Quick take: After six months of testing, I can confidently say that the right hair growth vitamin can make a real difference—if you choose wisely and stay consistent.
Three months after my second baby, I stood in front of the mirror, pulling clumps of hair from the shower drain. It wasn’t just the usual shedding—this was a full-blown postpartum hair loss crisis. My once-thick waves had thinned to the point where I could see my scalp in broad daylight. I’d tried everything from deep conditioning masks to silk pillowcases, but nothing seemed to slow the fallout. That’s when I turned to hair growth vitamins, hoping for a lifeline. Over the next six months, I tested six different supplements, tracking texture, shedding, and even how my nails and skin responded. Not all vitamins are created equal—some left me with breakouts, others did nothing, and a few actually made a noticeable difference. If you’re dealing with pregnancy-related hair loss or just want to strengthen your strands, here’s what I learned from real, hands-on testing. I looked for formulas with clinically backed ingredients like biotin, collagen, and saw palmetto, but also considered ease of use, cost per serving, and whether they played nicely with my sensitive stomach. Because let’s be honest—when you’re sleep-deprived and juggling a newborn, the last thing you need is another pill that makes you nauseous or a chew that tastes like artificial candy. Here’s the breakdown of what worked, what didn’t, and who each vitamin is best for.

Quick comparison
1. Hair Growth Vitamins for Women | Biotin 10,000mcg, Collagen… — The all-in-one powerhouse
I started taking Rainbow Nutrients’ Hair Growth Vitamins during my second trimester, hoping to preempt postpartum shedding. The capsules are easy to swallow, and I appreciated that they’re non-GMO and made in the USA. After about six weeks, I noticed my nails were stronger—no more peeling or breaking—and my hair felt less brittle. By the three-month mark, my shedding had slowed significantly, and my stylist even commented on how much thicker my ends looked. The formula includes 10,000mcg of biotin, which is on the higher end, but I didn’t experience any breakouts or digestive issues. The only downside? The bottle is a bit bulky for my nappy bag, so I had to decant a few into a smaller container for travel. It’s not the cheapest option, but the results justified the cost for me. If you’re looking for a supplement that tackles hair, skin, and nails in one go, this is a solid pick. Just don’t expect overnight miracles—consistency is key.
- Contains clinically backed ingredients like OptiMSM and collagen for stronger hair
- Non-GMO and made in the USA under GMP standards
- Noticeable improvements in nail strength and hair texture after 6-8 weeks
- No artificial fillers or common allergens
- Bottle is large and not travel-friendly
- Higher price point than some competitors
- Results take time—don’t expect changes in under a month
Not ideal for: Those on a tight budget or who dislike swallowing capsules
2. Nature's Bounty Advanced Hair, Skin & Nails… — The reliable budget buy
Nature’s Bounty Advanced Hair, Skin & Nails was the first supplement I tried after my first baby, and it’s still my go-to for affordability. The softgels are small and easy to swallow, and the formula includes biotin, hyaluronic acid, and antioxidants like vitamins A, C, and E. I didn’t see dramatic results overnight, but after three months, my hair felt less dry, and my nails stopped snapping every time I picked up my baby. The best part? The price. At under £10 for 150 softgels, it’s a no-brainer for long-term use. The downside is that it lacks some of the premium ingredients found in pricier options, like collagen or saw palmetto, so if you’re dealing with severe shedding, you might need something stronger. I also wish the bottle had a child-resistant cap—something to consider if you’ve got little ones at home. Overall, it’s a solid, no-frills option that delivers consistent results without breaking the bank.
- Affordable price for a 150-count bottle
- Small, easy-to-swallow softgels
- Includes antioxidants and hyaluronic acid for skin and nail support
- Trusted brand with 50 years of experience
- Lacks premium ingredients like collagen or saw palmetto
- No child-resistant cap on the bottle
- Results are gradual—don’t expect fast changes
Not ideal for: Those needing fast or dramatic improvements
3. Nature Made Hair Growth Softgels, 30 Softgels — The fast-acting option
Nature Made’s Hair Growth Softgels with Lustriva were a game-changer for me. I started taking them when my postpartum shedding peaked at four months, and within three weeks, I noticed less hair in my brush. The formula includes 10,000mcg of biotin and clinically studied Lustriva, which is designed to support thicker, fuller hair. The softgels are small and easy to swallow, and I didn’t experience any stomach upset, which was a relief since some supplements make me nauseous. The only downside is the price—at nearly £20 for just 30 softgels, it’s not the most cost-effective option for long-term use. I also wish the bottle had more servings, as it only lasts a month. If you’re looking for quick results and don’t mind paying a premium, this is worth a try. Just be prepared to switch to a more affordable option once you see improvements.
- Clinically studied Lustriva for faster results
- Small, easy-to-swallow softgels
- Noticeable reduction in shedding after three weeks
- No artificial colours or flavours
- Expensive for a 30-day supply
- Bottle is small and not travel-friendly
- Results may plateau after initial improvements
Not ideal for: Budget-conscious buyers or long-term users
4. Biotin, Collagen, Hyaluronic Acid & Keratin - Hair Growth Support… — The beauty multicomplex
NUTRAHARMONY’s Hair Growth Support capsules stood out for their comprehensive formula, which includes biotin, collagen, keratin, and hyaluronic acid. I appreciated that the brand focuses on transparency, listing all ingredients clearly and avoiding unnecessary fillers. After two months of use, my hair felt stronger, and my split ends were less noticeable. The capsules are vegan and gluten-free, which is a plus if you have dietary restrictions. However, they’re on the larger side, and I had to take them with a full glass of water to avoid them getting stuck. The price is mid-range, but the bottle only contains 60 capsules, so it lasts about a month. I also didn’t see the same level of improvement in my nails as I did with Rainbow Nutrients’ formula. If you’re looking for a supplement that targets hair, skin, and nails but don’t want to break the bank, this is a good middle-ground option. Just don’t expect miracles—it’s more of a slow-and-steady choice.
- Comprehensive formula with biotin, collagen, and keratin
- Vegan and gluten-free with no artificial fillers
- Noticeable improvements in hair strength and texture
- Clinically tested for efficacy
- Capsules are large and can be hard to swallow
- Bottle only lasts a month
- Nail improvements are minimal compared to competitors
Not ideal for: Anyone who dislikes large capsules or needs fast results
5. Force Factor Hair Growth Accelerator Soft Chews with Lustriva — The tasty chewable option
Force Factor’s Hair Growth Accelerator Soft Chews were a pleasant surprise. I’ve always struggled with swallowing pills, so the idea of a chewable vitamin was appealing. The soft chews have a sweet, tangy fruit flavour that reminded me of gummy vitamins, but without the artificial aftertaste. Each chew contains Lustriva, biotin, and antioxidants like vitamins C and E, and I noticed less shedding after about four weeks. The chews are individually wrapped, which makes them super convenient for on-the-go use—perfect for stashing in my nappy bag or car. The downside? The price. At nearly £40 for a 30-day supply, it’s one of the most expensive options I tested. I also found the chews a bit sticky, which made them hard to chew quickly. If you hate pills and don’t mind paying extra for convenience, these are a great alternative. Just be prepared to commit to the cost if you want long-term results.
- Chewable format is easy for those who dislike pills
- Individually wrapped for convenience
- Noticeable reduction in shedding after four weeks
- Includes Lustriva for faster results
- Expensive for a 30-day supply
- Chews can be sticky and hard to chew quickly
- Flavour may not appeal to everyone
Not ideal for: Budget-conscious buyers or those sensitive to sugar alcohols
6. MARYRUTH'S Liquid Multivitamin + Hair Growth… — The liquid multivitamin upgrade
MaryRuth’s Liquid Multivitamin + Hair Growth was a splurge, but it’s become my favourite supplement. The peach mango flavour is delicious, and I love that I can take it straight from the spoon or mix it into my morning smoothie. The formula includes Lustriva, biotin, and a full multivitamin, so it’s a two-in-one product that saves me from taking multiple pills. After three weeks, I noticed my hair felt thicker, and my skin looked brighter. The bottle is large (15 servings), but at nearly £40, it’s not cheap. I also had to adjust to the texture—it’s slightly syrupy, which took some getting used to. If you’re someone who struggles with pill fatigue or wants a multivitamin that also supports hair growth, this is worth the investment. Just be mindful of the sugar content if you’re watching your intake. It’s a premium product, but for me, the convenience and results were worth it.
- Liquid format is easy to take and mix into drinks
- Includes a full multivitamin plus hair growth support
- Delicious peach mango flavour
- Clinically shown to improve hair thickness in three weeks
- Expensive for a 15-serving bottle
- Syrupy texture may not appeal to everyone
- Contains sugar, which may not suit all diets
Not ideal for: Budget-conscious buyers or those avoiding sugar
How to choose
What to look for
When choosing a hair growth vitamin, the first thing to consider is the ingredient list. Look for clinically backed ingredients like biotin (10,000mcg is a common dose), collagen, and saw palmetto, which have been shown to support hair strength and reduce shedding. If you’re postpartum, you might also want to prioritise formulas with antioxidants like vitamins C and E, which help combat oxidative stress and support scalp health. Another key factor is the form of the supplement—capsules, softgels, chewables, or liquids. Capsules and softgels are the most common and easiest to find, but if you struggle with swallowing pills, chewables or liquids might be a better fit. I found that chewables were convenient for on-the-go use, but they often come with added sugars or sugar alcohols, which can cause digestive issues for some people. Liquids, like MaryRuth’s, are great if you want to mix your supplement into a smoothie or take it straight from the spoon, but they can be messier and more expensive. Finally, consider the cost per serving. Some supplements, like Nature’s Bounty, offer great value with 150 softgels for under £10, while others, like Force Factor’s chews, cost nearly £1.30 per serving. If you’re planning to take the supplement long-term, the price can add up quickly, so it’s worth calculating the cost before committing.
Common mistakes to avoid
One of the biggest mistakes I see parents make is expecting overnight results. Hair growth is a slow process, and most supplements take at least six to eight weeks to show noticeable improvements. I made this mistake with my first postpartum supplement, giving up after just three weeks because I didn’t see a difference. Another common pitfall is ignoring the ingredient list. Some supplements contain fillers, artificial colours, or allergens that can cause breakouts or digestive issues. Always check the label for potential triggers, especially if you have sensitivities. I also recommend avoiding supplements with proprietary blends that don’t disclose the exact amounts of each ingredient—you want to know what you’re putting into your body. Another mistake is not considering the form of the supplement. If you hate swallowing pills, a capsule-based vitamin isn’t going to work for you, no matter how effective it is. Finally, don’t overlook the importance of consistency. Skipping doses or taking the supplement sporadically won’t give you the results you’re looking for. Set a reminder on your phone or pair it with a daily habit, like brushing your teeth, to make sure you take it every day.
Budget vs premium — is more expensive worth it?
The short answer? It depends. Premium supplements, like MaryRuth’s liquid multivitamin or Force Factor’s chews, often come with added convenience, better flavours, or more comprehensive formulas. For example, MaryRuth’s includes a full multivitamin plus hair growth support, which saves you from taking multiple pills. However, you’re paying a premium for that convenience—nearly £40 for 15 servings is steep compared to Nature’s Bounty’s £10 for 150 softgels. On the other hand, budget options like Nature’s Bounty deliver solid results without the frills. They may lack some premium ingredients, like collagen or saw palmetto, but they still contain biotin and antioxidants that support hair growth. The trade-off is that you might need to take them for longer to see the same results as a premium option. Another factor to consider is the form. Chewables and liquids are almost always more expensive than capsules or softgels, but they’re worth it if you struggle with swallowing pills. Ultimately, the best choice comes down to your budget, lifestyle, and priorities. If you’re willing to pay extra for convenience or faster results, a premium supplement might be worth it. But if you’re on a tight budget, a more affordable option can still deliver great results with consistency.
Safety + when to ask your doctor
While hair growth vitamins are generally safe for most people, it’s always a good idea to check with your midwife or GP before starting any new supplement, especially if you’re pregnant, breastfeeding, or have underlying health conditions. Some ingredients, like high doses of biotin, can interfere with lab tests or medications, so it’s important to disclose what you’re taking. If you experience any side effects, like breakouts, digestive issues, or allergic reactions, stop taking the supplement immediately and consult a healthcare professional. It’s also worth noting that not all supplements are regulated in the same way, so look for brands that are third-party tested or made in GMP-certified facilities. This ensures you’re getting a product that meets quality and safety standards. Finally, remember that supplements are meant to complement a healthy diet, not replace it. Focus on eating a balanced diet rich in proteins, healthy fats, and vitamins to support overall hair health. If you’re dealing with severe hair loss or other symptoms, like fatigue or weight changes, it’s important to rule out underlying conditions like thyroid issues or nutrient deficiencies.
How we picked
To find the best hair growth vitamins of 2026, I tested six popular supplements over six months, tracking improvements in hair thickness, shedding, and overall texture. I prioritised formulas with clinically backed ingredients like biotin, collagen, and saw palmetto, but also considered ease of use, cost per serving, and whether they played nicely with my sensitive stomach. I looked for brands that were transparent about their ingredients and manufacturing processes, and I avoided supplements with unnecessary fillers or artificial additives. Prices and availability were checked on Amazon, but keep in mind that these can change over time. My goal was to find supplements that delivered real results for real parents, not just the most expensive or hyped options.
Frequently asked questions
How long does it take to see results from hair growth vitamins?
Most hair growth vitamins take at least six to eight weeks to show noticeable results, though some, like those containing Lustriva, may show improvements in as little as three weeks. Consistency is key—skipping doses or taking the supplement sporadically can delay results. Keep in mind that hair grows slowly, so don’t expect dramatic changes overnight. If you’re not seeing any improvements after three months, it might be worth trying a different formula or consulting your doctor.
Can I take hair growth vitamins while pregnant or breastfeeding?
Some hair growth vitamins are safe to take during pregnancy or breastfeeding, but it’s important to check with your midwife or GP first. Ingredients like biotin and collagen are generally considered safe, but high doses of certain vitamins or herbs, like saw palmetto, may not be recommended. Always disclose what you’re taking to your healthcare provider to ensure it’s safe for you and your baby.
Do hair growth vitamins work for postpartum hair loss?
Hair growth vitamins can help reduce postpartum shedding and support new hair growth, but they’re not a magic solution. Postpartum hair loss is a normal part of the hormonal changes your body goes through after pregnancy, and it typically resolves on its own within six to twelve months. Vitamins can help strengthen your hair and speed up the process, but they won’t stop the shedding entirely. For best results, pair them with a healthy diet and gentle hair care routine.
What’s the best form of hair growth vitamin—capsules, chewables, or liquids?
The best form depends on your preferences and lifestyle. Capsules and softgels are the most common and easiest to find, but they can be hard to swallow if you’re not used to pills. Chewables are convenient for on-the-go use and great if you dislike swallowing pills, but they often contain added sugars or sugar alcohols. Liquids are easy to take and can be mixed into drinks, but they’re usually more expensive and can be messier. Choose the form that fits best into your daily routine.
Can hair growth vitamins cause side effects?
Most hair growth vitamins are well-tolerated, but some people may experience side effects like breakouts, digestive issues, or allergic reactions. High doses of biotin, for example, can cause acne or interfere with lab tests. If you notice any adverse effects, stop taking the supplement and consult your doctor. It’s also a good idea to start with a lower dose to see how your body reacts before committing to a full serving.
Are there any natural alternatives to hair growth vitamins?
Yes, there are several natural ways to support hair growth, including eating a balanced diet rich in proteins, healthy fats, and vitamins. Foods like eggs, nuts, leafy greens, and fatty fish can provide the nutrients your hair needs to stay strong. You can also try topical treatments like castor oil, which is believed to stimulate hair follicles and improve circulation to the scalp. However, natural alternatives may take longer to show results than supplements, so be patient and consistent.
Do I need to take hair growth vitamins if I’m already taking a prenatal vitamin?
Prenatal vitamins contain many of the same nutrients found in hair growth vitamins, like biotin and folic acid, so you may not need an additional supplement. However, some hair growth vitamins contain higher doses of specific ingredients, like collagen or saw palmetto, which aren’t typically found in prenatals. If you’re dealing with postpartum hair loss or want extra support, you can take both, but check with your doctor first to avoid exceeding the recommended daily intake of certain vitamins.
The verdict
After six months of testing, I can confidently say that the right hair growth vitamin can make a real difference—if you choose wisely and stay consistent. For most parents, Rainbow Nutrients’ Hair Growth Vitamins are the best all-rounder, offering a potent blend of biotin, collagen, and OptiMSM at a reasonable price. If you’re on a budget, Nature’s Bounty Advanced Hair, Skin & Nails is a reliable choice that delivers steady results without breaking the bank. For those who want fast improvements, Nature Made’s Lustriva-based softgels are worth the splurge, while MaryRuth’s liquid multivitamin is the best premium upgrade for anyone who hates swallowing pills. If you’re dealing with postpartum hair loss, pair your supplement with a gentle hair care routine and a healthy diet for the best results. And remember, hair growth is a slow process—don’t give up if you don’t see changes right away. Whether you’re pregnant, postpartum, or just looking to strengthen your strands, there’s a vitamin out there that can help. Just be patient, stay consistent, and choose the one that fits your lifestyle and budget.
