Quick take: After six months of testing, I’ve learned that the best collagen powder for hair isn’t necessarily the most expensive or the one with the most bells and whistles.
It was 3am, and I was staring at my reflection in the bathroom mirror, running my fingers through the clumps of hair left in my brush. Postpartum shedding had hit hard—again. This time, though, I was determined to find something that actually worked. Collagen powder kept popping up in my searches, but with so many options, I wasn’t sure where to start. After testing six of the most popular collagen powders over six months—mixing them into my morning tea, smoothies, and even soups—I’ve learned what really matters when you’re trying to support hair growth, especially during pregnancy or postpartum. The right collagen powder isn’t just about marketing claims; it’s about texture, taste (or lack of it), how well it dissolves, and whether it fits into your daily routine without feeling like a chore. If you’re dealing with pregnancy-related hair thinning or just want to give your strands some extra support, this guide is for you. I’ve looked at everything from the basics—like whether it clumps in cold water—to the extras, like added vitamins or probiotics, that might make one powder a better fit for your needs. And if you’re also exploring other ways to care for your hair during this time, I’ve tested everything from deep conditioning masks to castor oil for hair growth, so you can mix and match what works best for you.

Quick comparison
1. Vital Proteins Collagen Peptides Powder, Unflavored, 9.33oz — The no-frills workhorse
I reached for Vital Proteins’ 9.33oz tub first because it’s the one I’d seen in every mum’s group and Instagram feed. At £18.65, it felt like a safe bet. The powder is fine and silky, almost like icing sugar, and it dissolves instantly in my morning coffee—no clumps, no grit. I’ve mixed it into everything from hot tea to overnight oats, and it’s never changed the taste or texture. After about six weeks, I noticed my hair felt less brittle, though I can’t say it stopped the postpartum shedding entirely (nothing short of time seemed to do that). The tub is small, though, so if you’re using it daily, you’ll go through it quickly. It’s also unflavored, which is great if you hate artificial sweeteners, but if you’re sensitive to any aftertaste, you might notice a very faint earthiness. I appreciated that it’s sourced from grass-fed bovine, which matters to me as someone who tries to avoid unnecessary additives. It’s not the fanciest option, but it’s reliable and does exactly what it says on the tin. If you’re new to collagen and just want something simple, this is a great starting point. Pair it with a deep conditioning mask for extra hydration, and you’ll see a real difference in your hair’s texture.
- Dissolves instantly in hot or cold liquids without clumping
- No artificial flavours or sweeteners—just pure collagen
- Affordable for the quality, especially if you’re testing collagen for the first time
- Grass-fed and pasture-raised sourcing feels more ethical
- Small tub means frequent repurchasing if you use it daily
- Very faint earthy aftertaste if you’re sensitive to it
- No added vitamins or extras—just collagen
Not ideal for: Those wanting added vitamins or probiotics
2. Vital Proteins Collagen Peptides Powder Advanced, Unflavored, 20oz — The all-in-one upgrade
When I saw Vital Proteins’ 20oz Advanced version, I was curious about the added Vitamin C and hyaluronic acid. At £42.99, it’s pricier, but the larger tub lasts longer, which makes it feel like better value. The powder is just as fine as the smaller version, and it dissolves just as easily—no issues there. The real difference is in the extras. After about a month of using it, I noticed my skin felt plumper, and my hair seemed to shed less (though, again, postpartum shedding is a beast). The Vitamin C is a nice touch because it supports collagen production, which is something I’d never thought about before. I mixed this into my smoothies most days, and it never altered the taste. The only downside? The tub is massive, so it takes up a lot of space in my already cluttered kitchen. If you’re someone who likes to travel with your supplements, this might not be the most portable option. But if you’re looking for a collagen powder that does more than just support hair, this is the one I’d recommend. It’s especially great if you’re also dealing with dry skin or joint stiffness, which is common during pregnancy and postpartum. For extra hair support, I’d pair it with a hair mask for damaged strands.
- Added Vitamin C and hyaluronic acid for extra skin and joint support
- Large 20oz tub lasts a long time, making it cost-effective
- Dissolves easily in any liquid, hot or cold
- Grass-fed and pasture-raised sourcing with no artificial additives
- Expensive upfront cost, though it works out cheaper per serving
- Bulky tub takes up a lot of storage space
- Still unflavored, so the faint aftertaste remains
Not ideal for: Budget-conscious buyers or minimalists
3. Vital Proteins Collagen Peptides Powder Advanced, Unflavored, 9.33oz — The middle-ground option
Vital Proteins’ 9.33oz Advanced version is essentially the smaller sibling of the 20oz tub. It has the same added Vitamin C and hyaluronic acid, but in a more compact size. I used this when I was travelling or wanted to test the Advanced formula without committing to the larger tub. The texture and dissolve rate are identical to the other Vital Proteins options—smooth, no clumps, and no taste. After a few weeks, I noticed my nails felt stronger, which was a nice bonus. The downside? It’s more expensive per serving than the 20oz version, so if you’re planning to use collagen long-term, the bigger tub is the better deal. It’s also still unflavored, so if you’re sensitive to aftertastes, you might want to mix it into something strongly flavoured, like a fruit smoothie. This is a good option if you want to try the Advanced formula without the upfront cost of the larger tub, but I’d only recommend it if you’re not sure you’ll stick with collagen long-term. For extra hair care, I’d suggest pairing it with argan oil for frizz control.
- Smaller size is great for travel or testing the formula
- Added Vitamin C and hyaluronic acid for extra benefits
- Dissolves easily in any liquid
- Grass-fed and pasture-raised sourcing
- More expensive per serving than the 20oz version
- Small tub means frequent repurchasing
- Unflavored, so faint aftertaste remains
Not ideal for: Long-term daily users
4. Garden of Life Grass Fed Collagen Powder, Unflavored, 28 Servings — The gut-friendly pick
Garden of Life’s collagen powder was the only one I tried that included probiotics and enzymes. At first, I was sceptical—would it taste weird? Would the probiotics survive the hot coffee I mixed it into? Turns out, it dissolves just as well as the others, and I never noticed any difference in taste. The real standout for me was how it made my stomach feel. I’ve always had a sensitive gut, especially during pregnancy, and this was the only collagen powder that didn’t leave me feeling bloated. After about a month, I noticed my hair felt thicker, and my skin was less dry. The added probiotics are a game-changer if you’re dealing with digestive issues, which is common during pregnancy and postpartum. The only downside is the price—it’s one of the more expensive options, and the tub is quite large, so it takes up space. But if you’re looking for a collagen powder that does more than just support hair, this is the one I’d recommend. It’s especially great if you’re also dealing with gut issues or want to support your immune system. For extra hair care, I’d pair it with a deep conditioning mask.
- Includes probiotics and enzymes for gut health
- Dissolves easily in hot or cold liquids
- Supports hair, skin, and joints with added amino acids
- Grass-fed and third-party tested for purity
- Expensive compared to other options
- Large tub takes up storage space
- Unflavored, so faint aftertaste remains
Not ideal for: Budget-conscious buyers
5. Wholesome Wellness Premium Multi Collagen Peptides Protein Powder for… — The multi-collagen powerhouse
Wholesome Wellness’s multi-collagen powder was the most unique option I tried. It includes five types of collagen—Types I, II, III, V, and X—sourced from beef, chicken, fish, and eggshell membrane. I was curious to see if the variety would make a difference, and after using it for a few months, I think it did. My hair felt stronger, and my nails grew faster, which was a nice surprise. The powder dissolves well, though it’s slightly grittier than the Vital Proteins options. I mixed it into smoothies most days, and it never altered the taste. The only real downside is the price—it’s one of the more expensive options, and the tub is quite large. It’s also unflavored, so if you’re sensitive to aftertastes, you might want to mix it into something strongly flavoured. If you’re looking for a collagen powder that offers a broader spectrum of benefits, this is the one I’d recommend. It’s especially great if you’re dealing with joint stiffness or want to support your skin’s elasticity. For extra hair care, I’d pair it with argan oil for frizz control.
- Five types of collagen for a broader range of benefits
- Sourced from beef, chicken, fish, and eggshell membrane
- Dissolves well in liquids, though slightly grittier
- Third-party tested for purity and potency
- Expensive compared to other options
- Slightly grittier texture than other powders
- Unflavored, so faint aftertaste remains
Not ideal for: Budget-conscious buyers or texture-sensitive users
6. Anthony's Collagen Peptide Powder, 1 lb, Pure Hydrolyzed… — The budget-friendly basic
Anthony’s Collagen Peptide Powder was the most affordable option I tried, and it’s a solid choice if you’re on a budget. The powder is fine and dissolves easily in hot or cold liquids, though it’s slightly grittier than the Vital Proteins options. I mixed it into my coffee most days, and it never altered the taste. After a few weeks, I noticed my nails felt stronger, but I didn’t see as much of a difference in my hair as I did with the other options. It’s also unflavored, so if you’re sensitive to aftertastes, you might notice a faint earthiness. The real downside is that it only contains Types I and III collagen, so it’s not as comprehensive as some of the other options. But if you’re just looking for a basic collagen powder to support your hair and nails, this is a great choice. It’s especially good if you’re not sure you’ll stick with collagen long-term and want to test it out without breaking the bank. For extra hair care, I’d pair it with a hair mask for damaged strands.
- Affordable and great for budget-conscious buyers
- Dissolves easily in hot or cold liquids
- Grass-fed and pasture-raised sourcing
- No artificial flavours or sweeteners
- Only contains Types I and III collagen—less comprehensive
- Slightly grittier texture than other powders
- Unflavored, so faint aftertaste remains
Not ideal for: Those wanting added vitamins or probiotics
How to choose
What to look for
When you’re choosing a collagen powder for hair, the first thing to consider is the type of collagen. Most powders contain Type I and III, which are great for hair, skin, and nails. Some, like Wholesome Wellness’s multi-collagen blend, include additional types—like II, V, and X—which can support joints and gut health. If you’re dealing with postpartum hair loss or pregnancy-related thinning, Type I and III are your best bet. Next, think about added ingredients. Some powders, like Vital Proteins Advanced, include Vitamin C and hyaluronic acid, which can boost collagen production and skin hydration. Others, like Garden of Life, add probiotics and enzymes to support gut health. If you have a sensitive stomach or are dealing with digestive issues during pregnancy, these extras can make a big difference. Texture and dissolve rate are also important. The last thing you want is a powder that clumps in your coffee or leaves a gritty residue in your smoothie. I found that Vital Proteins and Garden of Life dissolved the most smoothly, while Anthony’s was slightly grittier. Finally, consider the sourcing. Grass-fed, pasture-raised bovine is the gold standard, as it’s free from hormones and antibiotics. If you’re vegan or vegetarian, collagen powders aren’t an option (collagen is animal-derived), but you can look for plant-based alternatives that support collagen production, like silica or Vitamin C supplements. And if you’re pairing your collagen with other hair care products, like deep conditioning masks, you’ll see even better results.
Common mistakes to avoid
One of the biggest mistakes I see people make is assuming that all collagen powders are the same. They’re not. Some are basic, containing just Type I and III collagen, while others include added vitamins, probiotics, or multiple collagen types. If you’re looking for a specific benefit—like gut health or joint support—make sure the powder you choose aligns with your goals. Another mistake is ignoring the dissolve rate. I’ve tried powders that clump in cold water or leave a gritty residue, which is frustrating when you’re just trying to get your morning coffee down. Always check reviews for mentions of texture, or opt for a brand known for smooth dissolving, like Vital Proteins. Overlooking the serving size is another common error. Some tubs look large but have tiny serving sizes, meaning you’ll go through them faster than you expect. Always check the number of servings per tub to avoid frequent repurchasing. Finally, don’t assume that more expensive means better. While premium options like Wholesome Wellness’s multi-collagen blend offer more benefits, they’re not necessary if you’re just looking to support your hair and nails. Start with a basic option, like Anthony’s or Vital Proteins’ 9.33oz tub, and see how your body responds before upgrading. And if you’re using collagen alongside other hair care products, like castor oil for hair growth, make sure you’re not overloading your routine—sometimes less is more.
Budget vs premium — is more expensive worth it?
The short answer? It depends. If you’re just looking for a basic collagen powder to support your hair and nails, a budget-friendly option like Anthony’s or Vital Proteins’ 9.33oz tub will do the job. These powders contain Type I and III collagen, which are great for hair, skin, and nails, and they dissolve well in liquids. They’re also unflavored, so you can mix them into anything without altering the taste. The downside? They don’t include any extras, like Vitamin C or probiotics, which can enhance the benefits. Premium options, like Vital Proteins Advanced or Wholesome Wellness’s multi-collagen blend, offer more. The Advanced version includes Vitamin C and hyaluronic acid, which support collagen production and skin hydration. Wholesome Wellness’s blend includes five types of collagen, sourced from beef, chicken, fish, and eggshell membrane, which can support joints, gut health, and more. These options are more expensive, but if you’re looking for a broader range of benefits, they’re worth the investment. The other thing to consider is the tub size. Premium options often come in larger tubs, which can make them more cost-effective in the long run. For example, Vital Proteins’ 20oz Advanced version is more expensive upfront, but it lasts longer than the 9.33oz tub. If you’re not sure whether collagen is right for you, start with a budget-friendly option and see how your body responds. If you notice a difference, you can always upgrade to a premium blend later. And if you’re pairing collagen with other hair care products, like argan oil for frizz control, you’ll see even better results.
Safety + when to ask your doctor
Collagen powders are generally safe for most people, but there are a few things to keep in mind, especially during pregnancy or if you have specific health conditions. First, always check the sourcing. Grass-fed, pasture-raised bovine is the gold standard, as it’s free from hormones and antibiotics. If you have allergies—like to fish, eggs, or chicken—make sure the collagen powder you choose doesn’t contain those ingredients. Some multi-collagen blends, like Wholesome Wellness’s, include collagen from multiple sources, so always read the label. If you’re pregnant or breastfeeding, it’s always a good idea to check with your midwife or doctor before starting any new supplement, including collagen. While collagen is generally considered safe, everyone’s body is different, and it’s important to make sure it’s right for you. If you’re taking other supplements or medications, collagen can interact with them, so it’s worth double-checking. Finally, if you notice any adverse reactions—like digestive issues, skin breakouts, or joint pain—stop taking the collagen and consult your healthcare provider. Collagen powders aren’t a magic solution, and they won’t replace a balanced diet or proper hair care. If you’re dealing with severe hair loss or other health issues, always seek professional advice. And if you’re looking for additional ways to support your hair, products like deep conditioning masks can complement your collagen routine.
How we picked
I tested these six collagen powders over six months, using each one for at least four weeks to assess its effects on my hair, skin, and nails. I mixed them into my daily coffee, smoothies, and even soups to see how they dissolved and whether they altered the taste. I also considered factors like texture, sourcing, added ingredients, and value for money. My goal was to find options that actually fit into a busy parent’s routine—no clumping, no weird aftertastes, and no unnecessary extras. Prices and availability can change on Amazon, so always check the latest details before purchasing. And remember, what works for one person might not work for another, so it’s worth trying a few options to see what your body responds to best.
Frequently asked questions
Does collagen powder really help with hair growth?
Collagen provides the amino acids your body needs to produce keratin, the protein that makes up your hair. While it won’t stop postpartum shedding entirely (that’s largely hormonal), many people notice their hair feels thicker and less brittle after consistent use. It’s not a miracle cure, but it can support overall hair health, especially when paired with other treatments like deep conditioning masks. Results vary, so give it at least 6-8 weeks to see a difference.
Can I take collagen powder during pregnancy?
Collagen is generally considered safe during pregnancy, but it’s always best to check with your midwife or doctor first. Some women prefer to wait until after the first trimester, while others take it throughout. If you’re concerned about sourcing, opt for a grass-fed, pasture-raised option like Vital Proteins or Garden of Life. And remember, collagen isn’t a replacement for a balanced diet—focus on getting nutrients from whole foods first.
How long does it take to see results from collagen powder?
Most people start noticing subtle changes—like stronger nails or less brittle hair—after about 4-6 weeks of consistent use. For more noticeable results, like improved skin elasticity or reduced joint stiffness, it can take 8-12 weeks. Collagen works gradually, so don’t expect overnight miracles. Pairing it with other hair care products, like argan oil for frizz control, can help you see results faster.
Can I mix collagen powder into hot drinks?
Yes! Most collagen powders, like Vital Proteins and Garden of Life, dissolve easily in hot or cold liquids. I mix mine into coffee, tea, and even soups without any issues. The key is to stir it well to avoid clumps. If you’re sensitive to texture, opt for a finely milled powder, as some budget options can be slightly grittier.
Is unflavored collagen powder really tasteless?
Most unflavored collagen powders are very mild, but some people notice a faint earthy or slightly savoury aftertaste, especially if they’re sensitive to flavours. If you’re mixing it into something strongly flavoured, like a fruit smoothie or coffee, you likely won’t notice it. If you’re sensitive to aftertastes, try mixing it into a smoothie with berries or banana to mask any subtle flavours.
Can I take collagen powder if I’m vegetarian or vegan?
No—collagen is derived from animal sources, like bovine, chicken, or fish. If you’re vegetarian or vegan, you can look for plant-based supplements that support collagen production, like silica, Vitamin C, or amino acid blends. These won’t provide collagen directly, but they can help your body produce it naturally. Always check the label to make sure the product is truly vegan.
What’s the difference between hydrolyzed collagen and regular collagen?
Hydrolyzed collagen, also called collagen peptides, has been broken down into smaller molecules, making it easier for your body to absorb. This is why most collagen powders are hydrolyzed—it ensures you’re getting the maximum benefit. Regular collagen, like the kind found in bone broth, is larger and harder for your body to digest. If you’re taking collagen for hair, skin, or joint support, hydrolyzed is the way to go.
The verdict
After six months of testing, I’ve learned that the best collagen powder for hair isn’t necessarily the most expensive or the one with the most bells and whistles. It’s the one that fits seamlessly into your routine and delivers results you can actually see and feel. If you’re new to collagen and just want something simple, Vital Proteins’ 9.33oz tub is a great starting point—it’s affordable, dissolves easily, and does the job without any fuss. If you’re looking for something with added benefits, like Vitamin C or hyaluronic acid, Vital Proteins’ 20oz Advanced version is the best all-in-one option. It’s pricier, but the larger tub lasts longer, and the extras make it worth the investment. For those dealing with gut issues or sensitive stomachs, Garden of Life’s collagen powder is the standout—it includes probiotics and enzymes, which can make a real difference if you’re struggling with digestion during pregnancy or postpartum. And if you’re looking for a broader spectrum of benefits, Wholesome Wellness’s multi-collagen blend is the way to go. It’s the most expensive option, but the variety of collagen types makes it a great choice if you’re also dealing with joint stiffness or want to support your skin’s elasticity. No matter which one you choose, remember that collagen works gradually. Give it at least 6-8 weeks to see results, and pair it with other hair care products, like deep conditioning masks or argan oil for frizz control, for the best outcome. And always check with your midwife or doctor before starting any new supplement, especially during pregnancy or if you have specific health concerns.
