This study describes a distinct pattern of trichoscopic features associated with chemotherapy-induced alopecia and how these features evolve through different phases of chemotherapy treatment.

This article discusses the potential genetic basis of central centrifugal cicatricial alopecia in women of African ancestry but does not provide new research results.

This study found that disrupting the Sox21 gene in mice led to progressive hair loss and regrowth, identifying Sox21 as a key regulator of hair shaft cuticle differentiation.

This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

This study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

In this study, cross-sex hormone therapy affected hair growth patterns differently, with estrogen reducing hair growth in male-to-female transsexuals and testosterone increasing it in female-to-male transsexuals; however, male typical hair diameters were not fully reached in the latter group after 12 months.

This study identified a cluster of genes on chromosome 17 related to hair keratin-associated proteins, including 37 genes forming seven multigene families, localized in the hair shaft's upper cortex.

This study observed that a wearable electric stimulation device significantly promoted hair regeneration in rats and mice, outperforming conventional pharmacological treatments and enhancing growth factor secretion.

This review discusses follicular transplantation for hair restoration, highlighting the importance of evaluating patient suitability and careful planning to achieve excellent cosmetic outcomes, but reports no new research findings.

This study identified five mutations in the gene LSS in individuals with unexplained hypotrichosis simplex, highlighting a potential role of mislocalized LSS proteins in disrupting hair follicle biology.

This study found that the S100A3 gene is exclusively expressed in hair follicle cells differentiating into hair shaft components in mice, suggesting its important role in hair formation.

This study found that hair shaft miniaturization in aging and genetic hypotrichosis leads to hair follicle stem cell loss through mechanical compression and apoptosis mediated by the Piezo1 channel.

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 research observed that translation initiation shifts from cap-dependent to IRES-mediated pathways varied across tissues and cell types under stress and differentiation conditions in mice, with low IRES/Cap ratios signaling high stemness and potential multipotency, mediated by the RNA processing protein PTBP1.

This article offers guidance for hair transplant surgeons on addressing old or poorly executed transplants, focusing on surgical precision and effective use of limited donor hair to enhance cosmetic outcomes.

This review summarizes fundamental concepts and recent advancements in hair follicle biology, including insights from mouse models into broader molecular and cellular processes relevant to regeneration and development.

This article provides an overview of how dermoscopy can aid in the noninvasive diagnosis of various general dermatological disorders, grouped by clinical presentation, but reports no new clinical results.

This article discusses the structure of hair follicles and their significance in evaluating hair disorders, but it does not report any new research findings.

This study identified novel compound heterozygous mutations in the DSG4 gene in a Japanese patient with congenital hypotrichosis, suggesting overlap between localized autosomal recessive hypotrichosis and monilethrix.

This study revealed that human keratin-associated protein genes are expressed in specific patterns in hair fiber regions and vary in size, with some variations distinct across different populations.

This review discusses recent advances in trichoscopy for differentiating types of alopecia and presents a systematic approach for using its diagnostic findings, but reports no new clinical results.

This review identifies genetic mutations associated with congenital hair loss disorders in Japanese populations, particularly highlighting common LIPH gene mutations linked to woolly hair/hypotrichosis, and reports no new clinical results.

In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

This review discusses diagnostic challenges and management approaches for pediatric hair disorders, emphasizing the importance of distinguishing between acquired and congenital conditions, and reports no clinical results.

This study observed that follicular dysplasia in Weimar Pointers produces histopathological features and hair abnormalities similar to color dilution alopecia, though less severe.

This study found that genetically variant peptides from human hair can reliably identify individuals despite differences in age and storage conditions, provided environmental and processing factors are controlled.

This case report highlights traction alopecia in two adolescent Sikh brothers who developed scarring alopecia from wearing a turban, emphasizing the importance of early changes in hair care to prevent irreversible hair loss.

This systematic review evaluated 60 studies on trichoscopy in hair and scalp disorders, revealing gaps in accounting for variables like disease stage or hair texture, and underscoring a need for more comprehensive analyses to fully understand trichoscopic patterns.

This article discusses the uses and techniques of trichoscopy for hair and scalp disorders and reports no new clinical results.
