This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

This study found that mice lacking the type 3 IP(3) receptor in their hair follicles experienced repetitive hair loss and regrowth, indicating disrupted hair-cycle regulation potentially linked to specific signaling pathways.

This article reviews the role of adult stem cells in tissue homeostasis and wound repair, focusing on their regulation within the murine hair follicle's specialized niche, but it presents no new findings.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study found that UVB radiation significantly alters miRNA expression and induces cytotoxicity and apoptosis in normal human dermal papilla cells.

The researchers reported that minor salivary gland stem cells exhibit stem cell characteristics and respond to tobacco-derived carcinogens, implicating the transforming growth factor beta pathway in their maintenance.

In this study, the authors used AI-driven methods to identify and prioritize promising therapeutic targets that may address both aging and Glioblastoma Multiforme, proposing CNGA3, GLUD1, and SIRT1 as novel candidates.

In this randomized double-blind study, 160 adults with alopecia areata showed significant improvements in hair loss severity after using a bioactive peptide cosmetic product that mimics platelet-rich plasma, while the placebo group showed no significant change, underlining the treatment's potential effectiveness.

The researchers found that HOXC13 regulates different keratin proteins in a mixed manner, with certain SNPs impeding this regulation, while also demonstrating negative-feedback by HOXC13 and positive regulation by LEF1 and melatonin on the HOXC13 promoter.

This study found that higher levels of the protein Flii were associated with enhanced hair follicle regeneration and longer hair fibers in a mouse model.

This review discusses the varied roles of Wnt7a in development, tissue homeostasis, and cancer, reporting no clinical results; the authors emphasize the need for further investigation on its roles in inflammation and fibrosis.

In a porcine model, this study observed that using an External Tissue Expansion Device increased epidermis thickness, cell proliferation, and vessel density at fat graft recipient sites.

This review summarizes recent progress in human hair follicle bulge cell research, particularly the characterization and isolation of these stem cells, but reports no new experimental results.

This study found that conditioned media from dental pulp stem cells stimulated significantly faster hair growth in mice, suggesting potential as a treatment for alopecia.

This study found that hair germ cells, derived from bulge stem cells, respond faster to dermal papilla signals and have limited proliferation compared to bulge cells during hair regeneration.

This study found that Centipeda minima extract promotes hair growth by activating Wnt/β-catenin, ERK, and JNK signaling pathways in human hair follicle dermal papilla cells.

This study suggests that the secretome from amniotic fluid-derived mesenchymal stem cells overexpressing Nanog could stimulate hair growth and increase follicle density, potentially aiding in alopecia treatment.

This laboratory study found that activated platelet‐rich plasma supernatant enhanced hair growth signaling pathways in cultured human dermal papilla cells, suggesting potential for treating androgenic alopecia.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

This study found that Secretory Phospholipase A2-IIA (sPLA2-IIA) promotes proliferation through JNK/c-Jun signaling, distinctively affecting normal stem cells and cancer cells, suggesting it as a potential target for cancer treatment.

This study found that in women with PCOS, suppressive therapy using spironolactone plus oral contraceptives improved hirsutism more effectively than either treatment alone, with initial scores predicting success.

In this study, topical application of Hominis Placenta significantly promoted hair regrowth and increased hair density in C57BL/6 mice, suggesting its potential as a treatment for alopecia.

This study demonstrated that troxerutin may protect human dermal papilla cells from H2O2-induced damage and suggests potential in treating alopecia by inhibiting ROS-mediated cellular damage.

This review discusses platelet-rich plasma and cell-based therapies for hair loss, noting promising results but emphasizing the need for standardization and robust trials to confirm their efficacy.

This study suggests that transfection with modified KGF-mRNA enhances keratinocyte reepithelialization in wound therapy by temporarily increasing growth factor expression without affecting nuclear DNA.

This study found that topical application of mitochondrial electron transport chain inhibitors stimulated hair follicle stem cell activation and hair regrowth in aged mice by promoting lactate production.
