This review discusses the effects of estrogen on skin aging and highlights potential therapies, but reports no new clinical findings.

This study found that minoxidil stimulates hair follicle growth by promoting dermal papilla cell survival and activating ERK and Akt pathways, which leads to increased proliferation and reduced cell death.

In this study, miR-31 was found to play a significant role in hair cycle regulation in mice by controlling key gene expressions involved in hair growth and differentiation.

Alopecia areata is an autoimmune disorder causing hair loss, linked to specific hair follicle antigens and genetic factors.

Some drugs can cause hair loss or increase hair growth, but these effects are usually reversible when the drug is stopped.

This review explores the complex endocrine functions of human skin and its role as a peripheral endocrine organ, but reports no new clinical results.

This study found that the effects of the vitamin D receptor on hair follicle cycling in mice are independent of its ability to bind a hormone, with specific domain mutations influencing hair regrowth outcomes.

This article reviews the concept of telogen effluvium and emphasizes the importance of identifying triggers and using diagnostic investigations to determine the cause of hair loss, without reporting new results.

This workshop overview concluded that follicular epithelial stem cells are multipotent and located in the bulge region of hair follicles, contributing to hair, epidermis, and sebaceous gland formation.

Apoptosis in hair follicles varies by growth phase, with TGF-β possibly starting the catagen phase.

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 found that alopecia in VDR-null mice persists despite undetectable vitamin D levels, indicating a defect in epithelial-mesenchymal communication due to the absence of ligand-independent receptor function.

This study identified mutations in the FGF5 gene as a cause of extreme eyelash growth in Pakistani families, highlighting a potential target for regulating eyelash growth.

This study found that subcutaneous administration of conditioned medium from adipose-derived stem cells promoted hair growth in mice, and hypoxia enhanced this effect by altering growth factor secretion.

This study found that low fluence photoepilation with intense pulsed light targets the pigmented area of hair follicles, causing temporary hair loss by inducing a catagen-like state without severe follicle damage.

This study demonstrated that HOXC13 directly influences hair keratin gene expression by binding to specific DNA motifs, suggesting its role in early hair follicle differentiation.

This report concludes that the blend method is the most effective electrolysis technique for permanent hair removal, requiring proper technique and preparation such as shaving before treatment to increase efficacy.

This study found that modulating BMP activity in transgenic mice affects the development and characteristics of several ectodermal organs, such as skin, hair, and claws, highlighting a stage-dependent influence on organogenesis.

This review provides a comprehensive guide to serum-free human hair follicle organ culture methods, highlighting research opportunities, standardization efforts, and potential applications without reporting new empirical findings.

In this study, different types of catagen in the C57BL/6 mouse model exhibited varying effects on hair follicle melanocytes and melanin distribution, with spontaneous and dexamethasone-induced catagen showing pigment incontinence, while cyclophosphamide-induced catagen retained dendritic melanocytes but increased ectopic melanin.

This study identified potential ceRNA regulatory networks in cashmere goat hair follicle cycling, expanding understanding of lncRNA and miRNA biology and annotation of the goat genome.

This study found that adult mouse dermis can be reprogrammed by epidermal cues to resemble neonatal dermis, with changes in fibroblast proliferation and extracellular matrix composition.

This study found that the petroleum ether extract from the leaves of Hibiscus rosa-sinensis demonstrated more effectiveness in promoting hair growth in rats compared to the extract from its flowers.

This study found that feeding aged mice a probiotic yogurt induced changes leading to thicker, healthier fur, suggesting a bacteria-triggered interleukin-10-dependent mechanism that mimics signs of youth and reproductive fitness.

This study found that applying dexamethasone to mice induced catagen-like follicle changes significantly earlier and more consistently than a vehicle, such changes being useful for studying hair follicle regression.

This study found that the methanol extract of Eclipta alba showed dose-dependent hair growth promoting activity in pigmented C57/BL6 mice by influencing the transition from the telogen to anagen phase.

This study suggests that miniaturization in pattern hair loss may occur abruptly and can be reversed with treatment, as supported by histologic evidence in finasteride-responsive patients.

This study found that restoring vitamin D receptor expression specifically in the keratinocytes of VDR null mice prevented alopecia and enhanced hair follicle response during anagen initiation.

This article reviews the clinical, psychological, and management aspects of androgenetic alopecia in men, stating that it can be effectively managed by generalist clinicians with pharmacotherapy and surgical advancements.

This study found that substance P and calcitonin-gene-related peptide have different roles in regulating hair growth in mice, with substance P promoting anagen progression and calcitonin-gene-related peptide inhibiting it.
