This case report concluded that undiagnosed Menkes disease, an X-linked disorder causing copper deficiency, contributed to a 7-month-old's illness and death, complicating his presentation with viral septic shock and methamphetamine exposure.

This study found that males with early onset androgenetic alopecia had significantly lower serum vitamin D levels compared to age-matched healthy controls, although no correlation between the severity of alopecia and vitamin D levels was observed.

This review highlights that while vitamin and mineral supplementation shows limited impact on hair loss treatment, deficiencies in iron, zinc, and vitamin D are common among patients with telogen effluvium.

This review discusses the evidence for biotin supplementation in treating hair loss, concluding that its benefits are poorly supported by data and advising against routine use without more compelling future trials.

This case report describes a 4-year-old girl with Rapunzel syndrome, presenting with severe anemia and a contained perforation, who underwent successful surgical removal of a large gastric trichobezoar.

This case study describes a 34-year-old woman with low serum zinc levels, skin lesions, and hair loss, potentially linked to excessive alcohol consumption.

Eating disorders can cause various hair problems, and while hair loss in these disorders is linked to metabolic syndrome, treatment focuses on specific medications and lifestyle changes for the syndrome.

In this study, researchers reported that individuals from iodine-deficient regions have an increased risk of developing hypothyroidism from MDR-TB treatment regimens containing PAS and/or Prothionamide.

This study found that mutations in the TMPRSS6 gene affect the ability of matriptase-2 to inhibit hepcidin, which may impact the molecular pathogenesis of iron-refractory iron-deficiency anemia.

Hair graying is caused by the loss of pigment cells due to poor maintenance of stem cells in the hair follicle.

This study describes how shotgun proteomics can identify over 300 proteins in hair shafts, potentially allowing for the diagnosis of diseases through noninvasive human proteome sampling.

This article discusses the various cosmetic, medical, and surgical treatment options for androgenetic alopecia but reports no new clinical findings, emphasizing the importance of differential diagnosis in treatment planning.

This review discusses diagnostic strategies for pediatric hair loss, emphasizing the importance of thorough examinations and dermoscopy for accurate diagnosis, and reports no new research findings.

This source discusses premature greying of hair, often linked to lifestyle, stress, and nutritional deficiencies, and notes mainstream dermatology focuses on dietary supplements, while homeopathy offers a holistic approach for treatment.

This source discusses the various causes of premature greying of hair, highlighting lifestyle, genetic factors, and nutritional deficiencies, and contrasts mainstream dermatology's focus on nutritional supplementation with homeopathy's holistic treatment approach for long-term management.

Many new moms lose hair after childbirth due to hormonal changes, but it usually grows back within a year.

This review explores the connection between COVID-19 infection and telogen effluvium, highlighting the potential contribution of inflammatory and emotional factors to hair loss; it reports no clinical results.

This review discusses the relationship between zinc deficiency and skin disorders, emphasizing zinc transporters' roles, but it reports no new clinical results; the authors highlight potential benefits of regulating zinc levels via transporters.

This descriptive study reports that zinc deficiency in two dairy goats likely resulted from hereditary malabsorption, requiring life-long zinc supplementation to prevent skin lesions.

This study found that patients with androgenetic alopecia had deficiencies in certain trace elements and vitamins, which were linked to distinct patterns of hair loss connected to androgen levels.

This article discusses iron deficiency anemia, its health implications, and the effectiveness of oral iron supplements in treatment, but reports no new clinical findings.

This study found that normalizing mineral ion levels in vitamin D receptor-ablated mice prevented hyperparathyroidism, rickets, and osteomalacia, but alopecia persisted, indicating a separate role for the receptor in hair growth.

This paper discusses X-linked ichthyosis and its genetic causes, focusing on biochemical pathways and their role in epidermal differentiation and barrier function, but it presents no new clinical findings.

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

This study details the isolation and characterization of the human type II 5 alpha-reductase gene, which may play a role in male pseudohermaphroditism, prostate cancer, and benign prostatic hyperplasia.

This study found that 38% of women with hair loss had a biotin deficiency, suggesting oral biotin supplementation should be based on confirmed biotin deficiency rather than as a general treatment.

This review discusses genetic and nutritional causes of hair loss, highlighting that around 90% of treated men show noticeable hair regrowth with a dual inhibitor, while women's hair loss may improve by correcting iron and l-lysine deficiencies.

This study suggests that the paradoxical effects of androgens on hair growth are due to differential gene expression in hair follicles, possibly established during embryogenesis.

This study found significantly lower serum vitamin D concentrations in patients with alopecia areata compared to healthy controls, suggesting that vitamin D deficiency may be a risk factor for this autoimmune hair loss disease.

The study found that severe insulin resistance and premature diabetes are common in patients with PCNT genetic defects, primarily affecting those over four years old, while not impacting early insulin signaling in adipocytes.
