The Best Foods for Your Hair

You want: More hair staying on your head

Try eating more: Protein

Most iron-rich foods are also good sources of protein, so if your iron intake is adequate, odds are your protein consumption is, too. But if you're getting a lot of your iron from relatively low-protein picks, like certain iron-fortified breakfast cereals, white rice or white bread, that may not be true. According to the American Academy of Dermatology, your body goes into rationing mode when protein intake is too low, and one of they ways the body cuts back on its protein needs is to shut down hair growth, resulting in hair loss. Once you get your protein intake back on track, your strands will follow suit. "It can take a little while to notice the effects of a lack of protein, but I see clients all the time who did a juice cleanse a month or two before they see me and now their hair is falling out," says Bowe. "And it's because there's usually no protein in those cleanses." Meeting the recommended intake of 46 grams per day for women is likely enough to maintain hair health. Getting a mix of lean meats (a 3-ounce piece of chicken, beef or pork generally has about 20 grams), eggs (a large one has 6 grams of protein), Greek yogurt (one non-fat container can pack up to 17 grams) and nuts (a small handful of almonds has 6 grams) will help you reach that goal.
