Fazit

            
            
There is insufficient evidence to determine whether L-Cysteine helps with telogen effluvium — while it is important for hair protein structure, no clinical studies have tested it for this condition.

            
            
            
    
                
                
  • 
                    
                    Only 2 studies available, neither involving human participants with telogen effluvium
                
    • 
                
                
  • 
                    
                    L-Cysteine is a sulfur-containing amino acid essential for keratin production

                    Often included in combination hair supplements, but its individual contribution is unknown
                
    • 
                
                
  • 
                    
                    Dedicated clinical trials are needed to evaluate its specific role in telogen effluvium
