Melanin is a natural pigment that determines hair colour. When the body's production of this pigment slows down, hair turns grey or white. While greying is a natural part of the ageing process, it can be distressing for some people. Fortunately, there are ways to slow down and even reverse greying hair. This includes making changes to your diet, such as increasing your intake of certain vitamins and minerals, as well as managing your stress levels and reducing exposure to harmful chemicals.

What You'll Learn
Vitamins A, C, and E
Melanin is a natural pigment that determines the colour of hair. When the production of this pigment slows down, hair turns grey or white. While there is no proven link between vitamins A, C, and E and melanin production, these vitamins are important for skin and hair health and may help reduce the risk of skin cancer.
Vitamin A, also known as beta-carotene, is found in dairy, liver, fish, eggs, and many soft fruits, including apricots, nectarines, and peaches. Orange-coloured vegetables like carrots, squash, pumpkin, and sweet potatoes are also healthy sources of vitamin A. Vitamin A is important to melanin production and is essential to having healthy skin. Since vitamin A also functions as an antioxidant, some researchers believe this vitamin may be the key to melanin production.
Vitamin C, also known as ascorbic acid, is used as a treatment modality in the depigmentation of hyperpigmented spots on the skin and gingiva. It is needed for healthy mucous membranes and may have some impact on melanin production and skin protection. Eating vitamin C-rich foods like citrus, berries, and leafy green vegetables may optimize melanin production.
Vitamin E is an important vitamin for skin health and is also an antioxidant. It could possibly boost melanin levels and protect the skin against sun damage. Vitamin E-rich foods include vegetables, grains, seeds, and nuts.
While there are no studies proving a direct link between any of these vitamins and increased melanin production, eating a healthy diet with all food groups, especially iron, proteins, vitamins, and minerals, can help increase melanin in hair.

Vitamins B6 and B12
Melanin is a natural pigment that determines hair colour. When the production of this pigment slows down, hair turns grey or white. As we age, our bodies produce less melanin, leading to a loss of hair colour. This process can be accelerated by factors such as stress, hormonal imbalance, and the use of chemicals. While grey hair is a natural part of ageing, many people seek ways to boost melanin production and restore their original hair colour.
Vitamin B12 deficiency can lead to hair loss and premature greying. This deficiency can be common in vegetarians or vegans, as vitamin B12 is naturally present in foods of animal origin, such as meat, eggs, and dairy. However, it is important to note that simply increasing one's intake of these vitamins may not be enough to decrease grey hair. Grey hair can be caused by a variety of factors, including genetics, and boosting melanin production may not always reverse grey hair.
While there is limited scientific research on the effectiveness of melanin supplements, some sources suggest that certain vitamins and minerals can help slow and even reverse grey hair. In addition to vitamins B6 and B12, vitamins A, C, and E have been found to increase melanin production and improve hair, skin, and nails. A healthy diet that includes all food groups, especially iron, proteins, vitamins, and minerals, can help increase melanin production and delay premature greying.

Antioxidants
Melanin is a natural pigment that determines hair colour. As melanin production slows, hair greying begins. While greying is a natural part of the ageing process, it can also be caused by factors such as stress, nutrient deficiencies, genetics, and lifestyle choices like smoking.
Although there is currently no proven method to reverse hair greying, certain dietary changes can help to slow it down. A diet rich in antioxidants can help to reduce free-radical damage to the body and hair, thereby protecting melanin in hair cells. Antioxidants can be found in foods such as:
- Dairy, liver, fish, eggs, apricots, nectarines, peaches, carrots, squash, pumpkin, and sweet potatoes (Vitamin A)
- Citrus fruits, tomatoes, tomato juice, and potatoes (Vitamin C)
- Dark chocolate, beans, leafy green vegetables, broccoli, carrots, and pumpkin (also a source of biotin, which is associated with hair growth and premature greying)
- Beetroot, sprouts, eggs, fish, cheese, soy, and starchy vegetables (Vitamins B6 and B12)
Additionally, copper plays a role in melanin production and can be found in nuts, mushrooms, and liver.

Copper
There are a variety of copper-rich foods that can be incorporated into the diet to boost melanin production. These include nuts, such as almonds and peanuts, dark chocolate, mushrooms, and liver. In addition to these, hair-growth supplements often contain copper and can be taken to increase copper intake.
While increasing copper intake can help boost melanin production, it is important to note that there are other factors that contribute to grey hair. These include stress, pollution, use of chemicals, and genetics. Additionally, a vitamin B12 deficiency is one of the most common causes of premature greying, and vitamin B6 and B12 have both been proven to boost melanin in hair follicles. Therefore, a holistic approach that addresses diet, lifestyle, and stress management is recommended to effectively decrease grey hair.

Iron
In the context of Parkinson's disease, the interaction between iron and neuromelanin, a form of melanin found in the brain, has been implicated in the neurodegeneration of melanin-containing dopaminergic neurons. This interaction may provide a potential explanation for the vulnerability of these neurons to degeneration in Parkinson's disease.
Additionally, iron-melanin interactions have been studied in relation to other diseases, such as Alzheimer's disease and multiple system atrophy. While the specific mechanisms are still being elucidated, these interactions highlight the complex relationship between iron and melanin in the body.
While the direct link between dietary iron intake and melanin production in hair is not explicitly mentioned in the sources, maintaining a healthy diet that includes all food groups, especially iron, proteins, vitamins, and minerals, is recommended to increase melanin production and promote overall hair health.

Frequently asked questions
Melanin is a natural pigment that determines the colour of your hair. The more melanin, the darker the hair colour and vice versa. As you age, the pigment cells that produce melanin decrease, leading to a loss of melanin and hair greying.
Vitamins B6 and B12 have been proven to boost melanin production. Vitamin B6 triggers the production of enzymes and chemical reactions that boost the metabolism of hair proteins (keratin and melanin) in the hair follicles. Vitamin B12 promotes healthy hair growth by increasing red blood cell production. You can also add foods rich in antioxidants to your diet, such as dark chocolate, beans, leafy green vegetables, broccoli, carrots, and pumpkin.
While there is no conclusive scientific research, boosting melanin through diet and supplements may help slow down and even reverse grey hair. However, if your hair is turning grey due to genetics, it is impossible to restore its original colour through melanin production.
