For preventing grey hair, focus on Vitamin B12-rich animal products like beef liver, clams, salmon, eggs, and dairy, plus fortified cereals, as B12 deficiency hinders melanin production, while also adding iron (leafy greens), copper (nuts, shellfish), and antioxidants (berries, dark chocolate) for overall hair pigment health.
Q: Can Vitamin B12 prevent gray hair? A: While there is no conclusive evidence that Vitamin B12 can reverse grey hair, it may help prevent premature greying by supporting overall hair health. Adequate levels of Vitamin B12 contribute to healthy hair growth and may help maintain hair color.
Additional Tips for Managing Hair Greying
Sometimes, melanocytes - the pigment-producing cells in hair follicles may start functioning again, leading to darker hair regrowth. This is rare, but not unheard of in people recovering from hormonal shifts, an illness or medication adjustments. The other possible cause is your medication.
Low B12 allows folate levels to rise, which has been linked to hair loss. Research indicates that correcting a vitamin B12 deficiency can help treat hair loss and stimulate growth. However, the condition may become irreversible if prolonged deficiency causes permanent follicle damage.
A review of research suggests that proper supplementation may reverse premature graying in those who are deficient in certain nutrients, including iron, vitamin D, and vitamin B12. However, even though some supplements are specifically sold as “anti-graying,” there aren't any studies that prove they work.
Vitamin B12 deficiency symptoms develop gradually and include extreme fatigue, pale skin, shortness of breath, headaches, and nerve issues like numbness or tingling in hands/feet, plus cognitive problems such as memory loss and confusion, often linked to anemia but also affecting nerves and brain function, requiring medical diagnosis and treatment.
Vitamin A, C and B12 are the most needed vitamins to increase the melanin production in your hair. Add citrus fruits like oranges, grapes, pineapple, and melon to your diet. Also eat vegetables like potatoes, carrots, beans, etc. Non vegetarians can try adding red meat, chicken liver, fish, and eggs to their diet.
15 Home Remedies for Grey Hair
Korean grey hair treatments focus on nourishing the scalp, using natural ingredients like ginseng to boost melanin (like WT Methode or Daeng Gi Meo Ri) for potential color restoration, or employing pigmented shampoos (like Moda Moda or Ryo) for temporary darkening, often avoiding harsh chemicals for gentle coverage, alongside general hair health via oils, serums, and toning. While no magic cure reverses all gray, these K-beauty approaches manage premature graying and maintain color naturally.
Prevent Premature Graying
A vitamin B12 deficiency is one of the major contributing factors to premature hair graying. Why? B vitamins can inhibit hair from losing its pigment. And since blueberries are an excellent source of B12, your hair may maintain its natural color even longer if you eat them regularly.
While Vitamin B12 is generally safe, potential disadvantages (side effects) can occur, especially with high doses or injections, including headaches, nausea, diarrhea, weakness, skin issues (rash, itching), and rarely, more serious heart or allergic reactions (like anaphylaxis), though toxicity from oral intake is rare as excess is usually excreted. Conversely, a deficiency can cause serious problems like irreversible nerve damage, memory loss, fatigue, infertility, and increased risk of certain cancers, making proper intake crucial.
Premature graying may be reversed with vitamin B12 supplementation only if vitamin B12 deficiency is the cause. If you are graying due to other factors, such as genetics, zinc deficiency, and medications, your gray hair cannot be reversed.
Vitamin B12 is abundant in animal products like meat (especially liver), fish (salmon, tuna, sardines), poultry, eggs, and dairy (milk, yogurt, cheese), with fortified foods such as cereals, nutritional yeast, and plant milks offering options for vegetarians and vegans, as plants don't naturally contain B12.
B12 deficiency can trigger specific food cravings, most notably for meat, fish, or eggs, as the body seeks animal-based sources to replenish the vitamin, especially in those on vegetarian/vegan diets or older adults. While cravings for sugary or salty foods can also signal general B-vitamin issues, the distinct urge for protein-rich animal products is a key indicator, but professional testing is crucial for confirmation.
To quickly increase B12, focus on animal products (meat, fish, dairy, eggs) and fortified foods (cereals, plant milks, nutritional yeast), but for a significant deficiency or rapid boost, especially if dietary changes aren't enough, consult a doctor for high-dose supplements or B12 injections, as severe cases require medical intervention for proper absorption and treatment, note NHS and Healthline.
Causes of Vitamin B12 deficiency
Vitamin deficiencies such as low iron, copper, b12, and hypothyroidism can lead to premature greying. Compelling evidence suggests that prolonged intense stress can cause premature greying. Oxidative stress from the sun and tanning damages the pigment cells of the hair root causing hairs to become grey.
Taking too much vitamin D leads to calcium buildup (hypercalcemia), causing physical signs like nausea/vomiting, fatigue/weakness, frequent urination & excessive thirst, constipation, and confusion/disorientation, alongside potential bone pain or kidney stones, often from supplements, not sun exposure.
Curlzvit Tablet is a dietary supplement for premature greying and hair fall. It supplies hair with fortifying substances like biotin, PABA, inositol and calcium pantothenate. It maintains the hair structure, strengthens hair, and increases the resistance of hair to mechanical and chemical damage.
Symptoms of vitamin B12 or folate deficiency anaemia
Vitamin H is known to stimulate hair growth. Studies have shown that biotin deficiency can lead to hair loss. While biotin can be used to treat hair loss, the best results occur in individuals who are biotin deficient. However, biotin deficiency is quite rare as it is found in many food sources.
Taking vitamin B12 daily is generally safe for most people, as it's water-soluble and excess is flushed out, but high doses can cause mild side effects like headaches, nausea, dizziness, or diarrhea in some individuals, while very high levels (especially from injections) might rarely link to other issues, so it's best to stick to recommended amounts unless treating a diagnosed deficiency.
