Hair is made up of protein called keratin. And proteins are formed from amino acids. Most amino acids are made by the body. Others called “essential amino acids” must be obtained from the diet. Amino Acids with importance on hair growth like Methionine and Homocysteine contain sulfur which is an important mineral for healthy hair growth. Arginine produces nitric oxide in blood vessel linings which causes blood vessels to relax and dilate, promoting an increased blood flow. This is important for scalp circulation.

Aside from proteins, unrefined carbohydrates like beans, whole grains, and vegetables will provide the fiber and nutrients your body needs. These contain vitamins for thinning hair and other hair loss conditions and are converted to glucose for energy at a steady, balanced rate.

In contrast, refined carbohydrates like white rice, white flour, and cakes lack fiber and nutrients and will rarely contain naturally occuring vitamins for promoting hair growth.

When it comes to fats, the most beneficial fats to consume are monounsaturated and polyunsaturated fats. Examples of monounsaturated fats are almond, avocado and olive oils. Polyunsaturated fats include Alpha Linolenic Acid (Omega 3), Gamma Linolenic Acid (GLA), and Linoleic Acid (Omega 6). These three types of essential fatty acids are the most powerful 5-Alpha Reductase and DHT blockers known to prevent thinning hair.

GLA is found in evening primrose oil, borage (starflower) oil and black currant seed oil. Omega 6 and Omega 3 can be obtained from certain plant oils like seeds, rapeseed oil, walnuts, pumpkin and soya. Flax seed (linseed) oil is also very high in Omega 3. However, the richest source of Omega 3 comes from oily fish especially salmon, herring and mackerel.

Essential fatty acids support skin and hair growth. Omega 3 and omega 6 fatty acids are useful in maintaining healthy hair. By increasing these levels of essential fatty acids, one can slow down hair loss and prevent thinning hair.

Omega-3 fatty acids can help with blood circulation and cell growth, which are useful for your hair follicles. They help to increase nutrient absorption at the hair follicles, reduce stress and enhance the immune system. A deficiency in essential fatty acids produces symptoms such as dry, scaly or flaky skin, dandruff, dry, brittle hair or eczema. All of which may lead to hair loss.
