Conclusão

            
            
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

                    Clinical trials are needed before L-Cysteine can be recommended for hair loss specifically
