About





            

                
Stinging nettle root (Urtica dioica) has been studied primarily for benign prostatic hyperplasia, where it demonstrates 5-alpha-reductase and aromatase inhibition. These anti-androgenic properties have led to interest in its potential role in supporting hair health for androgenetic alopecia, though direct clinical hair loss trials are scarce.

            

        

        

        
        
        

            

  
How It Works





            

                
Lignans and polyphenols inhibit 5-alpha-reductase and aromatase; binds sex hormone-binding globulin (SHBG), potentially reducing free DHT at the follicular level.
