
            
    
                
                
  • 
                    
                    Only 1 study exists, and it is a review of misinformation rather than a clinical trial
                
    • 
                
                
  • 
                    
                    No human clinical trials have tested horsetail extract specifically for hair thinning
                
    • 
                
                
  • 
                    
                    Horsetail contains silica, which is traditionally associated with hair and nail health
                
    • 
                
                
  • 
                    
                    Claims about horsetail for hair loss may be overstated relative to the actual evidence
