Blueberries
Blueberries are rich in anthocyanin and vitamin C, two nutrients that have a strong effect in fighting free radicals, which damage hair follicle cells and reduce melanin pigmentation.
A diet rich in antioxidants helps slow down the aging process of hair and reduce the rate of premature graying.
Blueberries are not only good for the heart but also help nourish hair follicles from within. Vitamin C supplementation also helps the body absorb iron more effectively, a mineral necessary for healthy hair growth.
A glass of blueberry smoothie in the morning or eaten with unsweetened yogurt is a simple way to maintain natural hair color.
Walnuts
Copper is an important mineral in the production of melanin - the pigment that determines hair color. Walnuts are one of the most common nuts, and also provide omega-3 fatty acids that help improve blood circulation to nourish the scalp.
According to the National Institutes of Health (NIH, USA), only 28g of walnuts can provide up to 0.45mg, meeting about 50% of daily needs.
Omega-3 in walnuts also helps reduce inflammation and supports healthy hair follicles.
A diet lacking in copper may be associated with premature gray hair. Walnuts provide copper and many other nutrients, both protecting hair color and improving hair texture.
Adults can eat a small handful of walnuts per day, eat directly or mix them with salads and cereals.
Black grape
Black grapes are not only sweet but also contain high levels of polyphenols, resveratrol and iron. These compounds help protect hair follicle cells, while stimulating the formation of red blood cells, ensuring blood continuously nourishes hair.
Resveratrol in grapes has the ability to slow down cell aging, thereby maintaining natural hair color longer.
A diet rich in polyphenols from fruits such as black grapes helps reduce the effects of oxidative stress, which is the main factor that causes premature gray hair.
In addition to eating fresh, black grapes can be juiced or made into a healthy dessert, both supplementing iron and enhancing antioxidants.
