In this article, I have discussed the common vitamins and minerals that are required for hair growth and healthy skin.

Dietary Supplements and Their Recommended Doses for Hair Loss

Certain conditions like dry hair indicate a vitamin deficiency or a lack of protein in the diet. The solution is to increase intake of vitamins, minerals and proteins. Vitamins A and C, biotin, iron and zinc are prescribed when the cause of hair loss has been determined. A combination of essential nutrients can stimulate follicular embryonic activity and prevent hair nutrient depletion. Also, there are certain nutrients that have been found to encourage and protect hair follicle health.


Vitamins are extremely important for human hair.

1. Vitamin A:

Protect hair follicle cells from damage caused by free radicals. Deficiency of vitamin A causes dry hair. A therapeutic recommended dose is 25,000 IU per day.

2. B-complex Vitamins:

Reduced levels of vitamin B1 (thiamin), vitamin B2 (riboflavin), niacin and pantothenic acid can contribute to the undernourishment of hair follicle cells.

3. Folic Acid:

A decrease in folic acid may contribute to decreased hair follicle cell division and growth. One of the signs of folic acid deficiency is graying of hair. A therapeutic dose is 1000 mcg per day.

4. Vitamin C:

One of the major functions of vitamin C is to help produce and maintain healthy collagen. It is a type of connective tissue found within the hair follicle. It is also a strong antioxidant and protects cells found in hair follicles. A daily dose of 200 mg is recommended for hair and skin.

5. Vitamin E:

It helps in maintaining integrity of cell membranes of hair follicles, also provides physical stability to cell membranes and acts as an antioxidant. A daily dose of 50 to 400 IU is recommended for hair and skin.



L-Methionine is a sulfur containing amino acid. It supports hair strength by providing adequate amount of sulfur to hair cells, which is essential for normal growth and appearance of hair.
