This letter discusses the use of serial trichoscopy versus a modified hair pull test for monitoring localized alopecia areata but reports no new clinical results.

This study found that women with female-pattern hair loss had significantly lower serum levels of 25-hydroxyvitamin D compared to healthy controls, but it does not establish causation.

Mutations in the Sgk3 gene cause fuzzy hair in mice.

This study found that a serum-free culture system supported hair growth from follicles responsive to calcium, glucose, and amino acids, with insulin enhancing the growth, while other factors had no effect.

Finasteride increases hair growth, prolongs hair cycle, and lowers dihydrotestosterone levels.

This study found that variations in sleep patterns, free testosterone, and 5-alpha-reductase type 1 activity are associated with changes in sebum excretion in women, which may contribute to variability in acne studies.

This study found that tralokinumab effectively reduced the severity of moderate-to-severe atopic dermatitis over 28 weeks in adults, with significant improvements in clinical outcomes and biological markers, although 27.4% of patients discontinued treatment due to adverse events or ineffectiveness.

This study found that serum 25-hydroxyvitamin D was inversely associated with serum ferritin levels in Korean men, positively associated in premenopausal women, and not associated in postmenopausal women.

This study found no significant association between serum levels of vitamin B12, folate, TSH, ferritin, zinc, or anxiety scores and trichodynia in telogen alopecia patients.

This study found that a 400-mg dose of oral testosterone with dutasteride increases serum testosterone levels for 8–10 hours in hypogonadal men, with the nanomilled formulation unaffected by food, suggesting a practical twice-daily therapy option.

This article challenges the idea that low serum ferritin is not associated with chronic diffuse telogen hair loss by questioning the validity of 'normal' serum ferritin reference ranges.

This study found that in women with acne vulgaris, lower serum levels of 3α-androstanediol-glucuronide suggest reduced 5α-reductase activity compared to controls, indicating that 5α-reductase inhibitors may not be effective for acne treatment.

This study found that mutations in the Sgk3 gene cause defective hair follicle development and altered hair cycling in mice, with variable phenotypic outcomes depending on different dysfunction patterns of the SGK3 protein.

In this study, oral finasteride therapy was associated with decreased DHT levels and improved hair loss severity in young male AGA patients, while hormonal changes influenced the curative effect.

Blood AMH levels are higher in women with PCOS than in those with other similar conditions.

This study found an association between low serum ferritin levels and alopecia in women, suggesting a potential role of iron in hair health and paving the way for further research.

This study found that serum zinc levels were lower in PCOS subjects compared to normal controls, suggesting zinc may play a vital role in PCOS pathophysiology.

This article describes the immunofluorescence tomography method to achieve high-resolution 3-D reconstruction of epithelial tissues and reports no clinical results.

This study found a significant correlation between vitamin D deficiency and the severity of androgenetic alopecia in males, suggesting that vitamin D may influence the condition's premature onset.

This study found that serum irisin levels were significantly lower in patients with acne vulgaris compared to healthy controls and were negatively correlated with insulin resistance and disease severity.

High protein diets improve wound healing and hair growth in calves, regardless of energy intake.

This study developed and validated a highly sensitive LC-MS/MS method for detecting multiple steroid hormones in urine and serum/plasma, demonstrating its potential for use in large-scale biomonitoring studies.

This study found that patients with androgenetic alopecia had increased oxidative stress and microinflammation, contributing to hair loss, due to elevated levels of specific serum biomarkers compared to controls.

This study found that lower serum vaspin levels (below 3.74ng/mL) may predict successful ovulation induction with clomiphene citrate in anovulatory women with PCOS, indicating potential resistance when levels are higher.

This study found that vitamin D was positively associated with serum ferritin levels in Korean women without metabolic syndrome, but this association was not observed in those with metabolic syndrome.

This study reported significantly lower levels of serum iron, ferritin, and calcium in young patients with premature gray hair compared to controls, implying that supplementation might prevent further graying.

This study found that the imidacloprid/flumethrin collar (Seresto®) is chemically compatible with major spot-on formulations and dermally and systemically safe for adult dogs and cats when used together.

This report discusses a case of hair toe tourniquet syndrome in an infant and emphasizes the importance of early diagnosis and treatment to prevent severe complications.

This study found that serum iron and ferritin levels in patients with alopecia areata did not significantly differ from control subjects, suggesting these factors may not contribute to the condition's etiology.

In this study, alopecia areata and vitiligo patients had significantly lower serum BDNF and vitamin D levels, which were inversely associated with depression and quality of life, suggesting a potential combined role in the development of depression.
