This article discusses various dermatologic surgical methods for managing skin conditions but reports no clinical results; the authors note that some manifestations of senile skin are not amenable to these procedures.

This study used air wedge interferometry to measure the thickness of human scalp hair from three individuals, finding average thicknesses of 66.482 µm, 59.355 µm, and 59.927 µm respectively, within the typical range for adults.

This study found that Caucasian hair is destroyed more easily than Asian hair when stretched, as indicated by changes in secondary structure, disulfide bond breakage, and physical disintegration.

This study introduced a new adaptive microrhizotron for non-destructive observation of pepper root traits, finding that specific installation patterns significantly enhanced root interception probability while effectively measuring root architecture for plant research.

This study found that oral spironolactone is generally well tolerated and may be effective for treating female-pattern hair loss, with improvements in hair regrowth stability as measured by Sinclair scores.

Hair loss negatively impacts quality of life, and psychological support can help.

This review found that many low-level light therapy studies report beneficial effects but often fail to provide adequate measurement details, affecting the reliability and repeatability of the research.

This review traces the historical understanding and treatment of acne across ancient Egyptian, Greek, and Roman civilizations, but provides no new clinical findings.

This study reviews the mechanisms by which SARS-CoV-2 may impact male fertility, noting potential disruptions in spermatogenesis and hormone secretion, and underscores the need for follow-up in recovered men.

This study developed a new measurement procedure using isotope dilution-liquid chromatography-tandem mass spectrometry for accurate quantification of DHEAS in human serum or plasma, demonstrating high selectivity, sensitivity, and low measurement uncertainty, making it suitable for routine standardization and clinical evaluation.

This study demonstrated that disrupting EGFR signaling in mice leads to immune sensitivity compromising the hair follicle's protective environment, but JAK1/2 inhibition can restore this immune privilege and stimulate hair growth, suggesting a potential therapy for scarring hair loss diseases like cicatricial alopecia.

This study found that anagen-phase hair follicles in mice are particularly sensitive to damage by ruby laser pulses, resulting in alopecia without scarring, suggesting enhanced laser hair removal strategies.

This paper reviews various techniques for measuring the physical and mechanical properties of human hair fibers, emphasizing their importance in developing effective cosmetic products.

In this study, researchers developed a method called the Stiffness-Angle Law and found that hair treated with caffeine-infused shampoo showed a 13.2% increase in stiffness, as measured by their novel evaluation technique.

This study demonstrated that RNA-seq can effectively expand hair follicle transcriptomic profiling in a multi-center study, offering deeper insights than blood transcriptomics alone.

This review discusses the impact of various exogenous agents on hair, such as cosmetics and radiation, but reports no new experimental results.

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

This study found that in rodent diabetes models, measuring corticosterone levels in new growth hair was more sensitive to hyperglycemia-induced changes than using old hair or serum samples.

This review discusses the regulation of hair growth, causes of excessive androgen secretion, and current safe solutions for hyperandrogenism manifestations in women but reports no new clinical results.

In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

This review discusses recent findings on how root hairs and root exudate secretion play critical roles in recruiting nitrogen-fixing bacteria, potentially aiding the development of cereal crops that can use atmospheric nitrogen, which may reduce reliance on synthetic fertilizers.

This article reviews complications associated with modern hair transplant surgery and discusses their treatment and prevention but reports no new clinical results.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

This study suggests that SOCS3 treatment may effectively inhibit alopecia areata by suppressing CD8+ T cell activity and IFN-γ production.

This commentary discusses the mechanisms of progression and potential regrowth in androgenetic alopecia, indicating that the initiation of anagen in kenogen follicles is more critical for hair density improvement than reversing follicle miniaturization.

This study concluded that rapid thawing during cryoablation enhances neutrophil and lymphocyte infiltration, increases oxidative stress, and induces cell death, resulting in more substantial tissue damage in mice compared to natural thawing.

Some chemicals can permanently or temporarily remove color from skin and hair, which can be distressing and is not well-regulated in cosmetics.

This review discusses recent advances in understanding the cellular, molecular, and genetic factors contributing to lupus erythematosus and reports no new experimental findings.

This review discusses primary cicatricial alopecias, detailing their classification, pathogenesis, clinical features, histopathologic findings, and treatment, without reporting new experimental results.

This review examines mesotherapy for local fat reduction, detailing its mechanisms, safety concerns, and the need for research toward FDA-approved uses, but reports no new clinical findings.
