January 2015 in “Seoul National University Open Repository (Seoul National University)” This study reports that polyunsaturated fatty acids, particularly arachidonic acid alone and combined with eicosapentaenoic acid, may stimulate hair growth and enhance hair growth factors in mice and human dermal cells.
January 2014 in “Sen i Gakkaishi” In this study, liposome-encapsulated thioglycolic acid improved hair perming by enhancing the penetration of perm solutions, resulting in a stronger S-shaped wave and higher cysteine content compared to the control.
August 2013 in “Fertility and Sterility” This study found that women with PCOS have higher follicular fluid levels of testosterone and IL-6, despite similar NEFA levels to non-PCOS women, suggesting increased lipotoxicity impact on androgenesis in PCOS.
This review explains that linoleic acid deficiency can lead to skin and growth issues but notes that such deficiencies are rare in well-nourished Western populations; it reports no new clinical findings.
September 2008 in “Fertility and Sterility” This study found that in female dogs, exposure to free fatty acids increased androgen production, suggesting a potential link to factors characteristic of polycystic ovary syndrome.
Procyanidins and phosphatidic acids help promote hair growth.
March 2005 in “Journal of the American Academy of Dermatology” This study found that reintroducing certain depleted amino acids into weathered hair using cosmetic treatments can strengthen the hair, improving its look and feel and reducing damage and breakage.
January 1992 in “Research Online (University of Wollongong)” This investigation reviews the potential impact of polyunsaturated fatty acids on thyroid hormone action and does not report new results, highlighting a need for further research on dietary treatment for hyperthyroidism.
January 2026 in “JPRAS Open” In this pilot study, PDLLA scalp microinjections showed improvement in physician-rated Global Aesthetic Improvement Scale scores over 12-24 weeks for 90% of patients with non-scarring alopecia, with no serious adverse events reported, although findings remain preliminary due to methodological limitations.
December 2022 in “Scientific Reports” This study found that caffeic acid amide derivative, compound 4, effectively inhibited steroid 5α-reductase type 1 in vitro, suggesting potential for development as a treatment for androgenic alopecia.
