This study found that, in Japanese patients with androgenic alopecia, sebaceous glands exhibit increased multilobulation which may be significant in the condition's pathology.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

In this study, human hair follicles showed varying expression of cholesterol transport proteins during the hair cycle, suggesting a potential role of cholesterol in hair growth and cycling.

This study found that Twist1 and Tcf4 synergistically regulate the hair follicle induction ability of dermal papilla cells by forming a complex with β-catenin, enhancing their biological properties.

This review discusses the emerging pathophysiological factors and potential new therapies for androgenetic alopecia beyond traditional treatments, but reports no new results.

In this study, miR-324-3p was found to promote differentiation and migration in cultured keratinocytes and is highlighted as a potential target for treating androgenic alopecia.

This review discusses the mechanisms underlying immune tolerance failure in alopecia areata and highlights potential therapeutic avenues for restoring hair growth and achieving sustained remission, but reports no new clinical results.

This review discusses the role of hair follicle bacterial colonization in immune responses and the pathogenesis of alopecia but reports no new clinical results.

This study suggests that decorin may help maintain hair follicle stem cells and its reduced expression could contribute to age-related hair loss.

This review discusses the current knowledge on using special and immunohistochemical stains for diagnosing hair disorders, concluding that no stains are recommended for routine use in hair pathology.

In this study, basal cell carcinoma developed in Ptch-deficient mice only after chemical treatment, not skin wounding, suggesting a second unknown event is necessary for tumor formation.

Various treatments exist for hair loss, but more research is needed for better options.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

Both methods improve hair density and thickness; double-spin may be more effective.

This study found that epidermal stem cell-specific Jag1 expression levels are crucial for effective wound healing and scar reduction, and porcine acellular dermal matrix treatment enhances this process in mice by boosting Notch/Jagged1 signaling.

This review emphasizes the potential of repurposing topical L-thyroxine for skin ulcers and telogen effluvium and highlights the need for further exploration of its use in dermatology.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

The study found that balding scalps have more thin hairs and larger oil glands, which might contribute to skin conditions related to hair loss.

This review examines the challenges of hair follicle regeneration and outlines strategies for bioengineering human hair follicle models, without presenting new experimental results.

This study found that the retinoid receptor and PPAR pathway are involved in hair follicle miniaturization in androgenetic alopecia, alongside androgen receptors.

In this study, researchers found that androgenetic alopecia is associated with increased gene expression related to inflammation, stress, and fibrosis, particularly affecting the hair follicle stem cells and showing similarities to diseases like psoriasis.

This paper proposes that the induction of HF-specific neo-antigens by peripheral CD8+ T cells may maintain self-tolerance but could also lead to immunopathology in conditions like alopecia areata.

This study found that CD99 is strongly expressed in the basal cells and hair follicles of normal adult and developing fetal skin, with expression patterns becoming similar after 20 weeks of gestation.

This review discusses the development of surgical hair restoration techniques and highlights the potential of hair follicle cell cloning to address current limitations.

This review explores the molecular processes behind hair follicle stem cell activation and suggests new potential targets for designing therapies for various types of alopecia, but it reports no clinical results.

This review explores the potential use of plucked hair follicles in regenerative medicine and diagnostics but presents no new research findings.

This commentary reviews potential dietary and mineral influences on androgenetic alopecia and suggests considering a diet low in cholesterol and glycaemic index with improved glucose control and magnesium fortification, without new clinical results.

This study explored the immune environment of the hair follicle's bulge region and suggested that its unique signaling may prevent melanoma formation by lacking necessary proinflammatory signals for full oncogenic transformation, indicating potential strategies for melanoma prevention by replicating this immune-privileged environment.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

This study found that mutant mice with the we/we wal/wal genotype exhibit significant defects in hair shaft structure and epidermis stratification, correlating with postnatal alopecia symptoms.
