This study used ultrahigh-resolution optical coherence tomography to observe hair shaft structures, finding melanin granules absent only in white hair, which may explain color differences between black and white hair.

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 used quantitative methods to identify new geometric and mechanical parameters of curly and kinky/coily hair, aiming to improve classification and develop better personal care products for these hair types.

This study found that standardized scalp massages may help stabilize or regrow hair in individuals with androgenic alopecia, as perceived by the participants themselves.

This correspondence reported significant variability between quantitative PCR and bDNA assays for measuring Hepatitis C virus RNA in high-titer specimens, challenging the reliability of the Chiron assay.

This study reports that the new neighborhood face index (NFI) demonstrates a remarkably high correlation with the physiochemical properties of benzenoid hydrocarbons, highlighting its potential as a predictive tool.

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 review found that 5α‐reductase inhibitors were associated with slightly increased rates of decreased libido, erectile and ejaculatory dysfunction, gynecomastia, and mood disorders compared to placebo, though their long-term effects remain unclear.

This study identified 374 eQTLs in scalp hair follicles associated with genes involved in metabolic, mitotic, immune processes, and responses to steroid hormones, contributing insights into genetic variation and hair traits.

This study developed and validated a reliable RP-HPLC method for accurately quantifying dutasteride in pharmaceutical formulations and bulk pharmaceuticals using a Shiseido C18 analytical column, demonstrating precision, accuracy, and sensitivity across a concentration range of 10 to 22 ppm.

This study reports that among men, skin surface hydration and pH change with age, but transepidermal water loss and sebum production show less variation.

This publication reviews the World Professional Association for Transgender Health's Standards of Care for supporting transgender and gender nonconforming people, with adjustments needed for diverse global contexts and no new clinical results.

This study observed that Japanese women experience diffuse central hair loss after age 40, characterized by reduced hair density and thicker hair ratio rather than vellus-like hairs.

This review outlines the current state of freeze-dried platelet-rich plasma (FD-PRP) research, emphasizing its use in wound healing, lumbar fusion, knee conditions, and dentistry, but reports no new clinical findings.

In this mouse study, hair growth defects associated with the Gk5 null allele were partially alleviated by simvastatin treatment, suggesting GK5 plays a key role in skin-specific cholesterol regulation.

This case report highlights the rare occurrence of overlapping syndromes including SLE, RA, and AAV in a patient with discoid lupus erythematosus, noting the persistent role of prior viral infection remains unclear.

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.

This study identified new geometric and mechanical parameters for curly and kinky/coily hair, which may inform more effective personal care products tailored to these hair types.

This study found that biostimulant application in lettuce cultivation led to significant yield and phytochemical enhancements, with effects varying between green and red cultivars depending on the treatment method used.

This practical guide introduces methods to study human dermal white adipose tissue but does not report new clinical results, emphasizing available techniques and staining protocols.

This narrative review found that while AI-based tools in dermatology, particularly for hair disorder assessment, have potential to enhance clinical practice by improving objectivity and personalization, they currently serve mainly a complementary role and face challenges like methodological limitations and data bias.

This study demonstrated that a new non-invasive method for collecting and analyzing mouse hair follicles could replace traditional biopsy methods, providing advantages for translational research and routine applications.

This study utilized a UHPLC-HRMS method to identify eight active pharmaceutical ingredients, such as ketoconazole and minoxidil, in 26 out of 100 analyzed cosmetic products.

High-quality photos help track hair growth progress in androgenetic alopecia patients.

This study found that melatonin receptor genes play a key regulatory role in the development of goose skin feather follicles during embryonic development.

This review explores the role of hyperandrogenism, including adrenal-derived 11-oxygenated androgen, in the development of polycystic ovarian syndrome and discusses potential therapeutic strategies targeting androgen excess, without reporting new clinical results.

This study investigated the formation of Type III brush hair in Chinese Haimen goats and identified genetic factors that may involve heat stress in the process.

This study found that applying BMP2 stimulated limited regeneration of the amputated P2 bone in mice, but only when applied during a specific "regeneration window" after injury.

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.

In this study, researchers found that the cashmere hair growth cycle is divided into three periods and key genes like KAP and KRTAP are positively correlated with these cycles in cashmere goats.
