In this split-scalp study, researchers observed that combining fractional CO2 laser and PRP treatment was significantly more effective in improving hair parameters in women with female pattern hair loss than using each intervention alone or placebo.

This study found that a food supplement improved skin moisturization, elasticity, and thickness, reduced telogen hair density, and enhanced nail status in women with mild-to-moderate aging signs after 84 days.

This study found that platelet-rich plasma is effective and safe for treating chronic wounds, particularly diabetic and venous ulcers, and vitiligo, without increasing the risk of infection.

This study found that a novel nutraceutical supplement improved hair growth and strength in subjects with hair thinning compared to placebo, without reported side effects.

This review compares mesotherapy and PRP for hair loss but reports no new clinical results; the authors highlight the need to understand their differences for optimal treatment choices.

This article previews a Journal of Investigative Dermatology quiz on diagnosing male androgenetic alopecia and offers no new research results.

This study found that pharmacopuncture and topical application of Sebalgukhwa-san extract improved hair growth, density, and thickness in an alopecia mouse model without affecting liver function.

This study found that iontophoresis with growth factor cocktail including fibroblast growth factor 5-short significantly increased hair density in patients with androgenetic alopecia over 24 weeks.

This study found that transgenic expression of COX-2 in mouse basal keratinocytes causes epidermal hyperplasia and certain dysplastic features at specific body sites.

In this study, ALRV5XR significantly increased hair regrowth in women with androgenetic alopecia or telogen effluvium, with no adverse events reported.

In this study, ALRV5XR treatment significantly increased terminal hair density in men with androgenetic alopecia after 24 weeks, while also decreasing vellus hair density, and was well tolerated without adverse events, suggesting its potential efficacy over standard therapies.

This review discusses the categorization of hair loss and increased hair density disorders related to systemic diseases and reports no clinical results, emphasizing the potential diagnostic value of history, physical examination, and histopathologic data.

This study found that the HairMax LaserComb® significantly increased hair density and was safe and well tolerated for treating androgenetic alopecia in men compared to a sham device.

This retrospective study found that treatment with autologous plasma rich in growth factors increased hair density and improved hair follicle health in patients with androgenetic alopecia, with no reported adverse effects.

This study found that females with androgenic alopecia experienced greater improvements in hair density after cosmetic treatments compared to males, in a cohort stratified by age and gender.

In this study, researchers developed a microfluidics-based method for creating uniform, size-controlled stem cell spheroids that enhance osteogenic differentiation when encapsulated in alginate-RGD microgels.

This study reported that a magneto-responsive transdermal microneedle system delivered Minoxidil effectively and significantly increased hair density by 800% in mice with androgenetic alopecia after 10 days.

This review concludes that platelet-rich plasma is a promising treatment for androgenetic alopecia, enhancing hair density and thickness, though outcomes vary due to differences in preparation and application methods.

This review discusses the features and diagnosis of metabolic syndrome in obese children and reports no new findings, highlighting the need for a uniform pediatric definition and early intervention.

This study found that 675 nm laser treatment improved androgenetic alopecia in Indian patients, resulting in significant increases in hair count, density, and thickness after 14 sessions, enhancing the anagen phase and other hair-related parameters.

In this case report, a 36-year-old male with androgenetic alopecia showed clinically visible improvement in hair density after three monthly sessions of microneedling combined with exosome application, although the authors note that further studies are needed to verify these findings.

This review found that hydrolyzed collagen supplementation, particularly marine collagen, improves skin hydration, elasticity, and density while strengthening hair and nails, especially when paired with vitamin C and trace elements; however, more studies are necessary to evaluate long-term efficacy across different sources and demographics.

In this study, researchers found that nanomaterials designed for plastic surgery applications show promising results, including a 95% dynamic wrinkle filling rate and enhanced hair density by 41%; however, challenges like potential long-term safety issues and high production costs must be addressed.

In this study, 14 sessions of 675 nm laser stimulation significantly improved hair count, density, and thickness in Indian patients with androgenetic alopecia, with an increase of around 17% in hair parameters over four months.

This study reports that a prototype device may accurately measure changes in hair quantity, diameter, and density in patients with balding by assessing the cross-sectional area of hair bundles.

This study observed that in chicken skin, large-scale differences in gene expression between feathered and scaly skin are controlled by enhancer-driven uniform expression, while small-scale differences within individual feathers are associated with chromatin looping.

Combining FUE hair transplantation with PRP improves hair density and patient satisfaction in scarring alopecia.

In this study, researchers found that epithelial cells exhibit density-dependent metabolic heterogeneity, particularly in the pre-epithelial transition stage, where metabolic patterns correlate with cell proliferation and are influenced by actomyosin contractility.

This study found that washing hair with surfactants reduces the internal density of hair due to cuticle lifting, and suggests that a cuticle-sealing strategy can inhibit this effect and maintain hair homeostasis.

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.
