According to Natural News, because hair is made up of protein, fat, water and carbohydrates, a protein deficiency may cause weak hair or hair loss. This can be especially true for vegetarians. Adding protein to your diet may help to enrich the health of your hair. Protein powder shakes are a simple and quick way to do that. A nutrient-rich diet full of fresh fruits and vegetables can also support healthy hair, along with herbal and vitamin supplements. If you are concerned about your hair and are experiencing any unusual symptoms such as large amounts of hair loss, contact your physician.
Purchase a quality protein shake mix with whole foods, vitamins and minerals that can contribute to hair health. Look for ones that contain vitamin E, amino acids and herbs.
Make a shake as directed on the label. Letha Hadady suggests in her book, "Asian Health Secrets: The Complete Guide to Asian Herbal Medicine," making a shake with pineapple juice, which helped her hair considerably.
Drink the shake every morning for several weeks and see if you notice results. Also try shampooing your hair with a protein-rich formula, whenever hair feels oily, or several times a week.
