This study reports that Broussonetia papyrifera extract significantly increased hair count over 12 weeks in a small clinical trial and promoted dermal papilla cell proliferation in vitro by regulating WNT-β-catenin and STAT6 pathways.

This review discusses the composition, preparation, and applications of autologous platelet and extracellular vesicle-rich plasma, highlighting its potential benefits and the need for further research, but it reports no new clinical findings.

This review discusses the potential efficacy and applications of platelet-rich plasma in dermatology, highlighting its use in various skin conditions but reporting no new clinical results; the authors call for standardization of preparation and treatment methods.

This review reports that botulinum toxin is used in dermatology not only for treating rhytides but also for conditions like rosacea, hyperhidrosis, and menopause-related flushing, although its full safety and efficacy profile requires more research.

Genetic studies on hair traits can improve understanding of health and disease.

This study found that modern styling cosmetics can significantly alter hair structure through changes in interfacial chemistry and cohesion, particularly when applied to already damaged hair.

This preliminary study suggests that hyperbaric oxygen therapy may improve scalp health and follicle activation in healthy adults, with subjective assessments showing significant improvements despite mixed objective findings.

In this preliminary study, HBOT appeared to improve subjective measures of hair and scalp health in healthy adults, but objective changes in follicle density and hair properties were not statistically significant.

This study found that both red and green LED therapies combined with a microneedling patch significantly improved hair density and diameter in androgenetic alopecia patients over 24 weeks, with no serious side effects and similar efficacy between the two light wavelengths.

In this open-label study, the researchers observed that using Kerascalp hair serum daily for 90 days improved hair thickness, density, and strength while reducing hair loss in subjects with mild to moderate androgenetic alopecia, with benefits persisting even after discontinuation.

This narrative review reports that scalp micropigmentation offers immediate cosmetic improvements in hair density appearance, but does not promote actual hair regrowth and results vary based on the operator's skill.

This study found that platelet-rich plasma injections significantly increased hair count and density in patients with male pattern hair loss without major side effects, suggesting it may be a safe and effective treatment option.

This article reviews considerations and guidelines for testosterone therapy in older men with low testosterone levels but does not provide new clinical results, emphasizing the need for ongoing evaluation and careful management, particularly regarding risks related to prostate and cardiovascular health.

This study reported that Chinese women with PCOS exhibited diverse lipid profiles based on different characteristics, which may help understand their increased risk of cardiovascular disease.

This review discusses the diagnosis, management, and hormone treatment of transsexual individuals, and examines the risks and effects of cross-sex hormone therapy without presenting new clinical results.

This study found that platelet-rich plasma injections led to improvements in hair counts, thickness, and strength in patients with androgenic alopecia, showing promise as an effective treatment with no major adverse effects.

This review examines the potential of plant-derived exosome-like nanovesicles in dermatology, highlighting their bioactive properties and discussing challenges to their clinical application, but does not provide new clinical results.

This review examines the complexities of age-related skin healing and discusses how translating findings from model organisms to humans could enhance understanding and treatment of impaired regeneration in aging populations, but it reports no new clinical results.

This study found no significant benefit from PRP injections for treating androgenetic alopecia in men, highlighting the need for larger, well-designed trials to assess its effectiveness and safety.

This review examines melatonin's potential effects on human skin and hair follicle pigmentation, highlighting the need to confirm findings from cell cultures in physiological tissue contexts.

This study found that injectable platelet-rich fibrin (i-PRF) showed improved hair growth in males with Type VI and Type VII alopecia, which are typically difficult to treat.

This study found that preserving hair grafts in platelet-rich plasma before implantation significantly improved hair density, graft uptake, and hair thickness compared to saline preservation in hair transplantation patients.

This study generated a gene-edited cashmere goat with improved cashmere yield and fiber length by integrating VEGF at the FGF5 site, offering insights into hair growth mechanisms.

This study reports that a single transplantation of autologous stromal vascular fraction significantly increased hair density and keratin score in androgenic alopecia patients within six months.

In this study, black tea kombucha with and without MSM significantly improved hair density and length in mice, suggesting its potential as a natural hair regrowth treatment.

This study found that epithelial cells in the skin of live mice regulate the density and spatial organization of immune cells, which actively maintain their position despite constant cell turnover.

This review discusses the roles of distinct immune cell types in skin wound healing, highlighting findings from animal studies, but provides no new clinical results.

The researchers reported an optimized depilation procedure using cold wax and an extra skin protection step that minimizes injury in mice, revealing similar hair cycle kinetics across strains and supporting the use of Sv129 and B6129F1 mice in hair growth studies.

This study reports that adding androgen deprivation therapy to salvage radiation therapy for patients with non-metastatic biochemical recurrence of prostate cancer after radical prostatectomy improves progression-free survival, particularly in those with higher post-prostatectomy PSA levels.

This review examines experimental studies on the synergistic use of platelet-rich plasma and adipose-derived mesenchymal stem cells for wound healing in animal models, without reporting new clinical outcomes.
