Defining exactly what a healthy diet is when it comes to preventing hair loss can be a little more complex. Principally, the main vitamins, minerals, and nutrients that one must ingest in some form to maintain healthy hair are vitamin A, all B vitamins-particularly vitamins B-6 and B-12, folic acid, biotin, vitamin C, vitamin E, copper, iron, zinc, iodine, protein of course, silica, essential fatty acids (EFA's, formerly known as vitamin F) and last but not least one must consume water. There are also certain foods that may cause dysfunctions that will contribute to hair loss.
The best way to maintain a healthy vitamin and mineral intake is a good diet. It is not necessary or advisable to go out and buy a bunch of over-the-counter vitamin supplements in order to achieve your suggested nutritional levels. Many over-the-counter vitamins are chemically processed and are not completely absorbed into the system. It is also easy to overdose oneself with over the counter vitamins particularly when taking supplements of fat-soluble vitamins and minerals, causing toxicity and adverse reactions. The likelihood of doing this is far less with food; therefore it is always best to obtain the bulk of your vitamin and mineral requirements from whole foods.
