In this study, researchers found that synchronization between expanding epithelial cells and background mesenchymal cells in the mouse hair cycle may be maintained by inhibitory regulation, with potential mediators of this regulation identified.

This review discusses current and emerging therapeutic strategies for androgenetic alopecia, noting limited evidence but suggesting areas such as prostaglandin analogs, PRP, and progenitor cell therapies as promising future directions.

This study found that mycophenolate may stabilize β-catenin and counteract interferon-γ-induced catagen changes in human dermal papilla cells, which could promote hair growth.

In this study, cyclosporine A stimulated hair growth in mouse vibrissae organ culture by promoting matrix cell proliferation and altering growth factor expression.

In this study, telogen effluvium was commonly found to be associated with iron-deficiency anemia and hypothyroidism among female patients in Makkah, Saudi Arabia.

Most women with excessive hair growth have PCOS; treatment varies and focuses on preventing new hair, with electrolysis as the only permanent removal method.

This review examines the causes, assessment, and treatment options for hirsutism but presents no new clinical findings, highlighting the need for further research on managing this condition.

This study developed a DPC cell line by introducing mutant CDK4, Cyclin D1, and TERT, making it a promising tool to study downstream signaling pathways activated by testosterone in androgenetic alopecia.

In this study, microarray and proteomic analyses indicated that genes involved in immune response, receptor binding, and growth factor activity might influence wool fibre diameter in sheep.

This study suggests that EDA-A2 induces apoptosis in hair follicles by increasing DKK-1 expression, implicating EDA2R signaling as a potential therapeutic target for androgenetic alopecia.

This chapter reviews recent developments in vitiligo research, highlighting the role of melanocyte stem cell differentiation and oxidative stress in its management, but reports no new clinical results.

This issue reviews various reports on branding, including UK consumer attitudes towards brand extensions and company performance in 1999, but provides no new research findings.

This review analyzed 109 articles to classify skin lesions associated with COVID-19 and their frequency during the disease, but found no conclusive evidence on long-term persistence of specific types due to rarity.

This case report describes a rare occurrence of lichen planopilaris in a nine-year-old child, emphasizing the need for awareness of this condition in the pediatric population.

In this study, researchers observed that administering the minimum dose of levothyroxine to a hypothyroid Dalmatian effectively restored normal skin condition and hormonal levels, suggesting levothyroxine's potential effectiveness in managing skin changes caused by hypothyroidism in dogs.

This study found that dermoscopy is effective for distinguishing Tinea Capitis from Alopecia Areata by identifying unique trichoscopic features specific to each condition.

This study identified neprilysin as a potential target of the pharmacological agent arteannuin, which may guide future research into its clinical applications, although experimental verification is needed.

Results are not reported in this invited commentary, which discusses the benefits of proper hair restoration as addressed by Jeffrey Epstein in JAMA Facial Plastic Surgery.

This study found that the ethanolic extracts of G. glabra and Z. mauritiana roots did not prevent androgenic alopecia in a testosterone-induced animal model.

This study validated a protocol for inducing surface ectoderm differentiation from human induced pluripotent stem cells and highlighted the role of TGFβ signaling pathways in this process.

This review examines the debated link between iron deficiency and nonscarring scalp alopecia in women, offering no new clinical results but emphasizing the need for further research and well-designed trials.

This study found that androgenic alopecia at an early age was associated with a lower risk of prostate cancer, contrary to assumptions about androgens' role.

This study reports that compound heterozygous loss-of-function mutations in the HEPHL1 gene in a child were associated with abnormal hair and cognitive issues, linking altered ferroxidase activity to hair disorders.

This study found that late-onset alopecia areata is more common in women and tends to present with milder symptoms, with some patients achieving complete hair regrowth in mild cases.

In this study, researchers found that cytokine dysregulation linked to genetic background is present in both patients and healthy but genetically related individuals in two autoimmune skin diseases, Pemphigus vulgaris and Alopecia areata, suggesting that protective immune mechanisms may prevent disease manifestation in predisposed individuals.

This study suggests that dsRNA may enhance KRT9 expression in palm and sole skin through β-catenin signaling, potentially linking mechanical damage to specific skin features and certain skin conditions.

This article discusses various potential causes of hair loss in women undergoing renal replacement therapy and emphasizes the importance of thorough patient evaluation, but it reports no new research findings.

Activating Wnt in skin cells controls the number of hair follicles by directing cell movement and fate.

In this study, pantothenic acid at 20 μg/ml was observed to promote dermal papilla cell proliferation and migration, likely through up-regulation of ID3 and inhibition of Notch signaling.

This review discusses the role of keratins in epithelial cell stress protection and cancer, highlighting their potential as multifunctional regulators and diagnostic markers, without presenting new research findings.
