Your body is a machine that works relentlessly. To ensure everything runs smoothly, every part of your body works in synchronicity with other components. Your body needs a balanced diet that includes proteins and carbs. Similarly, the human body needs essential vitamins. Vitamins perform many vital functions in the human body. 

Here are five vitamins you need to be taking if you want longer hair. 

Vitamin A

All cells need vitamin A for the body for growth. Vitamin A is crucial for helping your hair follicles do their job. It enables the skin to generate sebum which keeps your scalp moisturized. A moisturized scalp means no dandruff. A diet low in Vitamin A would suggest that you suffer from an itchy scalp. Lack of Vitamin A can also result in hair loss. Some foods rich in Vitamin A are dairy products, fish, carrots, and liver.

Vitamin C

Vitamin C is known for its antioxidant properties. It is suitable for your body, especially when you're down with a cold. Vitamin C is also ideal for fighting radicals that cause brittle hair. Vitamin C also helps your body absorb iron which is integral for promoting hair growth. Some foods rich in Vitamin C are red and green peppers, strawberries, Brussel sprouts, and various other foods.

Vitamin D

You've probably heard it a lot in your life. You need vitamin D for your bones. People recommend soaking in sunlight for fifteen minutes every day to create the required dose of vitamin D. A hair loss condition called alopecia is linked with low Vitamin D levels. Vitamin D helps promote hair growth by strengthening hair follicles. Other sources of Vitamin D include eggs, mushrooms, salmon, sod liver oil, and milk. 

Vitamin E

Vitamin E is an antioxidant that can prevent free radical damage and protect the body's cells. Vitamin E helps maintain a healthy immune system. In hair, vitamin E helps prevent frizz by turning damaged and unmanageable hair into silky tresses. Vitamin E helps prevent hair loss, aids in oil production in the scalp, and adds shine to hair. Nuts, leafy greens, sunflower oil, and olive oil are sources of Vitamin E. 

Vitamin H or Vitamin B7 aka Biotin 

Vitamin H or Vitamin B7 are some names of a compound we more commonly know of as Biotin. Vitamin H is a part of the Vitamin B family and is water-soluble. Keratin is the protein that makes your skin, nails, and hair structure. Biotin promotes hair growth and is an ingredient in many hair care products. Foods rich in Biotin include bananas, mushrooms, cauliflower, organ meats such as kidney and liver, among other things. 

There are many ways you can take vitamins. You can take them in the natural form they come in, i.e., food, or you can take supplements. 

Many hair care products include these vitamins, so using them (with due diligence) can also be beneficial.
