May 2014 in “Pharmaceutical Biology” The study investigated the epilatory effects of glycyrrhizic acid, a compound from sweet licorice, on hair removal in Wistar rats. A solution containing 15% glycyrrhizic acid was applied to the rats' necks twice daily, resulting in 20-30% hair loss after 3 days and 90-95% after 6-12 days. Long-term treatment reduced hair regrowth by about 20%, with no signs of skin irritation. The study suggested that glycyrrhizic acid could be a potential treatment for hypertrichosis in humans, as it effectively removed hair without causing inflammation. Further research was needed to explore its effects on human hair growth and its potential mechanisms, possibly involving hormone-like effects or changes in hair cuticle structure.

January 1996 This study investigated the role of amino acids in human hair follicles, focusing on cysteine and arginine. It found that both amino acids were essential for hair growth and protein synthesis. Cysteine influenced hair fibre diameter, with reduced supply leading to thinning and growth retardation. Hair follicles utilized the amino acid transporter ASC for cysteine uptake, while arginine was primarily incorporated into proteins in the hair root sheaths and fibres. Arginine's availability affected energy metabolism, as indicated by changes in lactate production. The study also noted that certain peptide transporters were not expressed in hair follicles, and glutamate was transported more slowly than other amino acids.
