*Biotin
It is the most essential vitamin for Healthy Hair. Every supplement or vitamin that claims to be for hair growth or strength has a large amount of Biotin in it. It is found in meat, saltwater fish, egg yolks, milk, poultry, grains and yeast. Biotin is also an important part of your metabolism and energy production, so it is important to get enough of this vitamin
*Vitamin E
Vitamin E increases the circulation to the scalp; it also helps in hair growth and even reverse hair loss, to a point. Vitamin E is usually known for helping your skin be healthy and stretchy . It can also help prevent stretch marks or lessen the effects of aging.
*Vitamin A
Because Vitamin A is essential for a healthy immune system, it also helps with healthier nails and hair. If your immune system is working properly, you will have a healthier body and each system will work to the best of their function. If you look at all those gimmicky hair growth pills, you will see a large percentage of Vitamin A in all of them
*Vitamin C
Also helps with blood circulation, therefore helps with the scalp and follicles which can speed up the hair growth. You can take a Vitamin C supplement, or eat a lot of oranges, berries or leafy greens
*Zinc
This is another vitamin that really helps with the overall health of your hair. Heavy exercisers or sweaters tend to lose great amounts of zinc, so if you fit into that category you may want to consider taking some zinc supplements
*Iron
Even though this isn’t a vitamin, it’s a mineral that is really important to help your body function correctly…this includes helping with healthy hair!
