This study found that 18-β-Glycyrrhetinic acid, a licorice component, stimulated human hair follicle cell proliferation, inhibited testosterone 5α-reductase, and suppressed TGF-β1, suggesting potential for treating androgenetic alopecia by promoting hair growth and prolonging the anagen phase.

This study investigated the effects of a YH complex, derived from Cinnamomum cassia and Astragalus membranaceus, on androgenetic alopecia in mice, finding that it promoted hair regrowth and improved hair follicle health by modulating hair cycle regulation and reducing apoptosis signaling pathways.

This review discusses platelet-rich plasma as a treatment for androgenetic alopecia and explains its mechanisms, but presents no new clinical results.

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.

LED light helps human hair root cells grow and prevents them from dying by activating specific growth pathways.

This review discusses various hormonal and neuropeptide influences on hair growth and reports no new clinical results; it highlights complexity and suggests areas for future exploration.

This study concluded that S. hexaphylla extract may improve androgenetic alopecia by reducing 5α-reductase and androgen receptor levels, inhibiting apoptosis, and promoting keratinocyte proliferation in experimental models.

In this study, decellularized human amniotic membrane was found to promote wound healing and reduce scar formation in rats with full-thickness skin defects, compared to traditional clinical treatments.

This study describes previously unknown immune characteristics of the normal human nail, highlighting its similarities to the hair follicle immune system and suggesting an immune privilege in the proximal nail matrix that both provides autoimmunity protection and presents infection susceptibility.

This study found that transcriptome profiling of cashmere goat skin revealed key genes and pathways involved in hair follicle initiation, differentiation, and maturation, which are critical for improving fleece production.

This study found that dermal papilla and dermal sheath cells from human scalp tissue differ from interstitial dermal fibroblasts in morphology and produce varying levels of TGF-beta 2.

This study developed a validated murine model of hypertrophic scar contraction, demonstrating similarities to human skin and observing graft contraction and tissue characteristics over time.

In this study using rabbits, HA2 hydrogels made from cross-linked hyaluronic acid and polysaccharide promoted wound healing better than other treatments, reducing inflammation and scar formation.

In this animal study, ginsenoside Rb1 demonstrated therapeutic effects on hypertrophic scar remodeling, with the highest efficacy observed at a dose of 0.56 mg.

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.

This study found that 4-aminopyridine significantly improved skin wound healing by enhancing wound closure, tissue regeneration, and cellular interactions involved in repair processes.

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.
