This study identified somatostatin as a potential secretory factor contributing to the immune privilege of human hair follicles.

This study utilized a sequence-structure alignment approach to improve the characterization of Class A Rhodopsin GPCR superfamily, including orphan and unclassified receptors, through evolutionary analysis.

This article describes a case of oral pigmentation that posed a diagnostic challenge in determining Addison’s disease and includes a brief review, reporting no new clinical results.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

Melatonin affects when and how goat hair follicle genes turn on and off during growth cycles.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This review discusses the profound impact of obesity on skin physiology and dermatologic conditions and reports no new experimental results, recommending awareness and treatment strategy development for obesity-associated dermatoses.

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 article discusses the role of human hair follicles in neuroendocrinology and suggests potential new therapeutic targets by examining how neuromediators influence hair growth, pigmentation, and stem cell biology in organ cultures.

This review summarizes recent multidisciplinary advances in sebaceous gland research and highlights potential novel therapeutic strategies for skin diseases, but it reports no new clinical results.

This review examines the differential aging of melanocytes in hair follicles and skin, and reports no new findings; the authors suggest further research is needed to understand these processes.

This review discusses various skin diseases with endocrinological origins and reports no clinical results, highlighting the need for interdisciplinary understanding in diagnosis.

In this study with organ-cultured human scalp hair follicles, high mTORC1 activity correlated with gray/white hair and reduced pigmentation, while inhibiting mTORC1 with rapamycin increased hair growth and pigmentation, suggesting mTORC1 inhibition could be a strategy for treating hair depigmentation and loss.

Light therapy can effectively treat vitiligo and hair loss caused by a specific medication.

This research found that androgen bioactivity plays a role in normal female sexual differentiation, suggesting females develop within a significant androgenic environment, with implications for understanding conditions like congenital adrenal hyperplasia.

This study found that normal murine hair follicles are direct targets for melatonin bioregulation, expressing receptors that are regulated in a hair cycle-dependent manner, influencing keratinocyte apoptosis.

In this study, researchers developed a method for high-resolution live imaging of leg regeneration in the crustacean Parhyale hawaiensis, which effectively captures the entire process at cellular resolution over 10 days while minimizing photodamage.

This review highlights the possibility of safely altering hair color through innovative cosmetics by targeting key biological processes in hair follicles, using insights from mammalian pigmentation studies and drug-induced hair color changes as potential pathways.

This study found that Centipeda minima extract promotes hair growth by activating Wnt/β-catenin, ERK, and JNK signaling pathways in human hair follicle dermal papilla cells.

This review discusses how targeting apoptosis pathways in hair and skin cells can inform the development of novel therapies, but it reports no clinical findings.

This review discusses insights into the role of lipase H in controlling hair form and texture, emphasizing genetic mutations linked to autosomal recessive woolly hair/hypotrichosis, and reports no new experimental results.

Ganoderma lucidum extract may help treat stress-related hair loss.

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.

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.

This article reviews the pathogenesis and treatment approaches for premature graying of hair, noting the unsatisfactory options currently available, and reports no new clinical findings.

TEDAR is crucial for skin cell differentiation and barrier formation.

This study examined gene expression in cashmere goats and identified key pathways and molecular regulators that influence hair follicle growth stages and melatonin's role in promoting cashmere growth.

This study found that human scalp hair follicles can respond to corticotropin releasing hormone stimulation similarly to the classical HPA axis, including up-regulating cortisol production and activating neuroendocrine feedback loops.

This study found that human hair follicles can function like a peripheral hypothalamic-pituitary-adrenal axis, synthesizing cortisol in response to corticotropin-releasing hormone and adrenocorticotropic hormone stimulation.

The combination of a plant extract and a peptide can increase hair pigmentation and may reverse greying.
