Aging isn’t only accompanied by skin wrinkles. Your hair might take a turn for the worse, too, with the shine and volume of youthful hair usually turning brittle, dull, and thin[1] as the years go on. 

But what causes this change in hair health as the years pass by? It is partly due to collagen production.

Collagens are the structural proteins that build all parts of our bodies: from the skin to internal organs to our hair. But not all collagen is created equal — in fact, there are 28 types of collagen[2] that specialize in specific parts of the body. But hair is not made from collagen, so how can collagen supplements help healthy hair growth?

Read on to find out whether collagen boosts hair health and our review of the best collagen supplements for hair growth.

5 Best Collagen For Hair Growth On The Market In (June. 2023)

Does Collagen Boost Hair Growth?

We know that collagen supplements improve skin elasticity and hydration, giving the skin a more youthful appearance. But do collagen supplements work for hair growth too, or is this a myth portrayed by collagen companies[3]?

Well, recent studies suggest that supplementing collagen significantly improved hair growth,[4] increased hair thickness, reduced hair breakage, and shedding,[5] and even helped prevent age-related hair loss.[6] In fact, compared to the common hair loss prevention medication, finasteride, animal studies show that taking one gram of marine collagen peptides daily has the same impact on halting hair loss and boosting hair regrowth.[6]

But how can collagen supplements help hair growth if the hair is not made from collagen?

Hair is made from another protein: keratin.[7] But collagen can still contribute to hair growth because your body breaks down the collagen into amino acids[8] to rebuild other proteins, such as keratin. 

Secondly, aging is associated with increased oxidative stress in hair follicles,[9] which wreaks havoc on hair, leading to hair loss and premature hair greying.[10] Collagen peptides have antioxidant properties,[11] which might protect hair from higher levels of oxidative stress caused by aging, smoking, ultraviolet light exposure, etc. In fact, marine collagen might be better at reversing the aging effects of ultraviolet light on the skin[12] than two other potent antioxidants: tea polyphenols and casein peptides.

Thirdly, your hair follicles are actually skin cells, which are made from collagen type I[13] and type III.[14] But hair follicles also require another type of collagen to stay healthy: collagen type XVII.[15] That’s why studies show a deficiency in type XVII collagen,[16] as happens with aging, can lead to hair follicle shrinkage and hair loss.

Finally, hormones such as prostaglandins trigger hair growth,[17] and some prostaglandins need to be crosslinked with collagen.

So, now we know collagen can help, which are the best collagen supplements for hair growth? Here are our top five picks for 2023.

5 Best Collagen Supplements For Hair Growth In 2023

Vitauthority Multi Collagen Peptides

Vitauthority Multi Collagen Peptides is one of the cheapest collagen supplements to include collagen from five different sources alongside vitamin C and hyaluronic acid to promote hair follicle health.

  • Includes hyaluronic acid.
  • Provides five collagen types: I-III, V, and X.
  • Free from added sugar or sweeteners.
  • Cheaper than other collagen supplements on the market.
  • Contains proprietary ingredients.

Vitauthority includes five types of collagen from five sources, including grass-fed beef, farm-raised chicken, wild-caught fish, and water-soluble eggshell membrane collagen.

We like that Vitauthority has included hyaluronic acid, which naturally degrades in hair follicles during aging. The lower levels of hyaluronic acid seen in aging are associated with reduced hair thickness and female-pattern hair loss.[9] We don’t yet know if supplementing hyaluronic acid orally can help hair growth, but cell-based studies suggest that hyaluronic acid might promote hair growth.[23]

One customer said the supplement “helped my hair feel thicker,” and another customer noted that they saw a “significant change in my hair” when they stopped taking Vitauthority while they were ill.

The best thing about Vitauthority Collagen Peptides is the cost. At $34.99 for a 40-day supply or, if you subscribe, $26.24 per month, it’s one of the cheapest collagen supplements we’ve reviewed. 

Vitauthority recommends taking one to two scoops of their Multi Collagen peptides powder per day and to take it consistently for at least 60 days to see improvements in hair health. 

Moon Juice Collagen Protect

See Moon Juice Reviews

Moon Juice Collagen Protect is a vegan formula designed to stimulate and protect your own collagen production with fiber and vitamin D embedded in a formula of tocotrienols from mushroom Tremella fuciformis, hyaluronic acid, and organic rice bran.

  • Suitable for vegans.
  • A source of vitamins D and E.
  • Contains hyaluronic acid.
  • Does not contain collagen peptides.

Moon Juice does not contain actual collagen because this is a vegan product. Instead, its ingredients — rice bran, Tremella mushroom, and sodium hyaluronate — are formulated to support your own collagen production. 

Studies suggest that vitamin D deficiency is linked to hair loss.[19] Vitamin D seems to regulate hair follicle cycling[20] and promote hair growth. With so many of us being deficient in vitamin D, it’s surprising that other collagen supplements don’t include vitamin D in their formula.

The Tremella mushroom provides vitamin E, which also acts as an antioxidant and might help protect hair follicle cells from oxidative damage. Studies show that daily supplementation with vitamin E significantly increases levels of vitamin E in sebum,[21] the fat secreted by our skin cells at the hair shaft. Vitamin E might promote hair growth by inhibiting inflammation and oxidative stress[22] in hair follicles. 

One post-menopausal customer said their “hair thickness has quadrupled” after six months of taking this collagen powder. Moon Juice recommends adding one rounded tablespoon to coffee or smoothies to promote healthy hair.

Ancient Nutrition Multi Collagen Protein

Ancient Nutrition Multi Collagen Protein

$12 on orders 25+ and free shipping: HEALTH12

Ancient Nutrition Multi Collagen Protein provides 10 types of collagen from five sources, including clinically-researched fermented eggshell collagen, making it one of the best collagen powders for hair health. 

  • Clinically-researched fermented eggshell membrane collagen.
  • Provides 10 types of collagen: I, III, IV, V, VII, VIII, X, XII, and XXII.
  • Published certificate of analysis for third-party testing.
  • Contains probiotics.
  • Customers complained that the container was only half full.

Ancient Nutrition provides collagen from hydrolyzed bovine collagen peptides, chicken bone broth peptides, hydrolyzed fish peptides, and a proprietary fermented eggshell membrane collagen. This last ingredient is clinically proven to improve hair thickness and hair growth[4] within four weeks, making this one of the best collagen powders for hair growth.

Actually, the eggshell membrane delivers more than just collagen — it contains glycosaminoglycans and polysaccharides, such as glucosamine and chondroitin, which give hair structure and firmness. Plus, Ancient Nutrition includes the probiotic Bacillus coagulans, which might aid protein digestion in the gut, and vitamin C, which is necessary to build collagen and absorb iron.[18] 

We also like that Ancient Nutrition publishes its certificate of analysis to prove there are no heavy metals or other contaminants that can adversely affect hair health.[24]

Some Ancient Nutrition customer reviews say they have noticed that their “hair is thicker” and “seems to be growing faster than normal.”

You should take one scoop of Ancient Nutrition collagen powder daily in water, coffee, or smoothies. It comes in two sizes: 45 servings for $49.95 or 60 servings for $59.95. When you subscribe, you’ll save 15 percent.

Nutrafol Women

Nutrafol Women is clinically proven to reverse hair loss in men and women of various ethnicities[25] and is even recommended as an adjunct to current hair loss treatments.[26]

  • Research-backed supplement.
  • Provides a variety of nutrients for hair growth.
  • Capsules instead of powder. 
  • No gluten, dairy, soy, hormones, drugs, or artificial additives.
  • Uses proprietary ingredients.
  • Only provides collagen types I and III.
  • Expensive.

Hair loss has become increasingly common in women, and it’s thought that, unlike in men, genes are not the main problem — stress is. 

That’s why we like Nutrafol Women, which, alongside providing collagen types I and III, takes a multi-targeted approach to hair loss with hormone-balancing and stress-reducing ingredients to improve hair growth.[27] Clinical research backs up their claims that 90% of women saw an improvement in their hair,[28] with 84% seeing less hair shedding after taking Nutrafol for six months.

Nutrafol includes marine collagen from wild-caught fish alongside herbal extracts, vitamins, and minerals to balance hormones, reduce the impact of stress, and deliver important nutrients for hair growth. 

For example, studies show that ashwagandha can lower morning cortisol levels,[29] a stress hormone that gets incorporated into the hair and disrupts the hair growth cycle.[30] Nutrafol also includes keratin, the protein hair is made from, which delivers the right levels of amino acids to build your own keratin. 

The recommended dosage is four capsules once per day. However, Nutrafol is expensive compared to other supplements on the market. It costs $88 for a one-month supply, working out at almost $3 per day. If you subscribe, though, you can save up to 20%.

SkinnyFit Super Youth

Although it seems expensive initially, SkinnyFit Super Youth collagen peptides powder contains the highest dose of collagen peptides per serving. It also includes vitamin C and hyaluronic acid, nutrients that promote hair growth.

  • Provides five collagen types: I-III, V, and X.
  • 90-day money-back guarantee.
  • A high dose of collagen per serving.
  • Expensive compared to other collagen supplements.
  • Added sweeteners, flavorings, and colors.
  • Not third-party tested.

SkinnyFit includes collagen from four sources: fish, bovine, chicken, and eggshell membranes. 

Out of all the collagen supplements we reviewed, SkinnyFit provides one of the highest doses of collagen peptides per recommended serving: 15.6 grams of collagen. The more amino acids from collagen peptides are available to build keratin, the better for hair growth. So, SkinnyFit’s higher dose of collagen per serving might be the best choice for hair growth.

SkinnyFit also includes 181 milligrams of vitamin C, 50 milligrams of hyaluronic acid, and 200 milligrams of apple cider vinegar. Vitamin C and hyaluronic acid are important for collagen production, and vitamin C increases iron absorption[18] in the gut. As hair loss is a common sign of iron-deficiency anemia, supplementing extra vitamin C might help with hair loss.

Customer reviews say that their “hair and nails seem to be healthier” and that they are “starting to see the improvements with hair and nail growth” after a few weeks of taking SkinnyFit. 

SkinnyFit Super Youth costs $99.95 for a 28-day supply or $79.96 monthly when you subscribe. You can cancel your subscription anytime or take advantage of the 90-day money-back guarantee if not satisfied.

Choosing The Best Collagen Products For Hair Growth

Types Of Collagen

If your goal is hair growth, the type of collagen you choose is crucial. Why? Because collagen comes in different types,[2] but only some types are important for hair.

The main type of collagen you’ll want is collagen type I.[13] This is the most prevalent type of collagen in the human body and is present in bone, connective tissues, and skin — including hair follicles. 

Collagen type I is fibrillar, meaning fiber-forming, but there are also important non-fibrillar[31] collagen types for hair. The main one for hair health is collagen type XVII, which helps stabilize keratin proteins.

Sources Of Collagen

The most common sources of collagen peptides in supplements are bovine skin, fish bones or skin, chicken bones, and eggshell membranes. 

We do not have much evidence for the best source of collagen for hair, but according to the research we have so far the best source of collagen for hair growth is eggshell membrane collagen.

Hydrolyzed vs. Non-Hydrolyzed

Make sure you buy a supplement with hydrolyzed collagen proteins, such as the five collagen supplements we reviewed here. This means the proteins have been broken down with enzymes to make smaller peptides that are easier to digest and absorb.

Added Nutrients

We recommend choosing a collagen supplement with added vitamins, minerals, and herbs that are proven to aid hair growth. For example, vitamin D, vitamin C, B vitamins, zinc, and other micronutrients have been shown to combat hair loss[32] and improve hair growth.

How To Use Collagen For Hair Growth

Take collagen supplements as recommended on the package unless otherwise directed by a healthcare practitioner. This is usually mixed with water or other liquid to be taken orally. 

You can also add collagen powders to cooking if you don’t like the taste, such as in pancakes, cakes, bread, etc., but do not cook products with probiotics in them, or you will destroy the live bacteria. Also, accurate dosing is more difficult in cooked products. 

Some people wonder: when is the best time to take collagen for hair growth? The answer is — it doesn’t matter! What’s important is you take it daily and consistently to see results.

But there is another way to use collagen for hair growth: directly on your hair. Studies suggest using collagen products instead of other hair styling products can reduce excess sebum production,[33] restore healthy pH on the scalp, and even reduce skin inflammation.

Safety & Precautions

Side effects are very uncommon with collagen supplements, but here are some rare side effects and issues with collagen supplements to watch out for.

Allergic Reaction

Collagen supplements are not regulated by the Food and Drug Administration, so companies are not required to test their collagen powders for purity. As marine collagen powders might be contaminated with other types of seafood, they might cause an allergic reaction[34] in some people.


Some collagen supplements might also be contaminated with heavy metals such as cadmium,[35] making third-party testing all the more important.

Gut Symptoms

It’s hard to take too much collagen, but one symptom might be digestive symptoms such as bloating, gas, and indigestion.

Final Thought

Many people take collagen for its anti-aging properties and reduction of skin wrinkles, but new studies suggest that collagen supplements can aid hair growth and even reverse hair loss.

There’s not too much research on the impact of collagen supplements on hair growth yet, but if you’re suffering from female-pattern hair loss, it’s worth taking a collagen supplement to see if it helps. 

Studies suggest you’ll want to supplement collagen daily for at least four weeks to see improvements in hair growth, but some companies say you should take their product for at least six months before deciding whether it works for you.

We recommend taking a collagen powder supplement with eggshell membrane collagen plus added vitamins and minerals to aid hair health, such as SkinnyFit Super Youth or Nutrafol Women.

Frequently Asked Questions

Is collagen or biotin better for hair growth?

Both collagen and biotin might benefit hair growth, but the evidence is not strong in either case. There are no studies comparing collagen and biotin for hair growth, so it’s impossible to say which is better.

What is the best collagen for hair growth?

We do not have enough research to confirm the best collagen for hair growth. Nevertheless, the best studies assessing collagen for hair growth so far used eggshell membranes.

How long does it take for collagen to work for hair growth?

Studies suggest hair growth was significantly improved after just four weeks of supplementing eggshell membrane collagen, but some companies say you should take their product for at least six months before deciding whether it works for you.

Can collagen help regrow thinning hair?

Collagen might help regrow thinning hair. However, the studies used collagen with added nutrients and herbs, so it’s impossible to say whether it’s due to the collagen or something else.

How much collagen should I take daily for hair growth?

At least half a gram of collagen peptides per day should be taken for noticeable effects.
