Can diet affect hair growth?

We’ve all heard the expression, “You are what you eat,” and that definitely applies to your hair. By eating a well-balanced diet, rich in minerals, vitamins, protein and iron, your hair can get all the nutrients it needs to grow healthy and strong. Since most of your hair is made up of protein, not eating enough in your diet, can cause some of your follicles to go into their resting, or non-growing, phase. Iron is also essential because without it you may experience hair loss. In addition to eating a healthy, balanced diet, taking a multivitamin can also ensure that you are getting all the nutrients your body and your hair need.
