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 review discusses the role of exosomes in medical aesthetics, focusing on their mechanisms, production, and preservation, but reports no new clinical results and highlights barriers to their widespread application.

This study demonstrated that electrical stimulation via a polypyrrole-modified electrode enhanced trichogenic gene expression in human dermal papilla cells, leading to increased hair growth in a mouse model.

This study found that CuO/SiO2 nanowires enhanced with photothermal therapy exhibit significant antibacterial effects against E. coli and S. aureus and promote wound healing and vascularization, suggesting potential as an alternative treatment for infected wounds in mouse models.

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 chapter discusses the composition, biocompatibility, and production methods of biomaterials like collagen, chitin, and silk for dermal substitutes, focusing on preclinical and clinical research, but reports no new clinical results.

This review discusses strategies to regenerate human hair follicles using stem cells and reports no new experimental results; the authors note existing challenges and the potential of hiPSCs for future applications.

This review discusses the role of immune cells in mammalian hair cycle control and highlights their potential relevance to human hair cycling disorders, reporting no new clinical findings.

This study found that photoacoustic imaging can effectively measure follicle density and angles, even when follicles are not visible to the eye, providing a promising alternative to traditional photographic examination.

This study reports that using nanogel and layer-by-layer self-assembly to encapsulate single dermal papilla cells can form cell spheroids that regenerate hair follicles successfully in a hair follicle regeneration model.

This study found that Wnt10b promotes melanocyte maturation and pigmentation in the hair bulbs of mice by activating canonical Wnt signaling.

In this study, iNKT10 cells were found to play a significant role in preventing and treating alopecia areata in a humanized mouse model, suggesting these cells could have potential in managing related autoimmune disorders.

Non-thermal plasma helps hair grow by improving the area around hair follicles.

This study found that mutations in the hairless gene disrupt normal hair follicle development by impairing Wnt/β-catenin signaling, affecting hair keratinocyte differentiation in both mice and humans.

This study found that in transgenic mice overexpressing a mutant hairless gene, changes in its expression affected hair loss and regrowth, implicating the gene's role in hair follicle biology.

In this study of patients with Androgenic Alopecia, micro-grafts containing HD-AFSCs resulted in significantly improved hair density and follicle count over 11 months compared to a saline solution, suggesting a potential alternative therapy for hair regrowth.

The study suggests that a 3D culture system using the RAD16-I peptide scaffold can help restore the original phenotype of hair follicle dermal papilla cells and support their osteogenic and adipogenic differentiation.

This study found that poly(ethylene-co-vinyl alcohol) membranes support the self-assembly of dermal papilla cells into compact spheroidal microtissues capable of inducing new hair follicles, suggesting potential for large-scale production for hair follicle regeneration.

This study found that a 3D Matrigel culture technique for dermal papilla cell spheroids can enhance hair follicle inductivity and induce hair-like fiber differentiation in vitro, even with high-passage cells.

This study achieved a first by successfully forming large quantities of dermal papilla spheroidal microtissues, which retained their hair induction potential, using a micropatterned culture system.

This study observed that applying JAK-STAT pathway inhibitors to mouse and human skin led to rapid hair growth by inducing the anagen phase of hair follicles.

This study found that 'smart' peptide hydrogels improved wound healing in a rat model of partial thickness burns, achieving greater wound closure and faster debridement compared to a standard treatment.

This study found that human hair follicle-derived mesenchymal stem cells can differentiate into myogenic, osteogenic, adipogenic, and chondrogenic lineages, although this potential decreases over time and varies by lineage.

In this study using a mouse model, the researchers found that platelet-rich plasma significantly increased the number of newly formed hair follicles and decreased the time for hair formation compared to no treatment.

This study explored the complex roles of niche cells in regulating hair follicle stem cells, identifying specific cell functions such as signaling, sensing, and relaying messages, which could provide insights into treating hair loss conditions like androgenetic alopecia and alopecia areata.

In this study, nanocapsule-based preparations containing hinokitiol promoted hair growth in mice comparably to Minoxidil solution, as indicated by photographic and histological analysis.

This study demonstrated that a 3D air–liquid culture system using Wnt-CM-treated cells can induce hair regeneration in nude mice and may facilitate large-scale preparation for hair loss treatment.

This study developed a new protocol to efficiently produce skin dermal stem cells from human induced pluripotent stem cells, which may aid in treating various skin disorders.

The study suggests that abnormal activation of hair follicle stem cells and Wnt10b/β-catenin signaling may contribute to the development of sebaceous neoplasms.

In this study, overexpression of Wnt5a in mice was associated with the elongation of the telogen stage and inhibition of hair growth initiation, suggesting Wnt5a's role in maintaining hair follicle quiescence.
