This study found that chitosan and surface-deacetylated chitin nanofibrils promoted hair growth in mice and increased fibroblast growth factor-7 production in human follicle dermal papilla cells.

This article reviews the cellular dynamics affecting dermal papilla size in androgenetic alopecia and suggests targeting DP size could improve therapies, but it presents no new clinical data.

This review explores the regenerative potential of hair follicles and their role in complete skin regeneration, emphasizing the influence of mechanical factors and niche signaling pathways on hair growth and loss.

This review examines treatments for chemotherapy-induced alopecia, reporting that combining mechanical and chemical interventions may offer some benefits, though the evidence is not yet definitive.

This study found that melatonin treatment increased epidermal thickness, subcutaneous fat, and dermal-related factors in postmenopausal rats, suggesting benefits for skin structure after menopause.

In this study, the researchers found that combining physical dermabrasion with chemical peeling increased growth factors and neuropeptides more than chemical peeling alone in porcine skin samples.

This study found that the FGF-2 mimetic SUN11602 and VEGF mimetic ONO-1301 had unique effects on skin fibroblasts and keratinocytes, indicating potential for improving wound healing.

This study reports that γ-ray exposure in rats led to dermal endothelial proliferation, new vessel formation around hair follicles, and increased inflammatory markers, suggesting possible early stimulatory effects on hair growth.

This study found that applying a formulation derived from Bacopa procumbens significantly promoted hair growth, pigmentation, and follicular cycle acceleration in mice compared to minoxidil, potentially offering a new therapeutic approach for hair health.

In this study, TrichotechTM, a phytocomplex derived from essential oils, enhanced fibroblast proliferation, increased FGF-7 and FGF-10 gene expression, and boosted collagen content in cultured human fibroblasts.

This review explores the molecular controls of hair follicle cycling and highlights the challenge of developing effective treatments for common hair disorders without providing new clinical results.

This study demonstrated that engineered exosomes carrying EGF and FGF restored hair density and follicle integrity in an androgenetic alopecia mouse model by reactivating hair follicle growth factors, offering a novel therapeutic approach without immunogenic reactions or systemic toxicity.

This study found that Rubus coreanum extract promotes hair growth in mice, but its effects are not due to inhibition of specific enzymatic activities or growth factor expression.

This forum article in BMC Biology discusses evolving views on the concept of the stem cell niche, highlighting varied mechanisms and the need for better understanding of the niche's roles and functions.

In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.

This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.

This review discusses recent advances in how proinflammatory cytokines affect epidermal stem cell function during skin wound healing and introduces potential therapies targeting these cells and cytokines.

This study observed that autologous PRP and PDRN injections improved hair thickness and density in women with pattern hair loss, with combined therapy showing greater improvement in thickness than PDRN alone.

This study found that mice lacking the Vitamin D receptor showed disrupted hair follicle cycling, which was partially restored with hedgehog signaling pathway activation, suggesting a role for this pathway in follicle regulation independent of vitamin D.

This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.

This study found that over-expressing Spry4 and Fgf10 modulates feather stem cells to alter feather morphologies in distinct ways, affecting barb branch formation and tissue structure.

This study found that STAT5 activation in the dermal papilla acts as a key switch to trigger anagen entry in postdevelopmental hair follicle cycling.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

This study found that conditional knockout of N-WASP in keratinocytes of mice led to skin barrier defects, increased immune cell infiltration, and hyperproliferation of keratinocytes, indicating its crucial role in skin homeostasis.

This review examines the growing evidence for using platelet-rich plasma in aesthetic procedures such as hair restoration and skin rejuvenation but reports no new clinical results.

This study found that tannic acid accelerated wound healing in rats by modulating inflammatory cytokines, increasing growth factors, and activating the Erk 1/2 pathway.

This review highlights the critical role of TGF-β and FGF signaling pathways in the development and regeneration of skin layers, particularly the dermis, and discusses their significance in advancing future clinical applications in dermatology.

This study found that Tsukushi facilitates wound healing in mice by regulating macrophage function and myofibroblast differentiation.

This review discusses emerging targets for developing drugs to treat hair loss and reports no new clinical results; the authors emphasize the potential for therapies that regenerate hair follicles.

This study found that using layer-by-layer encapsulation techniques on dermal papilla cells can support their function and may help treat hair loss when used in conjunction with freshly isolated epidermal cells.
