September 2023 in “Stem Cells International” This study using human and animal models found that adipose-derived stem cell exosomes promoted hair growth and counteracted dihydrotestosterone's inhibitory effects, suggesting potential therapeutic applications for androgenetic alopecia.
March 2023 in “International Journal of Molecular Sciences” This study found that exosomes from adipose mesenchymal stromal cells, particularly those carrying miR-122-5p, may enhance hair follicle regeneration in androgenic alopecia by targeting the TGF-β/SMAD3 axis.

July 2020 in “Science Advances” Dermal exosomes with miR-218-5p boost hair growth by controlling β-catenin signaling.
113 citations
,
November 2017 in “Scientific Reports” This study found that treatment with mesenchymal stem cell extracellular vesicles enhanced hair growth in mice and stimulated dermal papilla cell activity and growth factor production in vitro.
36 citations
,
February 2016 in “British journal of pharmacology” This study found that SIRT1 negatively regulates fibroblast activation and excessive scar formation, suggesting it may be a promising drug target for treating hypertrophic scars.
242 citations
,
February 2016 in “Science” This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.
184 citations
,
November 2014 in “Developmental Cell” This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.
42 citations
,
June 2009 in “Journal of Cosmetic Dermatology” In this study, researchers observed that follicular microinflammation significantly contributes to the early stages of male androgenetic alopecia, potentially leading to perifollicular fibrosis and follicle destruction as the condition progresses.
375 citations
,
February 2006 in “Journal of Cell Science” This article reviews the stages and regulation of the hair cycle, highlighting molecular regulators involved, but it does not present new research findings.
33 citations
,
April 2005 in “British Journal of Dermatology” This study found that age and follicular miniaturization were extremely weak predictors of total hair count in women with hair loss.
152 citations
,
December 2003 in “Micron” This review discusses the development, regulation, and aging of the human hair follicle pigmentary system and suggests potential for reversing hair graying by manipulating follicle melanocytes in vitro, but reports no clinical results.
