If you are not getting enough protein through your diet, you may experience excessive hair shedding (telogen effluvium). You may also find that your hair will not grow past a certain length.
Why are Proteins Important for Hair?
Your body uses proteins to build tissue cells — including the cells of your hair, skin and nails. Eighty to eighty-five percent of your hair is composed of a protein called keratin. Dietary proteins are your hair’s building blocks — they make your hair strong and help keep it in its growing (anagen) phase.
Without sufficient available protein, your hair can become brittle and fall out before it reaches its full length. This is one of the reasons why people with a low-protein diet often find their hair will not grow past a certain length.
If you experience hair loss from lack of protein, try not to worry — this is reversible, and relatively easy to correct with adjustments to your diet. For a start, we suggest including at least 120g of a protein rich food with breakfast and lunch.
Good Sources of Protein
The best sources of proteins include fish, eggs, red meat, poultry, cheese, beans, quinoa, tofu, seitan, legumes, nuts. Be wary of cheese, though: it can trigger eczema and dandruff in some people, and also takes over two hours to digest.
Eggs: The Perfect Protein for your Hair
The amino acids (proteins) found in egg whites are the most complete and easily absorbed form of protein for your body. Dietary protein is essential to hair growth and health, because hair is made primarily of keratin – a special hair protein that gives your strands their strength, flexibility and elasticity. We suggest eating up to two eggs a day, at either breakfast or lunch.
