While your hair's thickness is often based on genetics, nutritional deficiencies can affect its potential for shine and fullness. If you're wondering how to have thick hair, these 5 vitamins could be your answer.Vitamin C
Vitamin C is necessary to produce collagen, which is essential for the connective tissue that holds hair, skin and nails together. Stress alone can deplete vitamin C, so make sure you're getting your fill of fruits, vegetables like bell peppers and dark leafy greens, and herbs like basil and parsley. Iron
Iron deficiency is pretty common, and can lead to anemia, which causes hair loss and thinning. Stock up on lean meats, beans, and whole grains. Zinc
Zinc is responsible for cell reproduction and repair. Got dandruff? Lack of zinc may be the culprit. Oysters and nuts will ensure your levels are appropriate. Selenium
Selenium aids the thyroid in transporting hormones to blood cells, and a lack of selenium can be behind numerous health problems, including thinning hair. Fish, shellfish, red meat, grains, eggs, chicken, liver, and garlic are all good sources of selenium.
