How to grow thick hair naturally
Eat foods rich in zinc
If you are a vegetarian, you should pay attention to the amount of zinc in your diet. One study found that people who don’t eat meat are at higher risk of zinc deficiency, which is one of the causes of hair loss. So if you’re a vegetarian, you’ll need to get your zinc from other sources.
Oysters, meat and fish contain plenty of zinc. Grains, legumes, dairy products and seeds contain small amounts of zinc.
