This review argues that the immunocompetence hypothesis, linking masculine facial features to attractiveness through health benefits, lacks sufficient evidence and sidesteps alternative explanations.

This review discusses immune privilege in anagen hair follicles and its collapse in alopecia areata, emphasizing the importance of restoring this function for effective management and disease relapse prevention.

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.

This review examines current knowledge on human epithelial hair follicle stem cells, their markers, and outlines challenges in translating findings from murine studies to human research, but does not report new experimental results.

This study found that PGF2alpha analogues and PGE2 stimulated hair follicle activity in mice, with PGF2alpha analogues also linked to potential side effects like poliosis when used as eye treatments.

This review discusses neural mechanisms involved in hair growth control, focusing on piloneural interactions, but reports no clinical findings; the authors suggest further exploration for managing hair growth disorders.

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 study in the Arab population of Gaza described pseudohermaphroditism due to 17β-HSD deficiency, where individuals showed marked masculinization after puberty despite inadequate androgen proportions.

In this study, the researchers observed that male pattern alopecia is characterized by miniature follicles, enlarged sebaceous glands, and an increased number of mast cells, without significant abnormalities in enzyme activity.

In this study, caffeine applied in a shampoo penetrated hair follicles faster and more effectively than through the skin surface within the first 20 minutes.

This review summarizes advancements in forensic DNA phenotyping for appearance, ancestry, and age prediction from crime scene samples, reporting no new research findings but highlighting areas needing further research and validation.

In randomized controlled trials, this research reports that cyclosporin is as effective as glucocorticoids for treating canine atopic dermatitis and has potential benefits for other immune-mediated skin conditions in dogs.

This study found that symptom monitoring by parents of children undergoing chemotherapy identified nausea as the most common issue, with fatigue, eating problems, and fever also frequently observed.

This article proposes that alopecia areata may be caused by immune attacks on hair follicles after an immune privilege collapse, suggesting new therapeutic approaches targeting this immune response pattern.

This review discusses the importance of androgen production and metabolism in hyperandrogenism, the use of specific serum markers for diagnosis, and the need for improved assays for clinical testing, but reports no new results.

This research observed that triamcinolone was more effective at inducing remission in cats with pemphigus foliaceus without significant side effects compared to prednisone or its combination with chlorambucil.

Pregnancy often causes skin changes like darkening, stretch marks, and hair growth, which may improve after childbirth.

This study identified distinct human and bacterial protein profiles in sebaceous follicular casts, with acne samples showing proteins linked to inflammation and normal samples showing proteins involved in stress protection.

This article reviews the challenges in studying keratin proteins and emphasizes the potential of modern proteomic techniques to advance their research, but it reports no new findings.

This review discusses the neurobiology and proposed mechanisms of scalp itch, but it does not report new clinical findings, highlighting the need for further research in this area.

This study found that ZDHHC13 deficiency in mice is associated with abnormal liver function, lipid metabolism issues, and impaired mitochondrial function, highlighting ZDHHC13's regulatory role in liver metabolism.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This study found that nanostructured lipid carriers with clobetasol propionate significantly enhance follicular drug delivery compared to commercial cream, and manual massage further doubles follicular retention.

Cosmetics enhance beauty, fix defects, and intimidate enemies, with varying cultural standards and alternative methods.

This review discusses the variability and limitations of treatments for severe alopecia areata, noting some patients may achieve cosmetic hair regrowth with treatment, while others experience persistent hair loss or relapse.

This review discusses the effects of valproic acid on immune cell activation and gene expression, potentially influencing infection outcomes and suggesting its promise for autoimmune and hypersensitivity condition management.

This review discusses potential therapeutic options for frontal fibrosing alopecia by exploring distinct signaling pathways and cellular players, but reports no new clinical findings and emphasizes the need for further trials.

In this study, Geranium sibiricum L. extract promoted hair growth in vitro with human dermal papilla cells and in vivo in mice, outperforming minoxidil by proliferating cells and stimulating growth factor expression, suggesting its potential as a hair growth treatment.

This study found that procyanidin B-3, a compound isolated from barley extract, may promote hair growth by enhancing hair epithelial cell growth and counteracting TGF-β1's growth-inhibiting effects in vitro and in vivo.

This study developed a validated murine model of hypertrophic scar contraction, demonstrating similarities to human skin and observing graft contraction and tissue characteristics over time.
