This case report highlights that a patient with resistance to thyroid hormone was misdiagnosed as having Graves’ disease, leading to unnecessary radioactive iodine treatment.

COVID-19 might cause gray hair to regain color.

This study identified the Hairless (Hr) gene-encoded protein as a corepressor that plays a crucial role in maintaining skin and hair by regulating epithelial stem cell differentiation and gene expression via chromatin remodeling, which may impact both development and disease.

This review explores the causes and management of premature greying in children, noting it may indicate underlying health issues, and emphasizes structured evaluations and treatments, particularly for nutritional deficiencies and hypothyroidism, to address hair depigmentation.

This review highlights concerns around premature greying in children, detailing possible links to nutritional deficiencies and other health issues, and emphasizes that structured evaluation and targeted treatment may aid in reversing the condition.

This study found that Heated radish extract potently suppressed melanin production in vitro and reduced wrinkle formation and collagen degradation in vivo, suggesting its potential as a skin whitening and antiaging product.

Premature graying of hair is mainly caused by genetics, stress, and environment, with potential treatments being explored.
