Recent studies have highlighted luteolin, a plant compound found predominantly in various vegetables, as a potential agent in delaying hair graying. While research focused on mice indicates positive results, experts urge caution before drawing conclusions regarding its effects on humans.
Luteolin is a polyphenol abundant in foods such as celery, green peppers, broccoli, and carrots. Registered dietitian Toby Amidor, MS, RD, CDN, notes its significance by stating, “Luteolin is a polyphenol, which is a plant compound that may have health benefits and is found in foods like celery, green pepper, broccoli, carrots, and olive oil.” However, many individuals in the United States struggle to meet their recommended daily vegetable intake. In fact, only one in ten Americans consumes the suggested amount of vegetables, making luteolin a common dietary supplement.
The antioxidant properties of luteolin are noteworthy. It has been shown to protect against skin aging and inflammation while also modulating these processes. Moreover, preliminary findings suggest that luteolin can safeguard human retinal pigment epithelial cells from oxidative stress-induced cell death and regulate inflammation in various cell types. This raises intriguing possibilities for its broader applications in health management.
In animal studies, specifically involving mice, luteolin has exhibited a remarkable effect on hair pigmentation. Mice treated with luteolin retained significantly more dark fur compared to those treated with alternative antioxidants. This suggests that luteolin could potentially influence the graying process, although genetics are likely the dominant factor determining when and how much hair turns gray.
Experts emphasize the need for further research to understand the full implications of luteolin for hair health. Collins notes the caution required when considering luteolin supplementation, stating, “Some individuals may experience gastrointestinal discomfort or allergic reactions.” He further advises that “as with any supplement, it’s best to consult a healthcare provider before adding it to a routine.”
The potential therapeutic benefits of luteolin extend beyond hair health. It has been recognized as a promising natural agent in managing pain associated with chronic conditions. However, until clinical trials are conducted on humans, definitive statements regarding its effectiveness for graying hair remain speculative. Collins emphasizes this point: “Until clinical trials are conducted on humans, it’s too soon to say whether luteolin could be a viable solution for graying hair.”
Despite the excitement surrounding luteolin, experts recommend maintaining a balanced diet rich in antioxidants and managing stress through mindfulness or exercise as viable methods to potentially slow down hair graying. Amidor echoes this sentiment by highlighting the importance of dietary sources: “There are numerous food sources of luteolin, including celery, green pepper, broccoli, carrots, olive oil, thyme, beets, Brussels sprouts, cabbage, cauliflower, chili peppers, lettuce, and spinach.” She adds that “as luteolin is found primarily in vegetables—and only one in ten people in the U.S. get their recommended daily amount of veggies—it is just another reason to eat more vegetables.”
The side effects of luteolin supplementation should not be overlooked. Collins warns that gastrointestinal discomfort or allergic reactions may occur in some individuals. Furthermore, Amidor advises caution regarding the lack of comprehensive studies: “I would wait for the science before blindly taking a supplement that is not truly backed up by the research—especially the dosage, length of time to take it, toxicity effects, and any medication interactions, which are all unknown at this time.”
