"In a paper regarding evidence based guidelines in the treatment of alopecia for both women and men (Blumeyer et al.), various amino acids are mentioned with a special mention for cysteine. Cysteine is considered to be one of the main factors involved in hair growth.
The group that also followed the dietary supplement had a 50% increase in hair growth.
The paper cites a study (Morganti et al.) where there was a significant mean change of total hair count in both male and female patients after a treatment containing cysteine.
The participants had to take an oral supplement that contained cysteine, copper, zinc and histidine 4 times a day for 50 weeks and the treatment group had remarkable results with their anagen rate."
"The amount of cysteine in a hair fibre is an indicator of the hairs health. (J Cell Biol. 1990) In various animals, cysteine, along with other amino-acids and proteins, can protect hair and feathers and help them establish mechanical resilience. (Strasser et al., 2015)"
"Another study suggests that l-cysteine prevents the reduction in keratin synthesis induced by iron deficiency in human keratinocytes. It seems that l-cysteine promotes an important up regulation of keratins expression in the de novo protein synthesis and it counteracts the adverse effect of iron deficiency in keratin expression. (Miniaci et al., 2016)"
"The groups of mice received three dose levels of l-cysteine and vitamin B6 daily. Vitamin B6 was used due to its important role in incorporating l-cysteine in hair cells. After 6 months of exposure, the results showed that mice receiving the most l-cysteine/vitamin B6 doses had less hair loss, concluding that oral administration of vitamin B6 and l-cysteine may be an effective preventive treatment in alopecia. (D’Agostini et al., 2007)"
