Is bone broth good for hair growth? Bone broth will not regrow hair on its own, but it is a genuinely useful part of a hair-friendly diet. It delivers the raw materials your body uses to build hair, mainly protein, collagen-derived amino acids like glycine and proline, and trace minerals such as zinc and iron. Hair is made almost entirely of a protein called keratin, so a steady supply of protein and these building blocks helps your body grow the strongest, healthiest hair it is capable of. What bone broth cannot do is override genetics, hormones, or a medical cause of shedding. Think of it as good nutrition that supports the hair you have, not a cure for hair loss.

What is bone broth, and what is actually in it?

Bone broth is made by simmering animal bones and connective tissue, usually beef, chicken, or fish, in water for several hours, often with a splash of vinegar and some vegetables. That long, slow cook pulls collagen, gelatin, amino acids, and minerals out of the bones and into the liquid. It is the same idea as a traditional stock, just simmered longer so more of the collagen dissolves.

The nutrition varies a lot depending on the bones, the cooking time, and whether it is homemade or shop-bought. In general, a cup of bone broth gives you a modest amount of protein (roughly 6 to 12 grams), gelatin, and small amounts of minerals. It is not a dense multivitamin, and it is lower in protein than a chicken breast or a scoop of protein powder. Its value for hair is that it is an easy, gut-friendly way to add quality protein and amino acids to your day.

The nutrients in bone broth that relate to hair

• Collagen and gelatin: The main protein in bone broth. Your body cannot use it whole. It is digested into amino acids that your body then uses to build its own proteins, including keratin.
• Glycine and proline: Two amino acids that are abundant in collagen. Glycine in particular is involved in making keratin and other structural proteins.
• Minerals: Small amounts of calcium, magnesium, phosphorus, and sometimes zinc and iron. Iron and zinc are two of the most important minerals for hair.
• Protein overall: The single most useful thing bone broth adds. Hair growth slows when protein intake is too low.

How does bone broth support hair growth?

Hair grows from follicles in cycles: a long growth phase (anagen), a short transition phase (catagen), and a resting and shedding phase (telogen). Each strand is built by follicle cells that need a constant supply of protein, energy, and micronutrients. When that supply falls short, more follicles slip into the resting phase early and shedding increases. This is why crash diets and very low protein intake are a well-known trigger for temporary hair shedding.

Bone broth helps at the nutrition level in a few honest ways.

1. It adds protein, the material hair is built from

Hair is around 90 percent keratin, a protein. If your diet is short on protein, your body prioritises vital organs over hair, and growth can suffer. Bone broth is one easy way to top up daily protein, especially for people who struggle to eat enough, such as older adults or those recovering from illness.

2. It provides amino acids your body uses to build keratin

Once digested, the glycine and proline from collagen join the pool of amino acids your body draws on to make its own proteins. Your body decides where those amino acids go, and healthy follicles are active users of them. This is support, not direct delivery: eating collagen does not mean collagen appears in your hair shaft.

3. It contributes small amounts of hair-relevant minerals

Iron and zinc deficiencies are two of the most common nutritional causes of shedding, especially in women. Bone broth contains modest amounts of both. It is not a reliable treatment for a genuine deficiency (that needs testing and often a supplement from your GP), but as part of a varied diet it adds to your daily intake.

4. It is easy on digestion, so nutrients are well absorbed

Bone broth is gentle and hydrating, which is one reason it is popular during recovery from illness. Good overall nutrition and hydration create the background conditions in which hair grows well. There is no strong evidence that bone broth uniquely heals the gut, so treat those bigger claims with caution.

Does eating collagen actually reach your hair?

This is the most misunderstood part. When you drink bone broth or take a collagen supplement, your digestive system breaks the collagen down into individual amino acids and short peptides. Those are absorbed into your blood and become part of the general amino acid pool. Your body then uses them wherever it needs protein.

So the honest picture is: collagen in equals amino acids available, not collagen delivered to follicles. Some small studies on collagen peptides suggest possible benefits for skin elasticity and hydration, but the evidence specifically for hair growth is limited and early. That does not make bone broth useless. It makes it a helpful protein source rather than a targeted hair treatment. Set your expectations there and you will not be disappointed.

Bone broth versus other hair-nutrition options

Bone broth is one of several ways to feed your hair from the inside. Here is how it compares to other common approaches, so you can decide where it fits for you.

The takeaway: the strongest results come from combining good nutrition inside with good scalp care outside. Bone broth sits comfortably in the nutrition column alongside whole foods and, where useful, a targeted hair vitamin.

How do you add bone broth to your diet for hair?

You do not need to overhaul your meals. A realistic goal is 2 to 3 cups a week as part of an already varied, protein-rich diet.

• As a soup or stew base: Swap water for bone broth when you cook grains, soups, or stews. Easy, no new habit needed.
• As a warm drink: Sip a mug of seasoned broth in place of an afternoon coffee, especially in winter.
• Blended into savoury dishes: Use it in risottos, gravies, and sauces to add flavour and a little extra protein.
• Homemade for control: Simmer beef or chicken bones with a splash of vinegar and some vegetables for several hours, then strain. This lets you avoid the high salt levels found in some shop-bought versions.

Is there a vegetarian or vegan version?

Yes. You will not get animal collagen, but you do not strictly need it, because your body builds its own collagen and keratin from amino acids that plants also provide. A rich vegetable broth plus a protein-focused diet gives similar hair-supporting nutrients. Good plant sources include:

• Beans, lentils, and chickpeas for protein and iron
• Tofu and tempeh for complete protein
• Pumpkin seeds and cashews for zinc
• Leafy greens and citrus for the vitamin C that helps your body make its own collagen

What else does hair need beyond bone broth?

Bone broth is one piece of a bigger picture. If you care about hair health, these are the nutrients with the best evidence behind them, and where to get them.

• Protein: Eggs, fish, poultry, dairy, beans, tofu. The foundation of all hair growth.
• Iron and ferritin: Red meat, lentils, spinach, fortified cereals. Low iron is a leading nutritional cause of shedding in women.
• Zinc: Shellfish, seeds, nuts, wholegrains. Involved in follicle repair.
• Biotin and other B vitamins: Eggs, nuts, wholegrains. Contribute to the maintenance of normal hair.
• Vitamin D: Sunlight, oily fish, fortified foods. Low levels are linked with some types of shedding.
• Vitamin C: Citrus, peppers, berries. Helps your body make its own collagen and absorb iron.

If you eat a varied diet with enough protein and these micronutrients, you have already done most of what food can do for your hair.

When shedding is more than a diet problem

Diet supports hair, but it does not explain every case of thinning. If you notice a sudden increase in shedding, a widening parting, or hair coming out in clumps, that points to something a bowl of broth will not fix. Common causes include iron deficiency, thyroid issues, stress-related telogen effluvium, hormonal changes, and genetic (androgenetic) hair loss.

The sensible first step is a GP visit and a simple blood panel (ferritin, full blood count, thyroid, vitamin D). Treating an underlying cause is far more effective than any single food. Good nutrition, including bone broth if you enjoy it, then works alongside that. For everyday habits that genuinely help, our six tips for healthy hair is a practical place to start.

Supporting your hair from the outside, too

Feeding hair from within works best when you also look after the scalp and the strands you already have. Gentle, sulfate-free cleansing keeps the scalp comfortable, and the right actives can leave hair looking thicker and fuller.

Frequently asked questions

How often should I drink bone broth for hair?

Around 2 to 3 cups a week is a sensible amount as part of a varied, protein-rich diet. There is no proven "hair dose", so more than that offers no guaranteed extra benefit.

Can bone broth reverse hair loss?

No. Bone broth supports general hair health by adding protein and amino acids, but it cannot reverse genetic (pattern) hair loss or a medical cause of shedding. For those you need the right diagnosis and treatment from a GP or specialist.

How long before I see any difference?

Hair grows slowly, about 1 cm a month. Any diet change shows up over months, not weeks. Give a genuinely improved diet at least 3 to 6 months, and manage expectations: better nutrition supports the hair you can grow, it does not create new density where follicles have been lost.

Is shop-bought bone broth as good as homemade?

It can be, but read the label. Some shop versions are high in salt and low in real protein. Homemade lets you control the ingredients and simmer long enough to extract more collagen.

Is there a vegetarian alternative to bone broth?

Yes. A rich vegetable broth plus plant proteins (beans, lentils, tofu), zinc-rich seeds, and vitamin C foods gives similar hair-supporting nutrition. Your body builds its own keratin from amino acids, so you do not strictly need animal collagen.

Is bone broth safe during pregnancy?

Bone broth is generally considered safe in pregnancy and can be a comforting, nourishing drink. Choose low-salt options and, as with any dietary change in pregnancy, check with your midwife or GP first.

Does bone broth help scalp health?

Indirectly. Good overall nutrition and hydration support a healthy scalp, and a healthy scalp is a better environment for hair. Bone broth is not a targeted scalp treatment, though. For scalp comfort, gentle sulfate-free cleansing matters more.

Should I take a collagen supplement instead?

Collagen supplements and bone broth work the same way: both are digested into amino acids. A supplement is more convenient and consistent in dose, while broth is a whole food you can enjoy as part of a meal. Neither is a substitute for treating an underlying cause of hair loss.

The bottom line

Bone broth is a genuinely helpful part of a hair-friendly diet. It adds protein and the amino acids your body uses to build keratin, plus small amounts of hair-relevant minerals, in an easy, comforting form. What it is not is a cure. It will not override genetics, hormones, or a medical cause of shedding, and collagen you eat does not travel straight to your follicles. Enjoy it as good food, pair it with a varied protein-rich diet and sensible scalp care, and see a GP if your shedding is more than everyday. Do those things together and you give your hair the best support nutrition can offer.
