Abi Jackson says good nutrition leads to strong locks.
Is the quality of our hair all down to our genes, or luck of the draw, as to how quickly our hair grows?
General health may play a part too, and nutrionists Shona Wilkinson and Cassandra Barns, believe what we put into our bodies might make a difference as well.
Here, they highlight seven key nutritional ingredients for growing long, healthy hair.
Selenium: “Not only can selenium benefit skin during healing, but it also helps to keep hair nourished,” says Wilkinson.
“Brazil nuts and wheat germ are a great source of selenium. Other foods rich in selenium are whole grains, fish, seafood and lean meats, sunflower seeds and other nuts, such as pecans and almonds. Also, a good quality supplement can be a great way to improve the condition of your hair.”
Zinc: “Low zinc levels in your system can lead to the deterioration of the protein structure that makes up the hair follicle. This can, in turn, cause hair shedding and hair loss,” says Barns.
“Oysters, pumpkin seeds, ginger root, pecans, Brazil nuts, oats, almonds, turnips and garlic are all great sources of zinc.”
Iron: “If you have low iron levels from your diet, you can develop an iron deficiency, which can lead to thinning hair,” says Wilkinson.
“Essential sources of iron are pumpkin and squash seeds, liver, millet, almonds, prunes, Brazil nuts, beet greens, Swiss chard, dates, lentils, brown rice and broccoli. Alternatively, you can replenish iron deficiency by taking a supplement.”
Amino acids: “Hair is largely made up of keratin, which is a protein containing the amino acids cysteine, lysine, arginine and methionine,” notes Wilkinson. “Of these, lysine and methionine are essential, meaning we must get them from our diet, as we cannot ‘make’ them ourselves.”
Lysine can be found in brewer’s yeast, chicken, dairy, fish, lamb and parmesan; methionine in beans, beef, dairy products, eggs, fish, garlic, liver, onions and sardines; cysteine is also in beans, beef, brewer’s yeast, chicken, cottage cheese, eggs, fish, garlic and liver, while sources of arginine include almonds, beans, cashews, chocolate, dairy products, garlic and peanuts.
Biotin: “Not only can biotin improve the health of skin, it’s also a great way to keep hair strong and revitalised,” says Barns.
“You can increase your biotin intake by eating brown rice and legumes, such as soybeans and lentils. If you have the ‘midday munchies’, perfect biotin-fuelled snacks are nuts and seeds, such as walnuts, pecans, almonds and sunflower seeds.”
Vitamin A: “This vitamin is usually associated with promoting eye health, but this is also a great nutrient for healthy hair. Vitamin A is commonly found in cod liver oil, krill oil, carrots, spinach and peaches,” says Wilkinson.
“However, you must ensure to not go overboard on how much vitamin A you have, as it can in fact contribute to hair loss if taken too much. The maximum daily amount you should consume is 25,000 IU.”
Probiotics: “Regular intake of probiotics can be a great way in helping your hair grow, as each hair is surrounded by nourishing blood vessels, and probiotics attack pathogens (agents of disease) to keep your blood healthy.
"Healthy blood results in nourished hair and can promote hair growth. Kefir, pickles, sauerkraut or miso are all great sources of probotics,” says Wilkinson.
