Hair is made primarily of special amino acids, otherwise known as proteins. We suggest eating a portion of high-protein food (eggs, milk, fish, cheese, nuts, seeds, pulses) with breakfast and lunch to provide your hair with the best daily nutrients for growth.

Research shows that lack of B Vitamins, especially Vitamin B12, can speed up the hair greying process. Help sustain your intake of Vitamin B by eating B12 rich foods, such as fortified cereal, milk, yogurt, egg yolks, and salmon.

Supporting your hair’s growth with a hair-healthy diet is very important. Try eating complex carbohydrates (chickpeas, beans, cereals, whole-grains) with every meal, and a portion of high-protein food (eggs, milk, fish, cheese, nuts, seeds) twice a day.
