This study found that psychoemotional stress disrupts hair growth in mice by terminating anagen and suggests a potential pathway for pharmacological management of stress-related hair loss in humans.

This study demonstrated that blocking the Sonic hedgehog signaling pathway in mice led to reversible inhibition of body coat hair morphogenesis, while whisker development was unaffected.

Fungi-produced compounds can change plant root growth.

This review examines hair cosmetics, including shampoos and conditioners, for their formulations and effects, but reports no new clinical findings; it emphasizes the importance of dermatologist knowledge in treating diverse hair conditions.

This study found that activating β-catenin signaling in embryonic epidermis promoted hair follicle characteristics at the expense of normal epidermal differentiation, leading to early pigmentation and innervation.

This study found that the GhDET2 gene plays a crucial role in cotton fiber initiation and elongation, suggesting that modifying brassinosteroid biosynthesis may enhance fiber quality or yield.

This study found that the prevalence of androgenetic alopecia increases with age among both men and women in Maryborough, Australia, with 57% of women and 73.5% of men aged 80 and over affected.

This study found significant species differences in the enzyme activity and inhibitor affinities of prostatic 5α-reductases from rats, dogs, and humans, with variable potencies for different 3-oxo-4-azasteroid inhibitors across species.

In a mouse model, this study demonstrated that a microneedle patch system using keratin and integrated with MSC-derived exosomes and UK5099 promoted hair regrowth more efficiently than traditional delivery methods.

This review discusses the advancements in biologic skin substitutes for wound treatment and their potential in enhancing cutaneous regeneration but reports no new clinical results.

The researchers reported that hair follicle development and commensal microbe colonization promote the accumulation of regulatory T cells in neonatal skin, with the Ccl20-Ccr6 pathway playing a key role in this process.

This review discusses skin-related toxicities associated with targeted cancer therapies and emphasizes the need for dermatologists to understand and manage these adverse effects, but reports no new experimental results.

This study suggests that metformin may be more effective than Dianette in treating moderate to severe hirsutism in women with PCOS, while also reducing markers of insulin resistance.

This article examines the terminal to vellus transition in androgenetic alopecia through cellular and developmental mechanisms, discussing challenges and knowledge gaps without presenting new clinical findings.

This study found that minoxidil significantly increases VEGF mRNA and protein expression in dermal papilla cells, suggesting a role in enhancing hair follicle vascularization in androgenetic alopecia.

Hair loss can cause low self-esteem, anxiety, and depression in men.

This study observed that androgen levels rise with pubic hair development in Tanner stages, differing by sex and age, with DHEA showing a significant prepubertal increase especially in precocious adrenarche.

This study reviewed recent theories on alopecia areata's pathogenesis, highlighting its autoimmune nature due to immune privilege disruption in hair follicles, and noted current treatments have limited efficacy with high relapse rates, underscoring the need for further research into its mechanisms for better therapies.

This study found that surgical deactivation of migraine trigger sites significantly reduced or eliminated migraine symptoms in most treated patients, compared to controls, and also decreased migraine-associated costs and workdays lost.

This review discusses the potential uses, benefits, and challenges of solid lipid nanoparticles in drug delivery systems but presents no new experimental findings.

This study found that polycomb-group-mediated repression plays a key role in regulating hair follicle stem cell states and lineage progression by distinct mechanisms in adult mouse skin.

This review discusses the acyl-CoA synthetase very-long-chain (ACSVL) enzyme family, including its biochemical characteristics, tissue expression, and involvement in lipid metabolism, but presents no new experimental results.

Male pattern baldness is largely genetic, linked to the androgen receptor gene, and may relate to certain health issues.

This review discusses herbal therapies for dermatologic disorders, focusing on those with scientific evidence of efficacy and common interactions, but reports no new clinical results.

This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.

This review discusses the role of the sonic hedgehog pathway in skin development and cancer, highlighting its potential as a target for chemoprevention and treatment; it reports no new findings.

In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.

This study reported that women with polycystic ovary syndrome had a higher prevalence of impaired glucose tolerance and type 2 diabetes, with variations influenced by ethnicity and obesity.

This study developed and validated a method for extracting cortisol from human and animal hair, suggesting its potential as a biomarker for assessing chronic stress exposure.
