This study discusses the complex roles and effects of brain-synthesized sex neurosteroids, highlighting sex differences in their concentrations and their varied impacts on synaptic plasticity, cognitive behavior, and aging-related cognitive decline.

This review analyzed scientific literature and found that dermatological symptoms, such as hirsutism and acne, frequently appear as early indicators of PCOS, reflecting hormonal imbalances and aiding diagnosis of the disorder.

This report identified a family of Iranian siblings with diverse clinical forms of Lichen Planus, suggesting potential genetic and environmental involvement in its pathogenesis.

This study found that the prenatal skin development in Red Sokoto goats undergoes significant morphological changes across gestational stages, which may be important for their adaptation and thermoregulation after birth.

This review highlights the hair follicle's structural and functional properties as an effective route for delivering active compounds in treating hair disorders, focusing on emerging carrier technologies to enhance targeted transfollicular delivery.

In this study, researchers found that the lipid composition in hair significantly affects water diffusion and may explain differences in dyeing and cosmetic treatment responses between Asian and European hair, with CP2 fibers having more lipids than CP3 fibers.

Elevated luteinizing hormone contributes to female-pattern hair loss, and blocking certain channels may help prevent it.

The testes significantly contribute to vitamin D metabolism and may affect male reproductive health and conditions like hair loss.

This study used Mendelian randomization to explore associations between 1400 blood metabolites and female-pattern hair loss, finding 23 metabolites and 4 metabolic ratios linked to the condition, while identifying fructose/mannose metabolism as a significant pathway.

This article reports the first documented cases of Marie-Unna hereditary hypotrichosis in Egypt, highlighting the variability of genetic mutations in this rare form of congenital hair loss.

This study found both topical spironolactone and topical minoxidil to be effective and safe treatments for female pattern hair loss, with mild to marked improvement observed over six months in both treatment groups, though more side effects were noted with minoxidil.

In this case series study, two Peruvian women with virilizing ovarian tumors called Sertoli-Leydig cell tumors showed clinical improvement and normalization of androgens after surgical treatment, highlighting the diagnostic challenge of these rare presentations at different ages.

This randomized control trial reported that mesenchymal stem cell-derived exosomes significantly increased hair density and thickness in patients with androgenic alopecia, with a mean increase of 35 hairs/cm² over 12 weeks compared to the placebo group, which showed minimal hair density changes.

This study found a significant association between increased waist circumference and body mass index and female pattern hair loss in premenopausal women, suggesting the importance of screening for metabolic syndrome in these patients.

This study characterizes alopecia in ARCI, highlighting its prevalence among patients with severe forms and revealing new associated trichoscopic features.

This study found that 18-β-Glycyrrhetinic acid, a licorice component, stimulated human hair follicle cell proliferation, inhibited testosterone 5α-reductase, and suppressed TGF-β1, suggesting potential for treating androgenetic alopecia by promoting hair growth and prolonging the anagen phase.

This article evaluated evidence on finasteride's effects on male reproductive health, finding contradictory data about its adverse effects, but consensus that such cases are infrequent in research and clinical settings.

This study found that a 2-deoxy-D-ribose gel stimulated hair follicle growth in mice with androgenic alopecia, showing effects similar to minoxidil without additional benefits from combining the two treatments.

This study found that three sessions of injectable platelet-rich fibrin (i-PRF+) significantly improved hair follicle density, hair volume, and thickness, as well as patient satisfaction in women with female pattern hair loss, with only minor self-limited adverse effects reported.

This systematic review reported that PCOS is marked by increased androgens, hirsutism, and an elevated LH/FSH ratio, with metformin showing a therapeutic effect on menstrual cycles, emphasizing the need for individualized treatment strategies.

The study found that combining a 655nm low-level laser helmet with 2% minoxidil resulted in better improvement in hair diameter and intermediate hair enlargement at the midscalp among Chinese women with FPHL.

This review discusses recent findings on how root hairs and root exudate secretion play critical roles in recruiting nitrogen-fixing bacteria, potentially aiding the development of cereal crops that can use atmospheric nitrogen, which may reduce reliance on synthetic fertilizers.

This study observed that among 120 patients recovering from COVID-19, severe diffuse hair loss typically began less than two months post-infection, with the majority of patients experiencing a severe degree of hair loss and positive hair pull tests, often alongside vitamin D deficiency.

This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This study describes the use of a genetically engineered mouse model, mTurquoise2-Col4a1, to fluorescently label collagen IV and observe basement membrane dynamics during skin development, revealing its stability and pliability during rapid growth phases.

In this study, the researchers found that rare genetic variants make a minor contribution to male-pattern hair loss risk, identifying five significant gene associations, including novel genes, and noting a shared basis with monogenic hair loss disorders.

This case report describes a 35-year-old woman with PCOS who achieved a healthy pregnancy and symptom relief through a four-month Ayurvedic treatment regimen, emphasizing its potential in treating severe cases.

This study found that lateral root formation in plants in response to L. bicolor volatiles involves complex signaling processes, potentially including unknown proteins, CRKs, and ABA pathways.

This review discusses the role of neurosteroids and androgens throughout different life stages, noting the potential disruptions caused by 5α-reductase inhibitors like finasteride, but no new clinical results are reported.

This article discusses the impact of COVID-19 on skin health, highlighting various cutaneous manifestations and the need for dermatologists to adapt their practices during the pandemic, but it reports no new results.
