When your hair strands turn brittle, your nutritionist or trichologist will often advise you to increase your consumption of protein-heavy foods or whey protein for hair loss. This is because 88-90% of each of your hair strands is made up of the protein keratin. In fact, protein makes up 20% of the human body. This is why it’s important to maintain a healthy protein intake through your diet.

What Happens When Your Protein Intake is Curtailed?

If your body doesn’t get enough protein it will simply start rationing it. It’ll use what it does get for important functions like essential cell growth and repair and production of enzymes, hormones, and antibodies. 

Since hair growth isn’t regarded as crucial to normal bodily function, it isn’t allocated any protein when the amount available is limited. This makes it vital to consume enough protein for hair growth. The growth cycle for your hair follicles alternates between the growing phase and a resting/shedding phase. If they don’t receive enough protein during the former, they enter the latter instead of growing. This is why when you have a protein deficiency, you might see higher than normal hair loss in addition to your follicles turning dry or brittle. 

Which Foods Provide the Right Protein for Hair Growth?


Eggs are one of the best sources of protein you’ll come across. Not only are they rich in protein, but they also provide biotin, which is essential for your follicles to produce keratin. Eggs also contain other nutrients for hair growth, like selenium and zinc.

Lean Meats

Chicken, turkey breast, and lean beef are all delicious additions to your diet and great sources of protein for hair growth. They also provide iron and vitamin B and are low in fat and calorie content. 


Fatty fish like salmon tend to be rich in protein as well as omega-3 fatty acids, which have been linked to increased hair volume. 


Almonds and peanuts are filled with protein, vitamins, and essential nutrients, in addition to being a delicious snack you can enjoy any time of the day. Lentils and grains like oats and quinoa are just good and a big part of the diet in vegetarian cultures, precisely because they’re rich in protein.

What Are Some Other Ways to Provide Protein for Hair Growth?

Protein Packs

These are applied externally to help moisturize and nourish the hair. Keratin treatments are a very common form of external application that seals the hair shafts with a coating of protein to eliminate frizz and add shine.

Whey Protein for Hair Loss

Whey is basically the liquid created as a by-product of cheese production. Whey protein is a mixture isolated from this liquid. It is a rich source of amino acids, or protein molecules, and is a good source of concentrated protein for hair growth.

Balanced protein consumption is absolutely crucial, whether you’re experiencing hair growth issues or not. Sometimes, however, even a balanced diet may not provide the full complement of nutrients your hair follicles need. You can always consider incorporating a supplement into your diet to aid hair growth.
