Men with a certain type of hair loss (AGA) have higher bad cholesterol and lower good cholesterol levels, making them more likely to get heart disease.

This study suggests that greater sensitivity to androgens, as indicated by higher than grade 2 androgenic alopecia, may reduce the risk of schizophrenia by 8.62 times.

This meta-analysis reports that 5-alpha-reductase inhibitors are associated with a 31% increased risk of depression, with varying outcomes depending on the comparator group, highlighting significant heterogeneity across studies.

Results are not reported in this commentary, but it discusses the influence of different control group choices—an active-comparator versus non-drug users—on measuring depression risk in studies of 5-alpha reductase inhibitors.

This study found that patients with frontal fibrosing alopecia had higher hair shaft concentrations of titanium, zinc, aluminum, and iron, possibly linked to the use of metal-containing products.

This study concluded that iron deficiency is common among women but not more prevalent in those with female pattern hair loss or chronic telogen effluvium compared to control subjects without hair loss.

This study examined the demographics of patients diagnosed with pernio and compared their vitamin B12, folate, and ferritin levels with those of a control group.

The levels of zinc, vitamin D, ferritin, and selenium are different in people with androgenic alopecia compared to a control group.

No significant difference in iron deficiency between women with or without hair loss.

This review examines how epigenetic dysregulation affects adult stem cell function, noting that impacts range from minor to serious disruptions in tissue homeostasis and potential cancer development.

This consensus report reviews current knowledge and identifies knowledge gaps concerning the various health aspects of polycystic ovary syndrome, without presenting new clinical findings.

This study found that control of Demodex mite colonization in mice required skin ILC2s and IL-13, highlighting their role in maintaining HF integrity and limiting mite overgrowth.

This study found that type 2 immunity, especially involving ILC2 cells, helps maintain skin homeostasis by regulating the proliferation and community stability of hair follicle epithelial cells in the presence of Demodex mites.

This study reports that women with polycystic ovary syndrome, especially those with a hyperandrogenic pattern, are at a higher risk for cardiovascular disease compared to other PCOS patients, likely due to related metabolic comorbidities.

This study found that combining letrozole with metformin was more effective at inducing pregnancy in women with PCOS compared to letrozole alone, while OCP and metformin significantly improved menstrual regularity and reduced hyperandrogenic symptoms.

This study did not report conclusive results on whether a higher dose of platelets in platelet-rich plasma treatment impacts hair density, emphasizing the need for further evaluation of the trial details.

This study demonstrated that Ketoconazole, Minoxidil, and Minoxidil with Tretinoin all significantly stimulated hair growth in mice, with Minoxidil alone showing the most effectiveness.

This study found that in a shaving animal model of mice, increased enzyme activities and gene expression correlated with enhanced hair growth, suggesting they are good biomarkers in the anagen phase.

This study found that using senseviera hair tonic significantly increased hair density among women aged 19-25 who wear hijabs.

This study found that patients with alopecia areata had a higher frequency of the AB+ blood group compared to healthy controls.

The researchers reported that differences in brain functional connectivity between unmedicated seasonal affective disorder patients and healthy controls vary with ICA model order, peaking in volume at model order 70.

This study found that finasteride use for androgenetic alopecia was not associated with increased sexual dysfunction compared to an age-matched control group.

In this study, researchers reported no significant association between ABO or Rh blood groups and the incidence of hidradenitis suppurativa among patients compared to healthy controls.

This study found that synthetic ceramide shampoo improved dandruff and erythema while reducing water loss when compared to control in a group of 20 subjects over four weeks.

In this study of patients with alopecia areata, researchers found that although serum vitamin A levels were lower compared to controls, the difference was not statistically significant. However, stress levels were significantly higher in the alopecia areata group.

In this study, researchers found that although vitamin D deficiency was common among patients with non-scarring alopecia, the prevalence of vitamin D insufficiency was also comparable in the control group, suggesting a need for community-level vitamin D fortification.

This study found a significant association between early onset androgenetic alopecia and metabolic syndrome, with higher prevalence of metabolic risk factors in affected individuals compared to a control group.

This study found that female patients with acne had significantly higher insulin resistance compared to a control group without acne, suggesting that acne could serve as an early clinical marker of insulin resistance in women of reproductive age.

In this pilot study on treating dorsal wrist ganglion, PRP injection showed limited effectiveness at 1-year follow-up compared to aspiration alone, with most PRP-treated patients experiencing ganglion recurrence, suggesting that an RCT would need at least 46 patients per group to further assess PRP's utility.

In this theoretical study, axolotl spinal cord regeneration was modeled using a reaction-diffusion process, suggesting that the control of regenerative response relies on cell sensitivity to the signal and its diffusion characteristics, laying groundwork for identifying the signaling mechanism.
