Just like skin, the condition of your hair is an outward sign of inside health. The cells that make up each strand of hair require a regular supply of key nutrients.
As hair is made of protein, ensuring you have enough protein in your diet is crucial for making hair strong and healthy. If you are not consuming enough protein in your diet, your hair is likely to become dry, brittle and weak. Extremely low protein diets may result in hair loss. Choose chicken, turkey, fish, dairy products and eggs as excellent sources of protein along with vegetarian sources such as legumes and nuts.
Iron is an especially important mineral for hair and too little iron (anaemia) is a major cause of hair loss. The hair follicle and root are fed by a nutrient rich blood supply. When iron levels (serum ferritin) fall below a certain point, you may experience anaemia. This disrupts the nutrient supply to the follicle, affecting the hair growth cycle and may result in shedding. Animal products such as red meat, chicken and fish provide iron with a high bioavailability, meaning the iron is readily available to the body. Vegetarians can raise their iron stores by including lentils, spinach and other leafy green vegetables such as broccoli, kale and salad greens.
Vitamin C aids the absorption of iron so foods high in vitamin C are good to eat in conjunction with iron-rich foods. Vitamin C is also an antioxidant so is used readily by the body. The best sources are blackcurrants, blueberries, broccoli, guava, kiwi fruits, oranges, papaya, strawberries and sweet potatoes. Vitamin C helps in the production of collagen that strengthens the capillaries that supply the hair shafts.
Omega-3 fatty acids are important fats our body cannot make itself, and therefore must be obtained through our diet. Omega-3s are found in the cells that line the scalp and also provide the oils that keep your scalp and hair hydrated. Look out for oily fish such as salmon, herring, sardines, trout and mackerel and plant sources including avocado, pumpkin seeds and walnuts.
The sun can damage our hair just like it can damage our skin so ensure you eat foods rich in vitamin E to provide protection for your hair. Nuts are nutritional powerhouses, providing zinc and selenium as well as vitamin E so try to include them as part of a balanced diet.

Vitamin A is needed by the body to make sebum. Sebum is an oily substance created by our hairs sebaceous glands and provides a natural conditioner for a healthy scalp. Without sebum we may experience an itchy scalp and dry hair. Include animal products and orange/yellow coloured vegetables which are high in beta-carotene (which makes vitamin A) such as carrots, pumpkins and sweet potatoes.
Make your own hair mask for a deep, nourishing treatment every two weeks. Whisk an egg yolk and mix with half a mashed avocado and a spoonful of honey. Massage onto damp, clean hair and leave for 30 minutes before rinsing thoroughly.
