A high-fat, meat-based diet raises testosterone levels, and that may adversely affect hair follicles. For example, in Japan, male pattern baldness was very rare prior to World War II when the diet was lean and healthy. The Japanese now consume a more fatty, Westernized diet. Baldness is now increasing substantially among Japanese men. Eating low-fat foods may not stop hair loss; but it might help slow down the hair loss.
A wholesome diet, rich in silica, calcium and iron, will help reduce or prevent hair loss. Green, leafy vegetables, especially sea vegetables, are good mineral sources. Raw oats provide silica.
European studies have found that soy protein reinforces hair and stimulates its growth. In one study, The hair growth increased by 15 percent. Tofu and soy milk are good sources of soy protein. Other good sources of protein are: low-fat cheese, eggs, fish, beans, brewer's yeast and yogurt.
Another important nutrient for hair health is silica. Studies in the former Soviet Union have shown that silica therapy slowed hair loss. Organic silica added to shampoo was found to help prevent baldness, stimulate healthier hair growth and assure beautiful shine, luster and strength. Some scientists claim that they have effectively stopped further hair loss by adding silica to their shampoo. This can be applied externally to regrow already lost hair.
Silica is found in the outer coverings of potatoes, green and red peppers and cucumbers. Bean sprouts are also high in silica. Eat whole foods including sprouts.
Vitamin C improves the absorption of iron. Include a good serving of fruits and vegetables in your diet.
Vitamin E is important for healthy hair growth. Eat avocados, nuts, seeds, and olive oil on a regular basis.
