In this study, administering 5alpha-reductase inhibitors reduced dihydrotestosterone levels and was associated with mild, reversible decreases in semen parameters in healthy men.

Genetic variation in the androgen receptor gene mainly causes early-onset hair loss, with maternal inheritance playing a key role.

This review discusses the diagnosis and treatment of hirsutism, emphasizing that a systematic evaluation can determine its cause, while combination therapy effectively manages the condition for most patients.

This study found that psychoemotional stress disrupts hair growth in mice by terminating anagen and suggests a potential pathway for pharmacological management of stress-related hair loss in humans.

This review discusses strategies for developing semi-solid topical generic products to match the quality of reference-listed drugs, using concepts like quality by design and reverse-engineering, but reports no new results.

This review discusses alopecia areata as a model for studying tissue-directed autoimmune diseases and reports no new clinical findings.

This review discusses various therapeutic strategies targeting platelet-derived growth factor signaling in diseases like cancer and atherosclerosis, and evaluates existing treatments without presenting new clinical data.

This review discusses the role of jumonji family proteins in chromatin regulation and development, highlighting their involvement in transcriptional repression and histone demethylation, but reports no new experimental findings.

This study identified a distinct cytokine activation signature in alopecia areata, involving TH2, TH1, IL-23, and IL-9/TH9 pathways, suggesting potential targeting strategies similar to those in psoriasis and atopic dermatitis.

This review summarizes the roles of bone morphogenetic proteins in the development and regulation of normal and diseased skin, but it does not provide new clinical results.

This article discusses the cutaneous side effects of various chemotherapeutic agents but reports no new clinical results; the authors emphasize the importance of dermatologists recognizing drug-induced skin reactions to better patient care.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

This study found that transformation expectations mediate the link between materialism and credit overuse, suggesting that materialism fosters favorable attitudes toward debt and beliefs in life changes through acquisition.

This review of interventions for alopecia areata found no significant treatment benefits for hair growth compared to placebo, indicating a need for larger, well-conducted studies.

This study suggests that stress negatively affects hair growth by inducing inflammation and early hair cycle transitions in mice, which might inform strategies for managing stress-related hair loss in humans.

This study found that latanoprost induces significant growth and pigmentation of lashes and ancillary hairs, with effects mirroring both brief and chronic treatments observed in patients and animal models.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This literature study reviews the consequences of hair loss due to chemotherapy and nursing care interventions but reports no new clinical results.

This study found that DrugNet, a network-based prioritization method, effectively improves drug repositioning tasks, achieving high performance in validation tests and clinical trial comparisons.

This study reports that some patients with androgenetic alopecia may also exhibit clinical and histological features of inflammation and fibrosis, similar to those found in lichen planopilaris.

This review discusses the development of an interdisciplinary guideline on Post-COVID/Long-COVID symptoms, diagnostics, and therapies by the Deutsche Gesellschaft für Pneumologie, reporting no new results but highlighting ongoing updates based on emerging knowledge.

This review examines recent advances in understanding the pathophysiology and molecular mechanisms of androgenetic alopecia, highlighting two major genetic risk loci, but does not report new clinical findings.

This review discusses the use of caffeine in cosmetics for its fat-reducing, antioxidant, and hair growth properties, but reports no new research findings.

This paper introduces the Follicular Unit Extraction procedure and its accompanying FOX Test, finding that 60% of tested patients were suitable candidates for this minimally invasive hair transplantation method.

In a neonatal rat model, this study found that topical CDK2 inhibitors reduced chemotherapy-induced hair loss in 33 to 50% of the animals, suggesting a potential strategy for preventing alopecia in cancer patients.

Humans lost body hair relatively recently in evolution.

This guideline reviews the diagnosis of androgenetic alopecia and offers expert consensus recommendations tailored to males, females, and adolescents, but reports no new clinical results.

This study suggests that antiandrogens may slightly reduce hirsutism severity compared to placebo, but evidence is weak and their relative efficacy remains uncertain.

Minoxidil works better for female hair loss, but cyproterone reduces scalp oiliness and causes menstrual issues.
