February 2026 in “European Journal of Pharmacology” In this study, teicoplanin significantly improved hair regrowth and follicle size in mice with dihydrotestosterone-induced androgenetic alopecia, suggesting its potential as a treatment option for hair loss due to its ability to enhance cell proliferation and decrease androgen receptor protein levels.
January 2006 in “Chinese Journal of Dermatology” This study found that cultured dermal papilla cells can induce hair follicle regeneration and sustain hair growth both in vivo and in vitro, with their effectiveness linked to specific protein expression levels.
4 citations
,
January 2019 in “Annals of Dermatology” In this study, researchers observed that RE-ORGA, a preparation from Korean herbs, may help alleviate androgenic alopecia by promoting human dermal papilla cell proliferation, reducing 5α-reductase enzyme levels, and displaying anti-inflammatory properties, suggesting potential regulation of androgen receptor sensitivity.
January 2015 in “Spectrum Research Repository (Concordia University)” This study confirmed that porcine platelet-rich plasma could commercially replace fetal bovine serum due to its higher growth factor levels and effectiveness as a hair growth promoter comparable to existing serum.
June 2020 in “Journal of Investigative Dermatology” This study found that spatial transcriptomics can reveal hidden inflammation patterns in atopic dermatitis by correlating epidermal and dermal gene expression levels, improving understanding of skin pathology.

,
October 2015 in “Experimental dermatology” This study found that adenine supplementation in cultured human follicle dermal papilla cells stimulated proliferation and reduced senescence, possibly through AMPK activation and increased cellular NAD+ levels.
April 2021 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that a shampoo containing a 6-active ingredient complex increased β-Catenin production in human hair follicle dermal papilla cells to levels comparable to Finasteride, suggesting potential for promoting hair growth. It also showed good cleaning efficacy, volume, and shine in a sensorial study.
February 2017 in “Spectrum Research Repository (Concordia University)” This study confirmed porcine PRP's commercial viability as a fetal bovine serum replacement, showing higher growth factor levels and stability, without increasing human follicle dermal papilla cell proliferation compared to FBS.
