Hairprin Reviews

As Good As Folexin?

The Science of Hairprin

If you’ve followed Lady Alopecia for a while, you’ll know that I’m leaning more and more towards a holistic route these days in order to treat hair loss and promote hair growth. Because things like our gut microbiome, our stress levels and our hormones are such common triggers of hair loss, it makes sense to use full-body wellness as a treatment plan, rather than just using topical treatments for the scalp.

While I appreciate that not everyone should or needs to take a supplement, may of us do have nutritional deficiencies or hormonal imbalances that require a little extra help. And the right daily supplement can work wonders in supporting the immune system and giving the body the energy it needs for metabolic functions – like hair growth.

Thing is, when we’re run down, or we’ve been sick, or we’re going through a big transition, often the first thing to shut down is this basic function. So we get stuck in the ‘resting’ or telogen phase of the hair growth cycle and need something to kickstart the ‘growth’ or anagen phase again.

A good supplement serves to do exactly that. And from what I’ve read in Hairprin Reviews, it seems like it contains all the right ingredients to help those with thinning hair or hair loss, start to claim their locks back.

What is Hairprin? Brand & Background

Hairprin are a range of hair loss supplements scientifically formulated to stop chronic hair loss, fast – and to promote rapid regrowth. Well, that’s what it promises on Approved Science’s website, the brand behind Hairprin.

The company’s team of top medical doctors created Hairprin with the aim of improving individual health and wellbeing: getting to the root cause of hair loss and chronic thinning rather than just addressing the short-term symptom. With their range of supplements, they hope to bring more energy, vitality and strength back to people’s lives.

Big claims but are Hairprin to be trusted? Well, signs look positive. The hair vitamins are produced in a cGMP certified and FDA registered laboratory by medical experts. Each ingredient undergoes extensive scientific research and testing before being selected and the dosages of each ingredient are clinically tested too, for the best results.

This sets Hairprin apart from many other hair vitamins, which just seem to pack everything in with little thought given to the recommended dose of each ingredient. Not only should this make Hairprin more effective, but safer to consume, too.

Approved Science produce over a dozen different supplements, each of which is designed to target a specific issue: but for the purpose of this Hairprin review, I’ll be focusing on the supplements that aim to stimulate the scalp, unblock and rejuvenate hair follicles, stop and prevent hair loss and rapidly restore hair growth.

Approved Science In 4 Steps

So how does Hairprin achieve all of these great benefits? Well, it’s all in the design and the delivery. Approved Science don’t just throw any ol’ ingredients in: they’re dedicated to formulating the best possible combination of ingredients, and making sure they work together in the right way.

Here’s the 4-step process they use to create Hairprin hair supplements.

  • Research: A team of experts conducts extensive research and clinical studies to test the effectiveness of each hair growth ingredient – and, importantly, the dosage required for maximum and safe absorption.
  • Review: Based on the results of the clinical studies, each ingredient is carefully reviewed. Only the best will make it to the third round!
  • Creation: These ingredients are combined in their recommended dosages to formulate Hairprin supplements
  • Customer Service: The final step is to guarantee the quality of these products…and if people aren’t happy, well they have a return policy where you can return unopened or bottles within 60 days and get your money back (but you need to cover return shipping costs). They also have team of health advice experts you can contact for support.

Ingredients & Benefits

Although Hairprin include some pretty great ingredients, ones that have been proven in clinical trials to promote hair growth and tackle hair thinning, it’s not just what’s inside that counts. It’s how much is inside, too. Just like WellBel, another popular holistic brand, Hairprin pays particular attention to the potency required for the best hair results.

The vegan hair vitamins are also free from fillers, additives, preservatives, binders or other artificial ingredients. Good to know.

Next up, the impressive list of active ingredients – and what they mean for healthy hair.

  • Saw Palmetto Extract: Clinically proven as a natural DHT blocker that can improve hair density and quality in those suffering from multiple forms of hair loss, including telogen effluvium and androgenetic alopecia (male pattern hair loss).
  • Ginkgo Biloba: A vasodilatory rich in flavanoids, it acts as an antioxidant to gently cleanse the scalp, soothe irritation, fight damage from free radicals and widen blood vessels to boost circulation to the scalp
  • Fo-Ti: Also known as Fallopia Multiflora, this Chinese plant is in top hair supplement Folexin. It promotes melanin production to support the hair growth process and retain your hair’s natural color, while helping your cells get rid of toxins.
  • Vitamin A: Contributes to stronger and thicker locks – adding shine, reducing shedding and improving growth.
  • Vitamin E: Has antioxidative effects that protects the hair from free radical and damage and reduces oxidative stress in the body.
  • Vitamin B Complex (B2, B5, B6 & B12): Supports healthy cell rejuvenation through assisting in the production of red blood cells (which naturally support your hair follicles). Great for energy and brain health, too!
  • Zinc: Supports metabolic function to strengthen hair follicles. Also reduces dandruff and balances hormones to improve hair growth.
  • Iron: Iron deficiency is common for those with hair loss (especially women). Also, older populations may find iron difficult to absorb from food – so a supplement could be useful.
  • Copper: Helps to enlargen hair follicles, making it easier for new hair growth.
  • Folic Acid: The CDC (Center of Disease Control) actually recommend taking 400 mcg of folic acid daily to help with hair follicle production and to produce healthy, full hair.
  • Selenium: An amino acid that has an antioxidant effect and supports the production of hair proteins.
  • Iodine: Tackles hormone-related hair loss, particularly those affected by thyroid imbalances.
  • Methylsulfonylmethane (MSM): Contains sulfur, which plays an important role in joint and soft tissue health. MSM is also a potent anti-oxidant and an anti-inflammatory.
  • L-Methionine: Another antioxidant amino acid that contains sulfur to reduce hair loss, slow down greying of hair, strengthen hair structure by promoting collagen production and add shine/smoothness.
  • L-Cysteine: This amino acid is one of the key players in building keratin, an important hair protein that provides strength and elasticity to hair. It’s also an antioxidant that fights free radical damage, promoting natural hair growth and hair restoration.
  • Silica: Supports collagen production, improves hair texture and prevents breakage.
  • Borage: A plant that’s rich in Omega-6 fatty acids to moisturize and nourish your hair and scalp, while reducing inflammation and irritation.

Whew, that’s a lot of ingredients, right?! But they’ve all been tested to check for their effectiveness and come out tops. Approved Science also focus on the best methods to combine these ingredients, which we’ll look at in the next section.

Does Hairprin Really Work? Science Bit

Like Nioxin, another top hair thinning brand, these guys are a fan of processes and steps! Their first step towards promoting hair growth is Control.

The supplements include saw palmetto and iodine to address any nutritional deficiencies that could be triggering your hair loss and also to block DHT – the hormone most commonly linked to hair loss, particularly androgenetic alopecia (or male pattern baldness). In doing so, they can control and slow down the rate of shedding.

The second step is Stimulation. This is a key step because, if you’ve got dormant hair follicles or you’re in an extended telogen (resting) phase of the hair growth cycle, you likely need an extra boost to move into the anagen (growth) phase. Topical stimulants like a good caffeine shampoo can help things along, as can Hairprin’s ingredients like ginkgo biloba and copper: which boost blood flow to the scalp and ensure it gets key nutrients quicker.

Third up, is Hair Restoration. Hairprin can treat and repair damaged hair (from heat styling, color treatments or environmental factors) with essential vitamins and amino acids that nourish the scalp, increase folicular growth and support healthy hair follicles. And a healthy scalp environment means healthy hair can take root.

Finally, the fourth step is Prevent. (Although maybe this makes more sense as the first step? Hmmm…) Anyway, all those lovely sulfur-based amino acids work to strengthen the hair, reduce scalp inflammation, clear excess build-up and prevent the kind of factors that can lead to hair loss in the first place. Yay!

Customer Reviews

Despite all those great ingredients, and Approved Science’s big claims of rapid hair growth, the customer reviews – on Amazon, anyway – don’t really match up. These hair vitamins only get 3.7 stars out of 435 reviews, which is FAR less than competitors like Viviscal (which gets 4.4 out of almost 6.5K reviews).

But the positive reviews mention that it does take time (halfway through the second bottle to start seeing results and not until the third bottle, or Month 3 for best results) – so if you do try Hairprin, don’t give up if you don’t notice any changes after the first month!

The negative reviews aren’t actually that negative – but they complain about the fishy smell and taste of the pills. A couple of reviewers also complain about Approved Science’s customer service, too…that they never got the refund they were guaranteed.

I believe the product is working and have decided to continue taking it. In three months time I see a significant difference in my hair. I no longer see as much scalp in my part and there is a lot of new growth. My hair had gotten pretty thin do to health issues and stress and I realize it is going to take time to recover. I never thought my hair would look better and I am very happy to see the positive changes.

– Babs, US

I have a thyroid disorder and awhile back I noticed my hair was thinning. Now my hair feels thick and full! When I first started using it I didn’t tell my hairdresser After 3 months she asked me what I was doing different because my hair felt thicker! I have been taking this product for YEARS and love it! My husband was starting to lose his hair and he started taking it as well. His hair is much thicker. Don’t mistake that for his hair grew back. It didn’t. It is truly looks and feels thicker.

I had an issue, therefore was unable to use the product. Needed to return the remainder of the order. So I returned as advised, BUT, they are claiming it was never returned, so therefore I’m not pleased.

Side Effects & Contraindications

All hair loss treatments, whether they’re natural or chemical-heavy, topical treatments or hair vitamins, come with potential side effects. After all, we’re all different and could have different reactions to even plant-based ingredients.

Plus, some people might have sensitive skin, sensitive stomachs, or have excess stores of minerals like biotin or zinc in their body (in which case, they shouldn’t take a supplement that contains these ingredients). I would also check with your doctor before taking extra copper, just to check any toxicity issues.

In general, Hairprin supplements are considered safe to use. But be aware of these potential side effects and discontinue use if they arise for you:

  • Nausea (possibly due to the overpowering smell/taste)
  • Headaches
  • Mild dizziness

If you’re pregnant or breastfeeding, it’s probably best to avoid taking hair supplements that haven’t been approved by your doctor. And since these hair vitamins contain Vitamin A, they aren’t recommended during pregnancy anyway. Also, avoid if you’re taking blood thinners or have heart issues or diabetes.

Hairprin Pros & Cons

Pros of Hairprin

  • No fillers or additives
  • Proven natural hair growth promotors
  • Minimal side effects
  • Helps tackle hormone-related hair loss
  • Great for nutritional deficiencies


  • Moderately expensive
  • Off-putting smell, bad aftertaste
  • Large pills to swallow
  • Not suitable for pregnancy
  • Toxicity concerns (copper, iron, zinc)
  • Clinical study results not made available

Alternatives: Folexin and Viviscal

I’ve mentioned these 2 popular hair vitamins in this post already and, in my opinion, both of them are better options than Hairprin.

About Viviscal

Viviscal has the lowest dosage of biotin than any other hair supplement – so it’s safe to use even if you have a biotin sensitivity. It’s backed by celebrities and dematologists alike, it’s slightly cheaper than Hairprin and, perhaps most importantly, it has published the results of its clinical trials on its website.

Hairprin, on the other hand, keeps saying it has scientific evidence behind it…but where are those studies? Sure, there are studies available on its key ingredients and how they help hair growth…but I couldn’t find any on the actual hair vitamins themselves.

Viviscal have a great reputation in the supplement industry and as well as their hair supplements (available for both men and women) they have a range of great and affordable haircare products you can use, too. Note: the pills also have a fishy taste and smell though, due to the marine proteins they include. So that might put you off.

About Folexin

Again, Folexin has had more published studies completed on its active ingredients. Folexin is more gentle on your stomach than either Hairprin or Viviscal, with a neutral taste – I couldn’t find any negative side effects associated with these pills..

Many Lady Alopecia readers have written to me about their wonderful hair growth results and improved energy after using Folexin for a few months. And unlike Approved Science, people are really positive about the brand’s customer service.

Finally, Folexin is half the price of Hairprin, and it’s cheaper than Viviscal too. So if you’re new to hair vitamins, Folexin could be a great place to start.

Common Questions

Where can I buy Hairprin?

You can buy these supplements from the Approved Science website, or though Amazon. There are great deals available if you buy a few bottles at a time but still, even if you only buy one bottle of Hairprin, it’s not that expensive compared to big brands like Nutrafol. In my opinion though, Folexin is still the best in terms of value!

How much does it cost?

For a single bottle on Amazon, Hairprin costs $49.95. But you can get a 3-pack for $95, which is much better value!

How do I use Hairprin?

Take 2 pills a day: the first should be 30 minutes before breakfast and your second Hairprin pill should be 30 minutes before dinner.

Final Thoughts: It’s a “hmmm” for Hairprin

Honestly, I’m not sure about the effectiveness of these hair vitamins. I mean, on paper they sound great and I love the ingredients they contain. It’s the big claims they make on their website, with no published clinical trials available, that make me take pause.

Still, if you look at these hair vitamins as a way to improve overall hair growth, to reduce shedding and to stimulate blood flow to the scalp rather than expecting a miracle cure, they could be a great option.

In any case, they can improve your skin and nails’ health while giving you more energy…so there’s no harm in trying them out!

So my caveat is this: don’t expect your hair loss to clear up immedietely. But, if you can afford to keep taking these supplements, and can stomach the taste, give them at least 3 months to do their thing. Then make sure to report back here and comment below with your findings!
