Fazit

            
            
L-Cysteine has a logical biological connection to hair health as a keratin building block, but there is very little clinical evidence to support its use specifically for nutritional deficiency hair loss.

            
            
            
    
                
                
  • 
                    
                    Only 2 studies exist, with no human clinical trials
                
    • 
                
                
  • 
                    
                    L-Cysteine is a key amino acid in keratin production, providing a biological rationale
                
    • 
                
                
  • 
                    
                    Available evidence is limited to a review article and an in vitro study
                
    • 
                
                
  • 
                    
                    Clinical trials are needed before L-Cysteine can be recommended for hair loss specifically
