In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

In this observational study, hair density was found to vary with age, as measured in subjects from a dermatology outpatient department, with males showing a mean unit density of 104.78 and females 108.36.

This study found that hair canal and follicle diameters, outer root sheath area, and terminal-to-vellus hair ratios were significantly reduced in androgenetic alopecia patients compared to normal controls.

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.

This study found that scalp thickness and hair follicle depth were reduced in individuals with androgenetic alopecia, and MRI signal intensity was higher compared to those without the condition.

This study found that chemotherapy in female breast cancer patients caused significant early hair loss, which began to recover three months after completion, whereas tamoxifen did not affect hair growth.

This study found that in the Thai population, hair density varies by scalp location and decreases with age, and that Asians generally have lower hair density compared to Caucasian and African populations.

This study reviews methods to ensure the reliability of machine learning models in medical imaging, focusing on bias detection, data drift assessment, and accuracy estimation without ground truth labels to enhance integration into clinical settings.

In this study, researchers found that chemotherapy-induced alopecia counseling and resource access are insufficient and influenced by socioeconomic factors such as employment, income, and education, underscoring the need for standardized education and improved resource availability to address disparities.

This study explored how an educational intervention on reducing phthalate exposure through hair care product choices influenced the hair care practices of pregnant women of color, identifying key life stages and themes related to these practices, including cultural influences, product impacts, and individual autonomy.

In this study, a computer-aided imaging system accurately measured the width of balding areas in female pattern hair loss, correlating strongly with clinical staging severity.

This study reports that the TrichoScan method effectively measures hair growth parameters and detected significant improvements in hair counts and thickness in men with androgenetic alopecia after finasteride treatment.

This study presents a new approach to automatically remove hair artifacts from dermoscopic images, which reportedly performed well compared to existing methods like DullRazor using the PH2 datasets.

This study developed and validated a comprehensive method using mass spectrometry to profile sex (pro)hormones in plasma, with results showing reliable calibration and detection of 31 analytes in samples from pre- and postmenopausal women and men, while addressing potential over- or underestimations in analyte concentrations.

This study found that NIH hairless mice exhibit abnormalities in hair growth and immune-related pathways, with Pik3r1 and Pik3r3 identified as key genes for further investigation.

This study established an animal model using UV-irradiated C57BL/6 mice to assess hair luster, reporting that UV exposure alters keratin-associated protein gene expression, and suggested potential for developing effective hair care products by evaluating treatments like oral minoxidil.

This study reports that women with hair loss had significantly lower levels of several biomarkers, including hemoglobin, iron, copper, selenium, vitamin D, vitamin B12, folate, and thyroid hormones, compared to healthy controls.

This study describes a new method using high-resolution mass spectrometry for analyzing multiple steroids in human scalp hair, with newborn hair showing the highest steroid concentrations among examined age groups.

This study found that injecting bone marrow-derived mesenchymal stem cells and conditioned medium into mice promoted hair follicle stem cell proliferation and transition to active growth phases, suggesting potential clinical targets for hair loss treatment.

This study found that the Antera 3D® system provided an objective and sensitive method for assessing pediatric pathological scars, capturing significant changes in pigmentation, vascularity, and volume, compared to the traditional Vancouver Scar Scale and dermoscopy, which showed varied sensitivities across different scar parameters.

This retrospective study found that serum hormone levels and MRI detection of ovarian nodules contributed to distinguishing virilizing ovarian tumors from ovarian stromal hyperthecosis in postmenopausal women, though histopathology remains crucial for diagnosis.

In this study, female pattern hair loss in Chinese Han patients was characterized by decreased hair density and shaft diameter, with minor gender differences and the vertex most affected.

This study highlights the distinct distribution patterns of extracellular matrix components in the scalp skin of male and female androgenetic alopecia patients, with increased elastin staining intensity observed in male cases.

This mini-review summarizes the Trichoscan as a sensitive tool for measuring hair growth parameters, demonstrating its effectiveness in detecting treatment response in androgenetic alopecia but noting some practical limitations.

This study identified three new genetic loci linked to sweat gland density in a GWAS involving 6,210 Han Chinese individuals, highlighting potential targets for understanding conditions like anhidrosis and hyperhidrosis and emphasizing the use of quantitative traits in genetic dermatology research.

This study found that the revised 43-item PCOSQ had better validity and reliability than the original version, although further studies are needed to assess its predictive efficacy.

This study reveals that somatosensory neurons in mouse skin exhibit structural plasticity during hair-follicle regeneration, which may temporarily impair the reliability of encoding gentle touch.

This article reviews trichoscopic techniques for diagnosing common hair loss conditions and presents a revised algorithm for identifying specific features of cicatricial and noncicatricial alopecia, but reports no new clinical results.

This study found that individuals with androgenetic alopecia experience significantly higher symptoms of anxiety, depression, and stress compared to controls, along with reduced self-esteem and life satisfaction, highlighting the importance of addressing psychological well-being in clinical treatments.
