What Vitamins & Minerals Do Eyebrow Hairs Need to Grow?

The hair on your eyebrows grows in the same manner as the hair on your head and your other body hair. All body hair needs the same nutrients to grow. If your diet regularly lacks nutrients that are critical to growing healthy hair, you’ll notice decreased hair growth all over, not just on your eyebrows.

B Vitamins

B vitamins are vital for all living cells and tissues, including your hair 1. There are a few B vitamins in particular -- vitamin B-1, vitamin B-2 and biotin -- that are crucial for hair growth 1. B vitamins are readily accessible in dairy products, whole grains, vegetables, fruits and meats. A vitamin B deficiency is rare because B vitamins are easily obtained from many different foods.

Your hair relies on blood to carry oxygen and nutrients. Iron is the nutrient that’s responsible for making that happen. Without iron, your blood cells cannot efficiently deliver oxygen and nutrients to hair follicles and other tissues. You can obtain all the iron your body needs by eating eggs, leafy green vegetables, meat and fruits. Iron deficiency is the most common nutritional deficiency in the U.S., according to the Centers for Disease Control.

Protein

Hair strands are made of a protein called keratin. Protein is necessary for healthy hair growth. Vegetarians, those who have an eating disorder like anorexia, or people who follow restricted diets are at the highest risk for not getting an adequate amount of protein. Meat can provide an adequate source of protein, but so can beans, nuts and legumes.

Sulfur

Sulfur works directly with protein and aids in its function. Sulfur can be obtained by eating foods rich in protein. Harvard Health Publications states that there’s no recommended daily allowance of sulfur and that sulfur deficiencies are rare. As long as you consume an adequate amount of protein, you shouldn’t have to worry about your sulfur levels.
