This study successfully grew and maintained human hair follicles in vitro, noting that TGF-β1 negatively affects growth, while EGF replicates hair-removal effects seen in animals.

In this study, insulin-like growth factor-1 did not impact hair follicle elongation in rat pelage hair follicles, while transforming growth factor-beta 1 inhibited both elongation and thymidine uptake.

In this study, Geranium sibiricum L. extract promoted hair growth in vitro with human dermal papilla cells and in vivo in mice, outperforming minoxidil by proliferating cells and stimulating growth factor expression, suggesting its potential as a hair growth treatment.

This review evaluates dihydrotestosterone's role in androgenic alopecia and proposes a model suggesting that chronic scalp tension and inflammation contribute to hair follicle miniaturization, identifying fibrosis, calcification, and tension as treatment targets.

In this study, the herbal complex of Houttuynia cordata, Perilla frutescens var. acuta, and green tea promoted hair growth in C57BL/6 mice, enhancing regrowth and follicle development compared to controls.

This study observed that human anagen hair follicles can grow in vitro when maintained serum-free, with possible implications for understanding hair follicle growth mechanisms.

This study found that MBN, an herbal extract fermented by Lactobacillus plantarum, promoted hair growth and increased related gene expression in C57BL/6 mice.

This study investigated the effects of the 60% alcohol extract from Alnus sibirica and its active compound, oregonin, on hair health, observing anti-oxidative and anti-apoptotic benefits in human hair dermal papilla cells exposed to oxidative stress, suggesting potential as natural materials for hair loss prevention.

This study found that Nelumbinis Semen extract may promote hair growth and reduce hair loss by increasing VEGF and IGF-1 expression and decreasing TGF-β1 in human dermal papilla cells and mice.

This study found that c-Maf positive M2 macrophages may promote hypertrophic scar formation by enhancing the proliferation, migration, and extracellular matrix deposition of hypertrophic scar fibroblasts through increased TGF-β1 expression.

This study developed a composite hydrogel that delivered multiple proteins, enhancing skin wound healing by accelerating closure and promoting hair follicle regeneration.

This preliminary study found that Melandrium firmum extract may promote hair growth and inhibit 5α-reductase, suggesting potential as a candidate for treating androgenetic alopecia.

In this study using lab models, YangHyulEum Gami-Bang (YHEG) was associated with promoting hair growth and inhibiting factors that contribute to hair loss.

This study indicates that Samhwang-Sasimtang ethanol extract may promote hair growth in a mouse model, showing stronger effects than a control but less than 3% minoxidil.

Yonnyuniksoogobon-dan taken orally promotes hair growth by affecting growth factors in hair roots.

This study found that Punica granatum ethanolic leaf extract may alleviate skin fibrosis in rats by modulating inflammation-related pathways and reducing dermal alterations.

This review examined and discussed the role of dermis-derived factors in the regulation of melanogenesis, noting their significance in both normal and abnormal mammalian skin conditions, suggesting an underexplored area of study compared to dermal and epidermal influences.

In this study conducted on rabbits, conventional blood treated with 120% sodium citrate was observed to achieve the highest platelet recovery and enrichment coefficient, while altering sodium citrate concentrate affected levels of growth factors PDGF and TGF-β1 after plasma activation.

In this study, the alcoholic extract DN106212 from Centipeda minima was shown to be more effective in promoting hair growth in C57BL/6 mice compared to dimethyl sulfoxide and tofacitinib, suggesting its potential as a natural hair growth agent.

This study suggests that oleanolic acid may promote hair growth in mice with testosterone-induced androgenetic alopecia by activating the Wnt/β-catenin pathway and influencing various molecular levels.

This study reports that taxifolin from enzymatic hydrolysis effectively regulates dermal papilla cell apoptosis and promotes hair growth by increasing IGF-1 and reducing TGF-β1, though it shows less inhibition of DHT compared to minoxidil.

This study found that VEGF growth factor plays a significant role in the development of androgenetic alopecia and telogen hair loss in women, more so than KGF, TGF-01, or EGF.

This study found that Chrysanthemum zawadskii extract may promote hair growth by inducing an earlier conversion of telogen to anagen and increasing the proliferation of dermal papilla cells in mice and human hair follicle cultures.

Certain hairstyles can cause scalp diseases, smoking is linked to hair loss, 5% minoxidil foam is effective for hair loss treatment, and various factors influence wound healing and hair growth.

This study found that in mice, the combination of azelaic acid and vitamin B6 enhanced hair regrowth, follicle elongation, and thickness more than individual treatments.

This study found that collagen peptides from Mozambique tilapia significantly promoted hair regrowth and increased the proliferation of hair growth factors in vitro and in vivo, suggesting potential as supplements for hair loss prevention.

This study found that molecular differences in paracrine factors between balding and non-balding hair follicles may enhance understanding of androgen action in hair disorders and potentially inform better treatments.

This review discusses the roles of various growth factors and cytokines in skin regeneration, highlighting their potential for future therapeutic development, and reports no new experimental findings.

In this study, rice bran supercritical CO2 extract demonstrated potential to promote hair growth in mice, increasing hair follicles and growth factor expression, similarly to 3% minoxidil.

This study identified a target relationship between miR-148a, miR-10a, and BMP7, suggesting these microRNAs influence dermal papilla cell proliferation and may regulate hair follicle growth.
