6 nutrients essential for hair growth

1. Vitamin B complex

In addition to vitamin B7, riboflavin, biotin, folate, and vitamin B12 are vital for hair growth. These nutrients nourish the scalp and hair follicles. Biotin and riboflavin deficiencies are rare in the United States, as the recommended amount can be obtained through diet

  • Eggs
  • Whole grains
  • Fortified breakfast cereals
  • Legumes
  • Citrus fruits
  • Avocados
  • Meat
  • Poultry
  • Fish
  • Liver

2. Iron

Iron deficiency (anemia) can cause hair loss, as iron boosts oxygen circulation to the hair roots. Iron deficiency can occur with menstruation and pregnancy, as well as affect vegetarians.

Good sources of iron include:

  • Grass-fed beef
  • Clams
  • Oysters
  • Beans
  • Lentils
  • Spinach
  • Pumpkin seeds
  • Sesame seeds

3. Vitamin C

Vitamin C promotes hair growth by preventing oxidation and free radical damage associated with aging and inflammation. It also promotes collagen synthesis, which is critical to hair structure. Since vitamin C increases intestinal absorption of iron, people with iron deficiency should take vitamin C to improve iron absorption in the body.

Foods rich in vitamin C include:

  • Green peppers
  • Cabbages
  • Lemons
  • Oranges
  • Leafy greens
  • Potatoes
  • Tomatoes

  • Fatty fish such as tuna, mackerel, and salmon
  • Foods fortified with vitamin D such as dairy products, orange juice, and soy milk
  • Egg yolk
  • Cheese
  • Beef liver

5. Zinc

Zinc plays a crucial role in the production of proteins in your hair. Signs of low zinc levels include hair loss and poor wound healing. Since your body does not produce zinc on its own, it is necessary to get it from foods.

Zinc levels are usually low in these conditions:

Zinc can be found in foods such as:

  • Shellfish
  • Meat
  • Beans
  • Nuts and seeds

6. Omega-3 fatty acids
