This study concluded that a combination of millet seed extract, L-cystine, and calcium pantothenate may improve anagen hair rate in women with androgenetic alopecia over six months.

This study found that a new oral supplement with sulfurated amino acids and trace elements effectively improved hair growth and reduced hair loss in women with telogen effluvium and mild to moderate androgenetic alopecia.

This issue contains notes by Dr. Bradley Wolf and mentions comments by Dr. Jerry Cooley, but it presents no new research findings.

This study developed and validated a method to analyze active ingredients in hair nourisher products, which was successfully applied to products from the market.

This study developed and validated a method to analyze active ingredients like nicotinamide and tocopherol in hair nourisher products using HPLC, which may facilitate quicker market access for these products.

The researchers reported that a novel leave-on treatment containing caffeine, niacinamide, panthenol, dimethicone, and an acrylate polymer significantly increased the diameter and improved the mechanical properties of scalp hair fibers, suggesting it may help mitigate thinning hair.

This case report described an 8-year-old Chihuahua with significant hair loss, where supplementation with horse placenta extract, taurine, and vitamin B complex led to marked hair regrowth and maintained coverage during a 76-week follow-up period, suggesting a potential non-invasive treatment option for alopecia in dogs.

In this study, Pilopeptan® Intensive, a nutritional supplement containing hydrolyzed collagen, Group B vitamins, and zinc, was found to significantly improve hair parameters in telogen effluvium patients, with sustained benefits observed posttreatment, although mild side effects were reported by some participants.

This study observed that pantethine, a vitamin B5 precursor, attenuates tumor growth in immunocompetent mice by enhancing antitumor immunity, but its effect is limited by immune cell exhaustion over time.

This study demonstrated that combining l-cystine and thiamin in a formulation may protect against UV-induced damage in growth-limited human epidermal keratinocytes in vitro.

This paper offers a detailed overview of B vitamins, detailing their importance for energy, cognition, and metabolism, conditions leading to their deficiencies, symptoms of deficiencies, and the foods rich in these essential nutrients.

This study found that hemodialysis patients taking water-soluble vitamins had a 16% lower mortality risk compared to those not taking any, but the specific supplementation needed remains unclear.

This study found that multiple vitamins, including B6, increased the number of growing follicles in newborn mouse ovaries in vitro. VB6 promoted primordial follicle activation via the PI3K/Akt signaling pathway in both cultured mouse and human ovarian tissues.

This review discusses the role of vitamin D metabolism in skin immunity and wound healing but does not present new results, highlighting the need for further research into its therapeutic applications.

This article discusses how vitamin D supplementation impacts human aesthetics and health, with effects varying positively or negatively based on different dermatological conditions.

This review discusses the potential role of vitamins and minerals in managing non-scarring alopecia but reports no clinical results; the authors advocate for further controlled trials to explore these relationships.

This review discusses the potential role of vitamin D deficiency in cardiovascular and renal diseases and suggests that supplemental vitamin D could benefit cardiovascular outcomes, especially in African American and postmenopausal women; it reports no new clinical findings.

This study demonstrated that an LC/MS-MS method could effectively detect and quantify the vitamin B3 vitamer nicotinamide in human hair, suggesting its potential use for long-term deficiency examination.

The researchers reported that the antipsoriatic compounds 1,25-dihydroxy-vitamin D3 and calcipotriol thinned the living cell compartment in organotypic ORS cultures by accelerating the differentiation pathway rather than affecting proliferation.

This study found that activin B promotes the initiation and development of hair follicles in both cultured and neonatal mouse skin models.

In this review, the authors summarized the neuroprotective role of water- and fat-soluble vitamins in neurodegenerative diseases, highlighting their potential preventive and therapeutic effects through antioxidant and anti-inflammatory properties while acknowledging some studies question their preventive influence.

This review found that while vitamin supplementation may improve hair health in individuals with deficiencies, there is limited evidence to support its benefits for those with healthy baseline hair.

This paper presents a case where vitamin D replacement therapy was associated with hair regrowth in a patient with nonscarring alopecia linked solely to vitamin D deficiency and discusses managing vitamin D deficiency more broadly.

This article discusses factors influencing hair greying, such as thyroid hormone levels and postmenopausal changes, and suggests lifestyle adjustments for hair health; it reports no new clinical findings.

This study found that adding 10 mg/day of biotin to isotretinoin treatment for acne improved hair growth and maintained skin hydration, potentially reducing isotretinoin's mucocutaneous side effects.

This review examines complementary and alternative medicine for alopecia and finds limited support from robust clinical trials, highlighting the need for standardized studies to evaluate efficacy and safety.

In this study, VD(3) pretreatment increased hair follicle formation in a rat model by promoting dermal papilla cell differentiation, suggesting potential for hair regeneration therapy.

This review discusses medication-induced gray hair repigmentation, highlighting that certain anti-inflammatory drugs and melanogenesis stimulators can cause diffuse repigmentation, though evidence remains low-quality and these medications are not currently indicated for this purpose.

This review discusses environmental factors like UV radiation and smoking that affect hair health and highlights the potential role of nutrition, but it reports no new results.

This review discusses the role of diet in managing hair loss during menopause and reports no new clinical results; it highlights the importance of nutrients like sulfur amino acids, vitamins, and minerals.
