Which vitamins are good for hair growth?

Vitamins do a lot of amazing things for hair: They can help cell growth, prevent free radicals from damaging it, stop it from graying prematurely, and nourish growth-stimulating follicles.

Here are the best vitamins for hair growth and thickness.


Biotin, also known as vitamin B7, stimulates keratin production to increase follicle growth. Biotin deficiencies tend to be rare, with those diagnosed with biotinidase deficiency being the most common. You can find this vitamin in many foods, including eggs, meat, fish, nuts, eggs, sweet potatoes, and seeds.

The recommended intake is 30 micrograms for adults per day.

Vitamin A

Hair cells are the fastest growing party from the body. It is logical, then, that vitamin A is the perfect fuel for this growth. When your body absorbs vitamin A, it produces sebum. It is an oily substance that hydrates your scalp, keeping it and your hair follicles healthy. Vitamin A deficiency can lead to hair loss.

If you are looking to consume more vitamin A, you will want to consume foods high in beta-carotene, which converts into vitamin A. Foods high in beta-carotene include sweet potatoes, pumpkin, carrots, spinach, and kale. You can also find it in cod liver oil, eggs, yogurt, and milk.

The recommended daily intake of vitamin A is up to 900 mcg for men and 700 mcg for women.

Vitamin C

Oxidative stress is one of the major contributing factors to hair loss. It happens when we have an imbalance of free radicals and antioxidants in our body, which can lead to an electronic imbalance that can lead to hair loss.

The solution is to eat foods with vitamin C. Your body has antioxidants that reduce free radical damage to hair by balancing their electrons when you do. In addition to balancing the scales, vitamin C helps your body to produce collagen (prevents hair from graying prematurely) and iron absorbing which can help hair growth. Smoking, drinking alcohol and having a bad diet can lead to vitamin C deficiency.

You will find vitamin C in citrus fruits, peppers, strawberries, tomatoes and guavas. Since your the body does not produce ityou will need to include them in your diet or take a vitamin C supplement.

Daily intake of vitamin C is up to 90 milligrams per day for adult men and 75 milligrams for adult women. Socket too much vitamin C could lead to heartburn, muscle cramps, fatigue, flushing of the skin and possibly kidney stones.

To get more vitamin D, you can incorporate fatty fish, cod liver oil, fortified foods (cereals, eggs, bread, yogurt) and mushrooms into your diet. Alternatively, you can catch a few midday sun rays.

600 IU of vitamin D is the recommended dose for adults. Socket too much vitamin D could lead to nausea, weight loss, disorientation and heart rhythm problems.

Vitamin E

Vitamin E contains the same antioxidant prowess as its vitamin C counterpart. This means it can curb oxidative stress by balancing the level of electrons in free radicals. People most susceptible to vitamin E deficiencies include those with health conditions such as Crohn’s or cystic fibrosis.

Vitamin E is an effective method to treat hair loss. A small study found that people taking vitamin E supplements for eight months experienced a 34.5% increase in hair growth. You can also find vitamin E in sunflower seeds, spinach, avocados and almonds.
