This study presents a method using liquid chromatography tandem mass spectrometry to quantify biotin in plasma and serum, and explores how high biotin intake can interfere with diagnostic immunoassays that utilize biotin-streptavidin technology, potentially leading to misdiagnosis of endocrine disorders.

This case report describes a girl with Denys-Drash syndrome misdiagnosed with hyperandrogenism due to biotin interference in immunoassays, highlighting the need for awareness of laboratory result discrepancies.

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

This case report describes a 10-month-old boy with dermatitis, alopecia, and hypotonia who showed dramatic improvement with oral biotin, suggesting a possible defect in biotin absorption or transport.

In this study, the researchers observed that biotin administration in biotin-deficient children with alopecia eliminated certain membrane proteins from their blood, suggesting that biotin might regulate these proteins' expression.

This study found that germ-free mice on a biotin-deficient diet exhibited significant weight loss and severe alopecia, unlike conventional mice on the same diet.

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.

Researchers created a reliable method to measure dexpanthenol and resorcinol in hair products.

This study observed that smokers and alcohol consumers with androgenetic alopecia had significantly lower serum levels of antioxidant vitamins, and these habits may trigger earlier onset of alopecia in susceptible individuals.

This study demonstrates that keratinocyte cell lines derived from cultured hair follicles can fully differentiate in organotypic skin models, offering a minimally invasive alternative to obtaining keratinocytes for research.

This review highlights the increasing use of herbal cosmetics for maintaining healthy hair growth and preventing premature greying, influenced by rising living standards and interest in personal care.

Some nutrients and antioxidants may improve skin and hair health, but more research is needed to confirm these benefits.

This review discusses biotin and biotinidase deficiencies, their symptoms, and methods of medical management, without presenting new clinical findings.

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 study found that human keratinocytes express a sodium-dependent multivitamin transporter for biotin, pantothenic acid, and lipoic acid, including a highly specific biotin transport component.

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

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.

This review summarizes causes and treatments of androgenetic alopecia with a focus on herbs as potential alternatives, but reports no new results and suggests more research is needed to validate these options.

This article explores how various nutrients and metabolic processes impact wool and hair follicle function in animals but reports no new experimental findings.

This review discusses studies on hair growth and protein synthesis in hair follicles, highlighting the differing responses of mohair and cashmere goat follicles to signaling molecules, biotin, and amino acids, but contains no new results.

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.

AGA is a genetic, hormonal hair loss treated with finasteride, minoxidil, and supplements, but new compounds are being developed.

In this animal study, applying a combination of inositol-stabilized arginine silicate complex and magnesium biotinate promoted hair growth but not nail growth.

This study found a significant decline in serum zinc levels among women of African descent using hair relaxers and experiencing alopecia, with age at first exposure potentially influencing alopecia development.

This study identified that biotin ingestion led to interference in immunoassay results, falsely indicating high testosterone and insulin levels in a 28-year-old female patient, thus complicating her clinical assessment and treatment planning until recognized and resolved.

This study reports a case of Indralupta (Alopecia Areata) successfully treated using Ayurvedic methods including Prachhan karma, Lepa, and Shirodhara, offering an alternative to conventional treatments like minoxidil and steroids, which may have adverse effects.

This article provides a clinical Q&A on bariatric nursing and surgical patient care and reports no new research findings.

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 reports that a low concentration of chitosan induces callose deposition and slows root hair growth in Arabidopsis, suggesting an evolutionary conservation of this response to mild biotic stress across plant types.
