Though vitamins are often good for the body in general, some specialize in improving certain areas. For example, there are several vitamins for hair growth, with vitamin E being one of them due to its ability to improve blood circulation. Vitamin C, by contrast, increases the rate of hair growth while also keeping existing hair healthy. Vitamin A focuses on moisturizing the roots and taking care of the scalp's nerve fibers, while various B vitamins keep the hair thick, and the scalp healthy.
The job of vitamin E is to ensure that there is proper circulation of blood in the scalp, resulting in faster hair growth. It does this by increasing the amount of oxygen in the body's cells. Some of the best sources of vitamin E include nuts, whole grains, and leafy green vegetables.
Vitamin C is another nutrient that can lead to hair growth, as one of its main effects is an increase in collagen, which is present in a healthy scalp. Not only can this vitamin help increase hair growth, but it can also result in the ability to keep as much existing hair as possible. This is because it can moisturize, making individual hairs less prone to damage. This is one of the most accessible vitamins for hair growth, as it can be found in foods that include peas, grapefruits, and bananas.
Another one of the most helpful vitamins for hair growth is vitamin A. Like vitamin C, it has moisturizing properties, but this nutrient tends to focus on keeping the roots of the hair lubricated. Additionally, this vitamin prevents the scalp's nerve fibers from being damaged, which is important since only the healthy nerves can signal the folicles to make more hair. Dairy products are considered the best sources of vitamin A, as it is found in milk and cheese, but sweet potatoes and broccoli are also good foods to eat for this nutrient.
Finally, those looking for vitamins for hair growth should take B vitamins, such as B5, which can thicken each strand while also improving the scalp's metabolism. Vitamin B3, or niacin, can lower cholesterol levels in the body, which is helpful since high cholesterol usually reduces circulation of the blood. Another of the B vitamins for hair growth is B2, or riboflavin, which can increase the number of red blood cells so that the scalp can support lots of hair follicles. Leafy greens and whole grains are often the best sources of most B vitamins, but there are also supplements on the market that can be taken instead.
