The 7 Best Vitamins & Minerals for Hair Growth

Many people view healthy-looking hair as a sign of health or beauty. Like any other part of your body, hair needs a variety of nutrients to be healthy and grow.

In fact, many nutritional deficiencies are linked to hair loss.

While factors such as age, genetics and hormones also affect hair growth, optimal nutrient intake is key. Below are 7 vitamins and minerals that are important for hair growth.

Vitamin A

All cells need vitamin A for growth. This includes hair, the fastest growing tissue in the human body.

Vitamin A also helps skin glands make an oily substance called sebum. Sebum moisturizes the scalp and helps keep hair healthy.

Diets deficient in vitamin A may lead to several problems, including hair loss.

While it’s important to get enough vitamin A, you don’t want too much. Studies show that too much vitamin A can also contribute to hair loss.

Sweet potatoes, carrots, pumpkins, spinach, and kale are all high in beta-carotene, which is turned into vitamin A.

Vitamin A can also be found in animal products such as milk, eggs, and yogurt. Cod liver oil is a particularly good source.

B Vitamins

One of the best-known vitamins for hair growth is a B vitamin called biotin. Studies link biotin deficiency with hair loss in humans.

Although biotin is used as an alternative hair loss treatment, those who are deficient have the best results. However, deficiency is very rare because it occurs naturally in a wide range of foods. There’s also a lack of data about whether biotin is effective for hair growth in healthy individuals.

Other B vitamins help create red blood cells, which carry oxygen and nutrients to the scalp and hair follicles. These processes are important for hair growth.

You can get B vitamins from many foods, including whole grains, almonds, meat, fish, seafood, and dark, leafy greens.

Additionally, animal foods are the only good sources of vitamin B12. So, if you’re following a vegetarian or vegan diet, consider taking a supplement.

Vitamin C

Free radical damage can block growth and cause your hair to age. Vitamin C is a powerful antioxidant that helps protect against the oxidative stress caused by free radicals.

In addition, your body needs vitamin C to create a protein known as collagen — an important part of hair structure.

Vitamin C also helps your body absorb iron, a mineral necessary for hair growth.

Strawberries, peppers, guavas, and citrus fruits are all good sources of vitamin C.

Vitamin D

Low levels of vitamin D are linked to alopecia, a technical term for hair loss.

Vitamin D is thought to play a role in hair production, but most research focuses on vitamin D receptors. The actual role of vitamin D in hair growth is unknown.

Most people don’t get enough vitamin D, so it may be a good idea to increase your intake.

Your body produces vitamin D through direct contact with the sun’s rays. Good dietary sources of vitamin D include fatty fish, cod liver oil, some mushrooms and fortified foods.

Vitamin E

Similar to vitamin C, vitamin E is an antioxidant that can help prevent oxidative stress.

In one study, people with hair loss experienced a 34.5% increase in hair growth after supplementing with vitamin E for 8 months.

The placebo group had only a 0.1% increase.

Sunflower seeds, almonds, spinach, and avocados are all good sources of vitamin E.

Iron

Iron helps red blood cells carry oxygen to your cells. This makes it an important mineral for many bodily functions, including hair growth.

Iron deficiency, which causes anaemia, is a major cause of hair loss. It’s especially common in women.

Foods high in high include clams, oysters, eggs, red meat, spinach, and lentils.

Zinc

Zinc plays an important role in hair tissue growth and repair. It also helps keep the oil glands around the follicles working properly.

Hair loss is a common symptom of zinc deficiency. Studies show resolving zinc deficiency with supplementation may reduce deficiency-related hair loss.

However, there are some anecdotal reports that supplementing with too high of a dose can also contribute to hair loss.

Foods high in zinc include oysters, beef, spinach, wheat germ, pumpkin seeds, and lentils.

So, just to conclude food is the best source of the vitamins you need for hair growth. However, if you fail to get enough in your diet, supplements may be helpful.
