This study observed that dissolving microneedles made from PVP-K90 and HPMC E50, incorporating Oryza sativa L. extract complex, showed enhanced transfollicular skin penetration and maintained safety for keratinocytes, with the P25H5 formulation demonstrating faster dissolution and greater effectiveness.

This study reported that a new deep learning algorithm using Mask R-CNN improved hair follicle classification accuracy by 4 to 15%, suggesting potential clinical application for enhanced hair loss diagnosis.

This study found a significant negative correlation between serum SHBG levels and androgenetic alopecia severity in women, but not in men, while no significant correlation was observed for testosterone, estradiol, dehydroepiandrosterone sulfate, and vitamin D levels with hair loss severity across genders.

In this interventional study on female-pattern hair loss, researchers found that fractional CO2 laser therapy alone improved hair growth, as evidenced by increased hair count, thickness, density, and patient satisfaction compared to saline controls. However, the precise mechanisms behind these effects require further investigation.

In this exploratory randomized controlled trial, participants using a combination of Centella asiatica-derived extracellular vesicles with recombinant growth factors showed significant improvements in hair thickness, density, length, and reduced hair loss and scalp sebum content after 56 days, compared to placebo.

This study observed that six sessions of injections using a stabilized hyaluronic acid compound improved hair thickness, shine, density, and reduced hair loss in volunteers with moderate androgenetic alopecia, with excellent treatment tolerability and high satisfaction reported by 88.5% of participants.

This study found that bulge cells marked by CD200+ in human hair follicles show high colony-forming efficiency, suggesting successful enrichment of keratinocyte stem cells.

This study found that the orphan protein Plet-1 is expressed in specific keratinocytes of mouse hair follicles and may regulate keratinocyte interactions with inert tissues by affecting migration and adhesion.

This study found that trichoscopy can differentiate between dermatomyositis, systemic lupus erythematosus, and systemic sclerosis by identifying distinctive features and may help assess disease activity.

This study found that a new three-dimensional high-frequency ultrasound (3D-HFUS) can successfully visualize skin tumors and inflammatory hair diseases, offering promising noninvasive diagnostic and evaluation capabilities compared to traditional two-dimensional methods.

In this study, androgenetic alopecia patients exhibited more nailfold capillary abnormalities, suggesting a potential link between microcirculation issues and the condition.

This review compiles current evidence on the molecular mechanisms, etiologies, and targeted immunotherapies for alopecia areata and reports no new experimental results, emphasizing the need for further research to manage the disease.

This review discusses how alopecia impacts patients' quality of life and evaluates the use and limitations of HRQoL questionnaires without reporting new clinical results.

This study observed that videodermoscopic assessments of dermatomyositis patients revealed specific vascular and pigmentary features, suggesting it may be useful for preliminary diagnosis.

This study found that CD34- melanocyte stem cells regenerated pigmentation more efficiently, while CD34+ cells showed potential for neuron myelination, suggesting different therapeutic applications for each population.

A common mutation in the hHb6 gene is linked to monilethrix, but other factors may also play a role.

In this study, a genetic analysis identified a pathogenic variant in the ALOXE3 gene associated with non-bullous congenital ichthyosiform erythroderma, and the patient's response to antifungal treatment highlights the risk of cutaneous fungal infections.

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.

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 paper does not provide study results; it shares author affiliations and publication details without reporting any findings.

This study demonstrated that a single multimode fiber can be used for single-shot wide-field reflectance imaging, achieving high correlation with the ground truth and enabling real-time microendoscopy at up to 180 frames per second.

This commentary discusses the use of microscopes in hair restoration surgery but provides no specific results or new insights.

This study developed a double-wavelength laser scanning microphotometer to measure hair shaft and follicle absorbance, improving spatial resolution and reducing light scattering effects in vitro.

This study introduces a customizable 3D-printed microscope stage insert for inverted confocal microscopes, improving accessibility and usability of intravital microscopy for observing cell dynamics in live mice.

This chapter highlights various commercial and open-source light sheet microscopy systems, detailing their rapid evolution and integration of multimodal technologies, with a focus on the ZEISS Lightsheet Z.1 system's advanced design for direct imaging and specialized sample mounting.

In this study, the researchers found that a manual micrometer caliper is a reliable tool for planning hair transplant surgery and accurately measures the short axis of the hair shaft.

This article discusses a new device for visualizing and quantifying skin distribution of a radioactively labelled compound, but reports no new clinical results.

This study found that Caucasian female hair is denser than Asian female hair in the occipital region regardless of treatment but thinner in diameter in both the frontal and occipital regions.

This study found that using a dissecting microscope for follicular unit graft preparation in hair transplant surgeries increased hair yield by 17% compared to using magnifying loupes with transillumination.

This study found that using a microscope can effectively distinguish between human and animal hair based on microscopic characteristics, making it a critical tool in forensic investigations.
