D

結論

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
