This research found that kaempferol, a flavonoid from hair growth-promoting plants, significantly enhanced human dermal papilla cell proliferation and inhibited specific signaling pathways, outperforming minoxidil, with topical application in mice promoting hair growth and thickness, indicating potential as a natural hair loss treatment.

This study highlights IGF-1's role in promoting hair follicle proliferation, vascularization, and growth, suggesting its potential as a treatment target for hair loss disorders like androgenetic alopecia, though more research on delivery methods and long-term effects is needed.

This study outlines a multidisciplinary approach to investigate primary amenorrhea, emphasizing the necessity to consider medical history, physical examination, and potential hormonal or anatomical causes, and recommends early referral in cases of chromosomal abnormalities or persistent amenorrhea following the development of secondary sexual characteristics.

This study found that in mice, oral administration of Lactilactobacillus curvatus LB-P9 accelerated hair regrowth and increased hair thickness, hair follicle numbers, and dermal thickness, likely by boosting hair growth factor production and dermal papilla proliferation.

Acne is linked to inflammation and insulin resistance, and is associated with various syndromes that require different treatments.

In this study, topical tofacitinib significantly promoted hair regrowth in mice, outpacing both minoxidil and controls over 21 days, with findings suggesting increased VEGF levels and decreased inflammation as possible mechanisms.

This review discusses the interplay between epilepsy and reproductive endocrine disorders, examining the factors involved and emphasizing the importance of monitoring but reports no new research findings.

This review analyzes how androgens impact sexual desire and reproductive behaviors, emphasizing molecular interactions, but provides no new clinical results.

This study found that medroxyprogesterone injections led to partial or complete hair regrowth in some Pomeranian dogs with alopecia X, though their IGF-1 levels remained unchanged.

This article reviews the role of androgens and oral contraceptives in acne pathogenesis and management but presents no new clinical results.

This study in mice found that WWP2 facilitates odontoblast differentiation and dentin formation by targeting PTEN for degradation, thereby enhancing KLF5 activity, which may suggest its crucial role in dental development.

The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.

In this narrative hypothesis-driven overview, the authors propose reframing rosacea as a neuroimmune disorder, highlighting the interconnected role of the skin-gut-brain axis, particularly central nervous system involvement alongside gut microbiota and neurogenic inflammation, to emphasize the need for multidisciplinary therapeutic approaches.

This literature review examined research on hair follicle biology and hair loss treatments, highlighting the potential of secretome-based therapies, which may enhance hair regeneration and address limitations of treatments like minoxidil and finasteride.

In this study, researchers found that caffeine can counteract stress-induced damage in ex vivo human androgenetic alopecia hair follicles, suggesting it may help prevent stress-related hair loss.

This study identified that bone marrow-derived CD34⁺ cells act as fibroblast progenitors to enhance tissue regeneration in ischemic limbs by promoting angiogenesis through interactions with macrophages.

This study found that prenatal exposure to fluoride and lead, as well as maternal micronutrient intake, may influence sexual maturation in adolescents in a sex-specific manner.

This review explores the complex endocrine functions of human skin and its role as a peripheral endocrine organ, but reports no new clinical results.

In this study, pioglitazone treatment in insulin-resistant PCOS patients decreased relative 5alpha-reductase activity without significantly affecting cortisol levels or urinary cortisol excretion.

This study found that 3-hydroxypropionic acid improved the function of hair follicle cells under oxidative stress, suggesting potential as a treatment for stress-related hair loss.

Nutrition plays a key role in managing skin disorders, with specific dietary changes helping improve conditions like acne, dermatitis, psoriasis, alopecia, and skin cancer.

This article reviews the role of IGF-1 in acne pathogenesis and discusses how diet and smoking may influence insulin/IGF-1 signaling, but reports no new clinical results.

This study discusses how redox imbalance, specifically through reduced Insulin-like Growth Factor-1 mediated by the transcription factor JunB and sphingolipid metabolism changes, contributes to skin aging by depleting stem cell pools and altering the extracellular matrix, ultimately impacting skin integrity and function.

This study found that black cohosh extract BNO 1055 reduced testosterone-induced prostate and seminal vesicle growth in rats, suggesting it may contain potent 5α-reductase inhibitors useful for prostate cancer prevention.

This review explores the potential link between psoriasis and metabolic syndrome, focusing on how disturbances in growth factors may connect these conditions and contribute to symptoms like keratinocyte proliferation and inflammation.

In this study on mice, elevated IGF-1 levels in the skin were linked to premature aging of hair follicles, but interventions like reducing IGF-1 or using senolytic treatments helped restore stem cell health and counteract aging effects.

This review discusses the effects of IGF-1 on hair follicle cell proliferation and differentiation, highlighting its roles in paracrine signaling, apoptosis prevention, and hair growth, but reports no new clinical results.

This study found that selenium deficiency in mice accelerated age-related conditions and metabolic decline but unexpectedly promoted longevity, suggesting low selenium levels might separate healthspan and lifespan.

This review discusses psychological impacts associated with facial acne, noting that high levels of anxiety and depression among these patients are not linked to oxidative stress, and reports no new clinical results.

This study observed that certain herbal extracts may promote hair growth and inhibit hair loss in cell lines by affecting specific protein expressions similarly to minoxidil.
