A handful of walnuts a day is beneficial for healthy hair. Walnuts may prevent hair loss. They’re particularly high in biotin and other important nutrients for hair growth.
How much biotin is in walnuts?
According to a study, published in The Journal of Clinical and Aesthetic Dermatology, biotin can safely and effectively promote significant hair growth in women with temporary hair thinning.
The recommended daily intake of biotin is 30 mcg. Just a handful of walnuts (7 walnuts) contains about 0.7 mcg of biotin. This amount is 2.3% of the Daily Value. You can eat 14 walnuts to get almost 5% of the DV.
Healthy people who follow a well-balanced diet are rather unlikely to be deficient in biotin.
You can find a wide variety of biotin supplements on iHerb.
Omega-3s in walnuts are essential for healthy hair
Walnuts are rich in omega 3 fatty acids. Omega-3s may help grow healthy and strong hair. Actually, they’re vital for preventing hair loss and improving hair density.
Consuming walnuts regularly is a great way to boost your daily omega-3 intake. Walnuts are among the richest foods in omega-3s. Actually, there are only a few foods high in omega-3s. A handful of walnuts contains more omega-3s than the recommended daily intake!
Vitamin E in walnuts for hair growth
Eating foods high in vitamin E is beneficial for healthy hair. Vitamin E is a powerful antioxidant. It neutralizes free radicals and fights oxidative stress, which can cause hair loss.
We need about 15 mg of vitamin E a day. Most common walnut varieties provide between 0.9 mg and 2.1 mg of vitamin E per 100g. A handful provides up to 0.6 mg of vitamin E, or 4% of the DV.
Moreover, you should eat sunflower seeds, almonds, and hazelnuts. They’re the richest foods in vitamin E.
Selenium in walnuts for hair loss
Another vital nutrient for preventing hair loss is selenium. Selenium has potent antioxidant action, and it’s essential for healthy hair, which grows fast. Low levels of selenium may negatively affect the health of hair follicles. Walnuts are a great source of dietary selenium. A handful provides 9% of the DV.
Walnuts may relieve stress
Besides nutritional deficiencies, infections, as well as emotional and physiological stress are common causes of hair loss and hair thinning.
Emotional stress can cause hair loss. Strong hair depends on healthy hair follicles. Stress can interfere with the ability of the tissue to be regenerated, causing hair loss.
How many walnuts to eat per day for hair growth?
You can eat 1-2 handfuls of walnuts a day to boost your daily intake of biotin, vitamin E, omega-3s, selenium, and other antioxidant compounds, which protect hair follicles and promote hair regrowth.
Avoid eating higher amounts, though. Walnuts are high in calories. So, too many walnuts can make you gain weight.
Walnut oil protects your hair from infections
In addition, you could apply walnut oil directly to your hair. Walnut oil prevents infections, due to its powerful antimicrobial and antibacterial properties.
Furthermore, walnut oil hydrates, strengthen and thickens the hair. Massage the hair gently to nourish it. Moreover, people use it as a home remedy for dealing with dandruff, preventing growing of gray hair.
