In this study, chronic unpredictable stress affected male and female wild-derived house mice differently; stressed females gained less weight, had long grooming times, and lower immobility in tests, while stressed males showed increased hair corticosterone levels and shorter immobility times.

In this study, researchers found that topical treatment with adenosine improved hair growth and thickness by significantly increasing hair density and thickness after four months in vivo, with results comparable to minoxidil, potentially due to adenosine's anti-androgenic effects.

This study is the first to detail major geriatric diseases in aged Julia Creek dunnarts, particularly highlighting hormonal issues like cystic glandular hyperplasia in females and testicular degeneration in males, suggesting these conditions are linked to aging and potentially hormonal dysregulation.

In this review, it is discussed how mesenchymal stem cell aggregation plays a crucial role in organ development and has potential applications in organ regeneration through tissue engineering.

This study suggests that post-finasteride syndrome and post-SSRI sexual dysfunction share potential etiopathogenetic mechanisms involving brain modulators, neurotransmitters, and gut microbiota, although more research is needed to understand these conditions fully.

This review discusses the potential of low-dose oral minoxidil as a safe and effective treatment for certain hair disorders, including alopecia, but reports no new clinical results.

This review compiles existing information on the pathogenesis of androgenetic alopecia, highlighting its genetic, hormonal, and environmental factors, but reports no new clinical findings.

This study identified a novel genetic mutation, c.429delC in the hairless gene, associated with atrichia with papular lesions in two Pakistani families.

In this study, topical application of tonic preparations containing 5% ethanol extract of Phyllanthus niruri to shaved mice showed potential as a hair growth enhancer, as indicated by observations of increased hair length and weight over a 21-day period.

This review outlines the physiological roles of 5a-reductases and highlights the need for further research to better understand their function and minimize adverse effects from their inhibitors used in treatment.

This review highlights the importance of standardizing pre-analytical procedures for collecting and extracting samples from uncommon biological specimens like breast milk and sweat in clinical metabolomics, to enhance diagnostic and biomarker discovery efforts while minimizing contamination and bias.

This review discusses the use of hair cortisol concentration as a marker for chronic stress and long-term cortisol secretion in animals, highlighting its benefits and the need for standardized sampling protocols.

This study found that in lactating Holstein cows, hair from the tail switch, which grows faster and is more sensitive to cortisol changes, is ideal for measuring hair cortisol levels.

This study found that in vitro, beard dermal papilla cells stimulated keratinocyte proliferation via androgen-dependent growth factors, while androgenetic alopecia cells released TGF-β1, inhibiting keratinocyte growth.

This review examines alopecia, its causes, the impact of micronutrients, and the role of the Mediterranean diet, noting conflicting data and a need for more research on diet's effect on hair loss.

This study found that cortisol concentrations were significantly higher in hair samples with follicles compared to those without, suggesting potential confounding in stress assessments using different hair sampling methods.

This study found that among individuals with hair loss-related conditions, there was a significant association between alopecia and anxiety disorders, with affected individuals experiencing anxiety more frequently.

In this study, Glycine soja Siebold et Zucc extracts promoted hair growth and increased cell activity in mice, suggesting potential use for alopecia treatment.

This study found that oral administration of solubilized sturgeon oil in mice promoted hair growth and positively influenced the gut microbiome associated with hair growth promotion.

This review examined and discussed the role of dermis-derived factors in the regulation of melanogenesis, noting their significance in both normal and abnormal mammalian skin conditions, suggesting an underexplored area of study compared to dermal and epidermal influences.

This study observed that management practices affect alopecia and hair cortisol in captive rhesus monkeys, with variations in these effects between different facilities.

This study found that social hair plucking in captive rhesus macaques may share traits with both prosocial and aggressive behaviors and is associated with alopecia and hair cortisol levels.

In this study, alopecia was more common among pregnant rhesus macaques compared to non-pregnant controls, and pregnancy was associated with increased hair cortisol levels.

This study concluded that coat damage in captive rhesus macaques is unlikely caused by parasitic, bacterial, or mycotic infections but may be linked to environmental or behavioral factors affecting hair growth.

In this study of captive rhesus macaques, social hair plucking was related to kinship, showed characteristics of both prosocial and aggressive behaviors, and was associated with alopecia and hair cortisol concentrations in females.

This study observed that in captive rhesus macaques, social hair plucking is linked to alopecia and has kinship patterns similar to grooming, suggesting it may be socially influenced, though the health impacts and stress hormone (cortisol) changes involved remain uncertain.

This review discusses alopecia in nonhuman primates in research settings and reports no new findings, emphasizing documentation and therapeutic intervention importance during regulatory inspections.
