Substance in broccoli, celery inhibits graying of black hair

NAGOYA--A natural compound in celery, broccoli and other plants inhibits black hair from going gray, research shows.

Machiko Iida, a specially appointed assistant professor of occupational and environmental health at Nagoya University’s Graduate School of Medicine, said she and her colleagues discovered via an experiment with mice that luteolin, a flavonoid variant, alleviates graying of hair. Masashi Kato, professor of medicine at Nagoya University, said in a statement that the research will likely lead to the development of a topical agent and an oral dietary supplement utilizing luteolin “that provides a novel option to hinder hair from graying.” The ability of luteolin to promote skin health through antioxidative and anti-aging mechanisms was already known, but this was the first time its effectiveness in inhibiting the graying of black hair has been scientifically verified.
