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.

20 citations,
October 2017 in “Stem Cell Reports” The study demonstrated that Alkaline Ceramidase 1 (ACER1) was crucial for maintaining the homeostasis of hair follicle stem cells (HFSCs) and preventing premature hair loss in mice by regulating ceramide metabolism. Mice lacking the Acer1 gene showed increased ceramide levels, leading to HFSC depletion, disrupted hair follicle cycling, and progressive hair loss. The absence of ACER1 resulted in morphological changes in hair follicles, lipid accumulation, and impaired hair structure and function. The research highlighted the importance of ACER1 in regulating ceramide metabolism and maintaining HFSC homeostasis, suggesting its potential as a target for treating hair loss conditions.
