,
February 2009 in “The FASEB Journal” This study found that hydrogen peroxide accumulation and reduced methionine sulfoxide repair play a significant role in the oxidative damage linked to senile hair graying.
June 2025 in “Cell Regeneration” In this study, Dguok deficiency in mice led to premature hair greying due to a loss of melanocyte stem cells and mature melanocytes, with increased oxidative stress and cell death; treatment with an antioxidant mitigated these effects, suggesting DGUOK's importance in hair pigmentation maintenance.

May 2006 in “The FASEB journal” This study found that oxidative stress in hair follicle melanocytes contributes to premature aging and apoptosis, providing insights into graying as a model for studying aging and testing antiaging therapies.
December 2024 in “Antioxidants” This study found that external and internal luteolin treatments reduced hair graying in model mice by mitigating age-related dysfunction in hair stem cell signaling, suggesting potential practical applications for anti-graying treatment in humans.
