Scientists Uncover Simple Way to Fight Grey Hairs

Say goodbye to hair dye? A new study from Nagoya University in Japan suggests a simple dietary solution for preventing gray hair, and it might already be in your fridge. Researchers have found that the antioxidant luteolin appears to prevent the graying process in mice, offering a potential pathway to similar results in humans.

The study, published in reputable journals, focused on the effects of three antioxidants – luteolin, hesperetin, and diosmetin – on mice bred to develop gray hair. Surprisingly, only luteolin showed a significant effect, preventing the mice’s fur from turning gray, regardless of whether the antioxidant was administered topically or orally. While their cage mates’ fur turned gray, the mice treated with luteolin maintained their original color.

Luteolin is found in several common vegetables, including celery, broccoli, carrots, onions, and peppers. This makes it easily accessible for those looking to incorporate it into their diet. Lead author Professor Masashi Kato called the results surprising, suggesting that luteolin has a unique medicinal effect on preventing graying.

Gray hair is a natural part of aging. As we age, the pigment cells in our hair follicles, responsible for hair color, begin to die. This leads to the growth of unpigmented, gray hairs. While some embrace the silver look, others seek ways to conceal it. This new research offers a potential alternative to hair dye.

The researchers were also surprised to discover that luteolin’s effect wasn’t related to the hair cycle. Instead, it appears to directly impact pigmentation. “Interestingly, luteolin had limited effects on hair cycles, indicating that its primary impact is on pigmentation rather than hair growth or shedding,” explained Professor Kato. “This targeted action makes luteolin a particularly intriguing candidate for addressing age-related hair greying.”

While the study’s findings are promising, it’s important to remember that the research was conducted on mice. However, because the graying process is similar in humans, the researchers are optimistic about the possibility of developing a similar treatment for people.

Beyond its potential for preventing gray hair, the research team is also exploring whether luteolin could play a role in preventing age-related hair loss. Dr. Takumi Kagawa, an author of the study, suggested further research into the antioxidant’s potential for addressing other age-related changes, including balding.

For those who aren’t fans of the vegetables mentioned, luteolin is also available in supplement form for topical or oral use. While further research is needed, this study offers a potentially exciting new approach to combating gray hair and other age-related hair changes.
