This study found that 62% of neutered dogs with hair cycle arrest experienced partial to complete hair re-growth after melatonin treatment, but hair re-growth was not consistently linked to normal sex hormone levels.

This case study of a cat with pancreatic carcinoma and paraneoplastic alopecia found that removing the internal tumor reversed hair loss, but symptoms reappeared as the cancer metastasized.

This study found that surface modified nanoparticles showed increased skin permeation and improvement in allergic contact dermatitis, independent of the follicular pathway.

In this study, researchers differentiated induced pluripotent stem cells into cells with dermal papilla-like properties, demonstrating their potential role in hair follicle bioengineering and drug testing for hair growth.

This chapter reviews surface plasmon resonance (SPR) methodology and its applications in basic science and human disease without reporting new clinical results.

This study found that in androgenetic alopecia, reduced stem cell factor production by dermal papilla cells may lead to decreased pigmentation in hair follicles.

In this study, a novel electrochemical sensor using a molecularly imprinted polymer was developed for the sensitive detection of minoxidil, successfully measuring its concentration in real samples.

Injecting platelet-rich plasma (PRP) can increase hair growth rate and density in male pattern baldness.

This study demonstrated that keratin derived from human hair can improve axon extension and alleviate motor deficits from sciatic nerve injuries, highlighting its potential as a promising biomaterial for peripheral nerve regeneration.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

Hairless mice lack fur due to a genetic mutation affecting skin response, not hormone issues.

This study found that cyclosporine A treatment at 5 mg/kg/day may reduce inflammation and promote gland regeneration in dogs with sebaceous adenitis, though symptoms returned when treatment stopped.

This study found that in dogs with alopecia, certain steroid hormone levels were elevated, particularly progesterone, but not all hormone abnormalities were consistent across breeds, suggesting the need for breed-specific evaluation.

This study found that local refinement of hair follicles into higher order patterns can occur without the core planar cell polarity system, but global alignment with body axes requires its function throughout development and regeneration.

This study sequenced and analyzed the goat skin transcriptome, revealing genes involved in signal transduction and cell communication that are differentially expressed during hair growth phases, providing insights for Cashmere goat breeding.

This review discusses the historical development and current challenges in in vitro hair follicle culture, highlighting a need for advanced models using cell lines and tissue engineering, and reports no new results.

This study found that male liver cirrhosis patients have higher estradiol levels and lower dehydroepiandrosterone sulfate, leading to hormonal imbalances favoring estradiol, but without changing sex hormone-binding globulin's binding properties.

In this study, dogs with hair cycle disorders, especially those with alopecia X, showed a significant increase in the number of kenogen follicles, suggesting impaired induction of new hair growth phases.

In this study, researchers identified a novel congenital skin disorder in Chesapeake Bay retrievers, linked to a plakophilin-1 deficiency due to a genetic mutation, marking the first known occurrence in an animal species.

This study identified a large deletion in the desmoglein 4 gene as the genetic basis of the Iffa Credo "hairless" rat's skin phenotype, linking it to lanceolate hair mutations.

This article reviews studies on thyroid influence on hair growth, noting varied results, including accelerated growth in some normal and underfed rats after thyroid administration, but reports no clinical results.

Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This study found that a bacterial endophyte from Zea nicaraguensis effectively targets and colonizes plant root hair cells, promoting growth and solubilizing insoluble phosphorus for nutrient uptake.

This review discusses the hormonal influences on hair cycling disorders in post-partum and postmenopausal women and notes the lack of evidence for effective targeted treatments.

In this study, spironolactone was reported to stabilize or improve female pattern hair loss in 74.3% of treated women, especially those with signs of hyperandrogenism.

This study found that in mice lacking EGFR, elevated Wnt signaling disrupts hair follicle development by affecting cell proliferation and differentiation, revealing a critical role for EGFR in regulating these processes.

This study observed that NSPC predominantly differentiated into neurons when exposed to serum fractions with molecules under 100 kDa, particularly with biomaterial and fibronectin, in the presence of basic fibroblast growth factor.

This review discusses the chemical effects of UV radiation on hair, hair photoaging, and photoprotective measures, and calls for more focused research in hair photoprotection as a field.

In this study, androgen receptors were found only in the mane follicles of red deer stags during the breeding season, suggesting their expression is induced by seasonal hormone changes.
