Like other body organs, the hair also needs a variety of nutrients to remain healthy and grow. As a matter of fact, hair loss is related to the lack of many nutrients. Other factors like age, genetics, and hormones are also effective on hair growth, however, optimized consumption of nutrients can be considered an efficient solution to prevent this issue.
In the following, we are going to point out 5 vital vitamins in hair growth.

Vitamin C:
Damages resulting from free radicals on the hair can cease hair growth. Vitamin C is a strong antioxidant that protects the hair against the free radicals' oxidative stresses. Vitamin C is also needed for the body to produce collagen which is the main component of the hair structure. This vitamin helps absorb iron which is an essential mineral for hair growth. Strawberries, peppers, and lemons are good resources for Vitamin C.

Vitamin D:
The reduction in the level of Vitamin D is one of the main reasons for hair loss. Vitamin D plays an important role in hair structure. Your body absorbs Vitamin D from sun rays. Among food resources, we can point out fish and some types of Mushrooms.

Vitamin B:
One of the most recognized B Vitamins is Biotin. Studies show that the lack of Biotin causes hair loss. As a matter of fact, Vitamin B helps the production of red globules and enhances nutrition and oxygenation to the scalp; however, it is so rare that the body faces a lack of this vitamin because it can be found in a variety of foods.

Vitamin E:
Similar to Vitamin C, Vitamin E is another antioxidant that prevents Oxidative stress. One study showed that over an 8 month period, 34.5% of the people suffering from hair loss had an increase in their hair growth after taking Vitamin E supplements. Among the major resources for Vitamin E, sunflower seeds, almonds, and spinach are more recognized.

Vitamin A:
All body cells, including hair cells, need Vitamin A to grow. Vitamin A also helps the Sebaceous gland produce Sebum. The produced sebum preserves the scalp moisture and keeps the hair healthy. Diets causing the lack of vitamin A create so many problems, including hair loss. It must be bear in mind that the increase in the Vitamin A amount also causes hair loss. Therefore you should be careful about the appropriate consumption amount of this substance.
