This study found that antibiotic-induced gut dysbiosis, particularly overgrowth of Lactobacillus murinus, can lead to hair loss in mice by depleting biotin.

In this study, the derivation of certain topological indices was used to represent the molecular structure of drugs for alopecia treatment, like Minoxidil and Finasteride, which may support medication investigations, especially in resource-limited settings.

This study suggests that biotin-rich functional food may stimulate hair growth and prevent hair loss through improved cholesterol and lipid metabolism and blood flow in men.

In this study, biotin supplementation was found to significantly increase wool follicle viability and metabolic activity in vitro, with the highest effects observed at 0.5 mg L⁻¹ concentration.

Food deprivation increases MST enzyme in the brain, possibly affecting energy balance.

This study found that glutathione deficiency affects lateral root and root hair responses to indole butyric acid in plants, but not to indole acetic acid, indicating its role in auxin pathway regulation.

Some patients experience temporary hair loss after ulcerative colitis surgery, likely due to illness rather than the surgery itself, and it usually grows back within six months.

This study found that crossbred lambs fed liquid diets with reconstituted cow's milk initially grew wool without crimp, with crimp resuming two weeks post-weaning.

This review covers dermatological conditions experienced by ice-skating athletes due to cold exposure, infections, and inflammation, providing no new clinical findings and emphasizing diagnosis and treatment strategies.

This article reviews various causes of hair loss linked to systemic factors, noting that careful history and examination can lead to accurate diagnosis, but reports no new clinical results.

In this study, researchers examined androgen receptor activity in the adult mouse brain and found specific expression in key brain areas, which could inform understanding of cognitive side effects in humans undergoing androgen deprivation therapy for prostate cancer.

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 potential cell sources and bioengineering strategies for regenerating hair follicles with functional cycling, reporting no new results.

This paper reviews different types of hair shaft dysplasias and does not report any new clinical findings.

This study found that dietary serine levels influence hair follicle stem cells' ability to balance hair regeneration and wound repair, offering insights for potential interventions to accelerate wound healing.

In this study, the combination of arsenic toxicity and hypoxia in Arabidopsis thaliana altered root development through stress-specific root growth phenotypes and changes in phosphate starvation response, energy metabolism, and redox signaling.

This research reviewed literature to evaluate the role of micronutrients in hair loss and hair growth, examining normal nutrient levels, their role in the hair follicle cycle, and their use in treatments, with data drawn from 92 peer-reviewed articles and reputable health organizations.

This narrative review explores how obesity, related diseases, and bariatric surgery can impact hair health and the hair development cycle, highlighting potential effects such as hair thinning and telogen effluvium.

This study found cell-specific variations in POMC mRNA and peptide expression in murine skin, suggesting that PC1 and PC2 convertases contribute to differential POMC processing.

This study found that cyclophosphamide induced significant keratinocyte apoptosis in anagen hair follicles of mice, while topical calcitriol-analogs reduced this apoptosis, suggesting a protective effect against chemotherapy-induced alopecia.

This article reviews the impact of nutritional deficiencies on hair health, detailing how they can cause structural abnormalities, pigmentation changes, or hair loss; it presents no new clinical findings.

In this study, flutamide at therapeutic doses caused significant histological changes in the testes and epididymis of adult albino rats, reducing androgen receptor immunoreactivity and increasing estrogen receptor immunoreactivity.

This study found that multiple ion channel modulators, used here at clinical concentrations, increased intracellular calcium release in prostate and breast cancer cell lines.

This study found that bovine lactoferrin promotes hair growth in mice by enhancing dermal papilla cell proliferation through the Erk/Akt and Wnt signaling pathways.

This study found that finasteride treatment decreased VEGF expression in the prostate tissue of patients with benign prostatic hyperplasia, although it did not affect vascular density or serum VEGF levels.

This study found that a higher potassium diet in lysine-deficient rats partially protected against hair loss and increased liver fat, suggesting these rats require more potassium.

This review discusses molecular signaling pathways and nutritional factors influencing feather growth and regeneration in poultry and offers no new results; the authors suggest these insights may guide strategies for producing superior plumage.

This study observed that deleting ARNT in keratinocytes of mice reduced zigzag hair production and altered hair follicle differentiation, likely by affecting the expression of specific cyclin-dependent kinase inhibitors.

This review discusses the role of nutrients in hair graying management and finds a possible link between low copper, iron, and vitamin B12 levels and premature hair graying.

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.
