This review discusses sex differences in the neuroendocrine response to stress, focusing primarily on rodent studies, and highlights open questions about the roles of gonadal hormones and sex chromosomes.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

In this study, researchers found that in late pregnancy, the neuroactive progesterone metabolite allopregnanolone inhibits HPA axis responses to immune challenges via an opioid-mediated mechanism.

This review summarizes the anatomical and physiological aspects of human hair and its clinical significance, but does not report new research findings.

This review explores the role of hormones in pilosebaceous units and associated skin disorders, focusing on androgen action, without presenting new clinical findings.

This study found that overexpression of the mineralocorticoid receptor in a mouse model led to premature epidermal barrier development, keratinocyte apoptosis, and postnatal alopecia, indicating new roles for MR signaling in skin physiology.

In this study, tofacitinib treatment was associated with significant hair regrowth in two patients with alopecia universalis over eight months, with minimal adverse effects reported.

This essay reviews the role of human scalp hair follicles in the "brain-skin connection," highlighting their dual function as targets and sources of neurohormones, without reporting new experimental results.

This study suggests that mammalian hair follicles may serve as a viable and non-invasive system for diagnosing traumatic brain injury, reflecting similar molecular responses observed in other tissues.

This study observed that the genes WNT7A, CASP7, and TNF were overexpressed in early stages of androgenetic alopecia, suggesting involvement of the WNT pathway, apoptosis, and inflammation in the disorder's development.

This review discusses the mechanisms of hair repigmentation and reports no clinical results; the authors suggest further research into topical treatments for reversing gray hair.

This book discusses current research on polycystic ovary syndrome, including diagnosis, management, and the impact of lifestyle changes, without reporting new clinical results.

This review examines the impact of biotin, vitamin B12, and zinc on male reproduction, emphasizing their role in spermatogenic failure, but reports no new clinical results.

This article reviews the impact of psychological factors on skin health and discusses the interplay between stress, the brain, and the immune system but presents no new clinical findings.

This abstract does not report specific research results but introduces a book focusing on the intersection of endocrinology and aesthetic medicine and its growing importance in contemporary clinical practice.

This review discusses the role of immune cells in the pathogenesis of alopecia areata and highlights emerging immunomodulatory strategies and novel therapeutic targets aimed at offering more effective and durable treatments for this autoimmune hair loss disorder.

This report details a six-month pharmacy internship in Portugal, where the author engaged in hospital and community pharmacy settings, and discusses scientific topics including obesity medication risks and alopecia treatment options. Results and conclusions are not explicitly reported.

This research observed that, in domestic cats like Maine Coon and Rex breeds, a "piebald" coat color pattern is likely influenced by the Silver locus, although the specific mutations involved are yet to be published.

In this review, researchers explored the complex mechanisms behind chemotherapy-induced side effects like nausea, fatigue, and hair loss, and discussed potential strategies using natural agents to manage these toxicities, improving understanding for targeted adjunct therapies.

In this animal study, hibiscus leaf simplicia ointment was found to protect red blood cell levels and promote better hair growth in UV-exposed rats, though it did not maintain normal skin histology; the ointment showed no significant acute dermal toxicity.

This review examines the role of androgens and androgen receptors in regulating glucose and lipid metabolism, focusing on their effects on mitochondrial content and function; it also discusses the sex-dimorphic influence of androgens and provides theoretical insights into their mechanisms.

This review discusses the pathophysiology of alopecia areata, highlighting the role of CD8 cytotoxic T cells and the upregulation of JAK signaling pathways; it reports no new experimental results.

This article discusses the mechanisms by which Cutibacterium acnes contributes to acne vulgaris and mentions potential triggers like UV light and tobacco, but it reports no new clinical results.

This review investigates the relationship between certain gene polymorphisms associated with obesity (FTO and MC4R) and Polycystic Ovarian Syndrome, reporting no new results but suggesting a potential genetic link.

This study found that glucose starvation and hypoxia are physiological triggers of ER stress in in vitro differentiated adipocytes, rather than high concentrations of saturated fatty acids, cholesterol, or proinflammatory cytokines.

This study reported that patients with alopecia areata have reduced expression of the melanocortin receptor MC2R in their scalp tissues compared to normal scalp, indicating potential involvement in the condition's pathophysiology.

This editorial reviews how photobiomodulation therapy might effectively treat both hyperpigmentation and depigmentation skin disorders, but reports no new clinical results.

This review discusses the role of corticotropin-releasing hormone in human skin, focusing on its regulation, receptors, and functions, and highlights parallels with the hypothalamo-pituitary-adrenal axis; it reports no new research findings.

This review discusses recent advances in understanding acne pathobiology, highlighting the potential for developing new customized therapies, but it reports no new clinical findings.

This study found that human epidermal keratinocytes express a functional μ-opiate receptor at both the mRNA and protein levels, potentially playing a role in skin physiology and pathology.
