25 Best hair growth serums in 2023

Maybe your hair is not as long or thick as you’d like it to be. There are many products out there to increase your hair’s volume, strength, and length. It can feel daunting and confusing to try and pick the product that will work for you. In our experience, serums work the best to add fortification to the hair, healing it and allowing it to grow naturally. That’s why we have rounded up 25 of the best hair growth serums in 2023 for you.

1. Blu Atlas Hair & Body Oil

Blu Atlas has some of the best offerings for hair and skin care. Unlike other brands, Blu Atlas uses clean, vegan ingredients like saw palmetto oil, argan oil, and sweet almond oil.

Saw palmetto’s anti-inflammatory properties fight against hair loss; it also adds hydration and volume to the scalp. Argan oil distributes vitamin E, fatty acids, and antioxidants throughout the scalp to boost damaged hair and reduce frizz. And sweet almond oil protects the hair against damaging UV radiation.

Use daily for the best results and be amazed by the power of Blu Atlas.

2. The Ordinary Multi-Peptide Serum for Hair Density

The Ordinary has quickly become one of the crowd favorites in skincare and haircare fandom over the last few years, and it is no surprise why that is. The Ordinary makes great, simple products that are easy to use (no weird and convoluted steps in their application to get an effective result), have clinically proven ingredients, and offer an amazing bang for your buck. We think the best product from The Ordinary to get your feet wet in what they have to offer is their Multi-Peptide Serum for Hair Density.

This concentrated, lightwright serum uses a vegan, alcohol-free and fragrance-free solution that is designed to promote a noticeable change in hair thickness, density, fullness, and healthier looking hair after the first few applications. Great for all skin types due to its balanced pH of 4.75 to 5.75, Just apply a few drops at bedtime and let The Ordinary do their thing.

3. Grow Gorgeous Intense Hair Density Serum

Grow Gorgeous is the equivalent of an “indie darling” in the haircare space. They seemingly developed a grassroots cult following overnight thanks to their products dedicated to hair growth (which is basically all of them). The fan favorite, and bestseller, is the Grow Gorgeous Intense Hair Density Serum. So, what makes Grow Gorgeous stick out from the competition?

Since hair growth is Grow Gorgeous’s bread and butter, they can focus their efforts entirely on creating products that are formulated purely for hair growth. Their Intense Hair Density Serum represents their best efforts. Starting with the base of their Original Hair Density Serum, the Intense has an advanced concentration to increase the thickness of each strand by up 13 percent while also adding to the number of overall strands.

4. Divi Scalp Serum

The bottle for the next one may look unassuming, but don’t judge one of the best hair growth serums by its packaging. Divi Scalp Serum is a lightweight serum crafted with a resilient blend of various amino acids and peptides that are formulated to help detox follicle buildup, support thicker hair, and promote better scalp health. Overall, these three important tasks, once completed, are the key to encouraging hair to grow back faster and fuller.

The standout ingredient used in Divi Scalp Serum, copper tripeptide-1, has been shown to extend the growth phase and promote thicker-looking hair in clinical trials. While haircare hallmarks like peppermint oil, green tea leaf extract, tea tree oil, and menthol all work to soothe the scalp, remove product and dead skin build-up, stimulate blood circulation, and increase hair density.

5. Virtue Flourish Healthy Hair Growth Density Booster

We’re calling it now, keratin will be the next big thing in haircare by the end of the decade. It’ll be what hyaluronic acid was to skincare in the 2010s. But what is it that makes keratin so different from the rest of the ingredients usually found in haircare, and why is it so rare? Keratin is a family of fibrous proteins found in both plant and animal life. Alpha-keratin, which is found in vertebrates (that’s you, Fritz the hippo, and even your dog), is the organic renewable polymer that is the structural backbone to hair, nail, and skin growth throughout your body.

Up until only recently, alpha-keratin wasn’t available as something you could buy in stores. As the type of keratin made by your body, it took a breakthrough in regenerative medicine to reproduce it through laboratory experiments and clinical tests. Now, it is utilized by pioneering keratin hair care brands, like Virtue, in their Flourish Healthy Hair Growth Density Booster. With just one product, you can finally combat mild to moderate hair loss by using what your body is failing to produce in excess.

6. Ouai Scalp Serum

Ouai has quickly become one of our favorite brands due to their clinically proven products that are crafted with simple, safe, and effective ingredients which are backed by consumer studies. Ouai knows that the key to healthy hair begins at the scalp. That’s why their skincare-inspired Scalp Serum is formulated to balance and hydrate your scalp to create a more supportive environment that is better suited for hair growth.

This serum is crafted with adaptogens and hyaluronic acid to quench your moisture-thirsty scalp, while peptides support the appearance of fuller, thicker, and healthier hair. Also infused in Ouai’s skincare-inspired serum is red clover flower extract, which is known for its ability to reduce scalp discomfort from styling.

7. Derma E Tea Tree Oil Scalp Relief Treatment

You see “dermatologist recommended” on slews of skincare products ranging from drug store royalty like CeraVe and Cetaphil to even plastered on high-end treatments sold at Ulta or Sephora. But rarely do we ever come across haircare products that share the same ringing endorsement as their skincare comrades. Anyway, that was the story up until Derma E stepped onto the personal care scene.

Virtually all of Derma E’s haircare products share the same dermatologist-recommended seal of approval. Why, you may ask? Because Derma E uses the science-proven logic that hair health begins at the scalp. This science-backed reasoning is best on display with their Tea Tree Oil Scalp Relief Treatment which is a water-based serum formulated to soothe and nourish dry, itchy scalp in exchange for a more balanced, and moisturized one more tuned for hair growth.

8. Grande Cosmetics GrandeHAIR Enhancing Serum

Sometimes, the finer things in life don’t come cheap, and who are we to argue when the big bucks bring even bigger results? If you have a hole burning in your wallet and are looking for a quick and easy way to spend $125 before shipping and tax, then look no further than Grande Cosmetics GrandeHAIR Enhancing Serum. Sorry in advance to all the fans and stans, but no relation to that Grande.

Grande Cosmetics started in 2008 as a one-woman operation selling an eyelash-enhancing serum out of her bedroom. She was doing eCommerce before Squarespace and Shopify took off, so that’s an accomplishment in itself. Nevertheless, it shows that there is some history leading up to GrandeHAIR Enhancing Serum, and not all success stories happen overnight—the same applies to hair growth. This serum creates fuller and healthier-looking hair after the first few uses, but only those that stick with it for daily use can reap the rewards of denser, longer hair.

9. Joico Defy Damage Protective Shield

This may not be what you were expecting to see on a list for the best hair growth serums, but hear us out before you scroll past or click off. As we covered above, haircare truly begins at the scalp, and you first must have a healthy scalp before you can have healthy hair. However, the second most important thing in hair care is protecting what you already have.

If your hair takes longer to grow than others, and even when it does finally grow, it grows thinner, then protecting it should be higher on your priority list. Joico Defy Damage Protective Shield can help you with just that. This serum shields your hair from what does it the most harm: thermal styling, UV exposure, and pollution. Additionally, it also works to prevent breakage, color fade, and dryness.

10. Pacifica Scalp Love Rosemary Mint Serum

Pacifica is a brand that hopefully needs no introduction, but for the uninitiated, Pacifica was one of the few select brands that were able to break through into the mainstream and introduce 100% vegan and cruelty-free products to the masses. What’s even more impressive is that they’re still around to tell the tale, making their products in the same way that made them famous. And thankfully for you, and everyone else, they have a serum tailormade to what your dry scalp is craving.

Pacifica’s Scalp Love Rosemary Mint Serum purifies and revives dry scalp with a heavenly blend of rosemary, witch hazel, sage, and thyme. Together, these herbal extracts help detox and loosen buildup while soothing your scalp and keeping it hydrated. What makes this serum even better is that it comes in a glass bottle instead of plastic.

11. Keranique Follicle Boosting Serum

We bet you figured that wasn’t the last you’d be seeing from keratin up above. Not only is it the in thing right now, it also hands down one of the best things you can get for your hair. But chances are that finding the right keratin product for you is easier said than done.

With a name like Keranique, one could assume that this is a brand solely built around using keratin as the base in all their products, and they’d be 100% right. Keranique developed their own keratin amino complex that is fine tuned to strengthen, fortify, and add thickness to thinning hair. This amazing scientific cocktail is on full display in their Follicle Boosting Serum. This serum sends Keranique’s proprietary keratin blend on a mission to nourish each hair follicle to promote stronger, thicker, and fuller hair.

12. Bondi Boost Rapid Repair Serum

Some of the best skin care, especially sunscreen, hails from Australia. And when you think about it, that makes perfect sense. How else are Aussies going to protect their skin from the harsh elements, whether it be the Outback or the Bondi Beach sun, if not for top-of-the-line skincare? However, your skin isn’t the only thing you need to protect.

If you’ve only worried about protecting your skin, and not your hair, don’t fret because you’re definitely not the only one. Although it may be damaged, your luscious locks are not a lost cause. Australian-made Bondi Boost Rapid Repair Serum is a highly concentrated non-sticky and non-greasy serum formulated with clean and vegan-friendly ingredients that seals the hair cuticle and repairs split ends up to 90 percent from its first use.

13. Briogeo Scalp Revival Charcoal + Tea Tree Scalp Treatment Serum

If you haven’t tried any products from the award-winning hair care brand, Briogeo, it’s not too late to jump on the bandwagon. Briogeo uses clinical results to develop the formulations behind all of their products. So, by the time any of their products make it to you, you can breathe easy knowing it went through a ringer of rigorous and thorough testing before hitting store shelves.

Briogeo Scalp Revival Charcoal + Tea Tree Scalp Treatment Serum is a standout from the brand. This soothing and detoxifying scalp treatment was shown to increase scalp hydration by up to 142% and reduce dry scalp flaking by up to 98% in a clinical study with expert clinician evaluation. Hard to argue with those results.

14. Curlsmith Scalp Stimulating Booster

If you have curly hair, then you know how hard it is to find products formulated for those curly strands. What makes it even harder for the curly headed to find a product made for them, is when they’re afflicted with a bad scalp that hurts hair growth. Thankfully, brands like Curlsmith exist to alleviate the struggles those with curls face on the daily.

Like all of Curlsmith products, their Scalp Stimulating Booster is formulated for all types of curls with any type of texture. This daily scalp serum is like skincare for your scalp, and works to create a healthy environment for your hair follicles to grow healthier, fuller, thicker, longer-looking hair.

15. Klorane Strengthening Serum with Quinine and Edelweiss

There are usually two types of hair loss in men and women. It is either hereditary, meaning you can blame your parents’ genetics for it, or it is reactionary which is usually due to stress. If you’re unlucky enough to deal with both of these at the same time, then finding a product that treats both is every part of impossible. Most people resort to using multiple products, but what if it doesn’t have to be that way?

Klorane Strengthening Serum is formulated with quinine bark extract and organic edelweiss, two ingredients shown to treat hereditary and reactional hair loss in both men and women. Together, along with manganese, vitamin B complex, and caffeine, these ingredients also help slow down hair fall, strengthen hair at the root, and stimulate the scalp.

16. VEGAMOUR GRO Hair Serum

Vegan haircare and skincare products are all the rage nowadays. Even household name brands have even capitalized on the vegan hype train. Either by releasing vegan lines of their already existing products, or by creating (or buying up) new brands that focus entirely on vegan products. More vegan products on the market is never a bad thing, right?

Now, for those a little bit savvier when it comes to reading between the lines on big name brand product marketing, might see this vegan hype as a type of greenwashing. However, there are still some new brands out there without all that baggage. Vegamour Gro Hair Serum is a 100 percent vegan formula that uses botanical extracts to help visibly increase hair density up to 50 percent. Shop small next time you’re in the market for a vegan product.

17. Viviscal Gorgeous Growth Densifying Leave-in Elixir

Viviscal Gorgeous Growth Densifying Leave-in Elixir is a lightweight treatment designed to create thicker looking hair. If a voluminous body is what you’re looking for in a hair growth serum, then this leave-in overnight treatment is for you. And if that doesn’t sell you, it is formulated with not just keratin, but also biotin and zinc to create a powerhouse of a serum.

All hair and scalp types can benefit from Viviscal’s sleeper hit (pun intended). Just apply to wet or dry hair before bed and let the serum work its magic. Then wake up to clean, non-greasy hair that will get thicker looking with each application.

18. Luseta Biotin Hair Growth Serum

Luseta has become a crowd favorite in the haircare space for their affordable, effective, and wonderfully formulated hair oils. What is a shame though is that their serums don’t get nearly as much love as they deserve. Although oils and serums provide your hair with the same treatment, those with already oily hair may want a less oily serum like Luseta Biotin Hair Growth Serum.

This natural inspired serum is infused with biotin and collagen that work together to stimulate the scalp to create an encouraging environment for hair growth that nourishes hair to allow for healthier and thicker looking hair.

19. ProBliva Rice Water Spray

Although not a serum, it felt unfair to not mention the ProBliva Rice Water Spray. This spray, just like the serums on this list, is formulated to provide a maximum strength hair growth treatment to your thinning strands. Best part? It couldn’t be easier to apply.

Just spray on your scalp daily to give your scalp what it needs to stay hydrated and effective in its battle to promote hair growth. This spray is for all hair types, is cruelty-free, and vegan-friendly.

20. BOLDIFY Hair Boost Serum

Not every product on the market is suitable to all skin and hair types. If you’re sensitive to medicinal hair growth treatments that use hormonal growth supplements, or react poorly to super high intensity ingredients like minoxidil and other pharmaceuticals, then BOLDIFY has your back (or in this case, scalp) with their Hair Boost Serum.

This serum is crafted with hair friendly ingredients like biotin, collagen, castor oil, rosemary oil, grapeseed oil, saw palmetto, and more that are clinically proven to revitalize the scalp and visibly lengthen hair. In just a few weeks, you’ll notice a denser appearance in your hair as well as a healthy shine.

21. Nutrafol Growth Activator Hair Serum

Nutrafol is back with a new look for their products in 2023. New packaging and bottles are more eco-conscious, but still contain the same effective solutions. If you yet aren’t aware of the brand, we think the perfect introduction would be their dermatologist recommended Growth Activator Hair Serum.

This extremely fast-absorbing and lightweight hair serum is infused with ashwagandha exosomes that boost cell renewal at the scalp. A revitalized scalp helps combat dry, brittle, and thinning hair as well preventing breakage. Plant extracts also nourish and strengthen your strands from their roots to their ends.

22. Lanmeri Vegan Hair Growth Serum

A lot of hair care brands use ingredients that are readily available and present in the majority of mass market products. If you go to the supermarket or drugstore, there is almost a non zero chance that you’ll come across a truly unique product that doesn’t share at least one ingredient with another. It is unavoidable. So, how do brands make their products stick out?

The answer? Proprietary blends. A specific formula using a patented formulation basically means that brand has the sole rights to use it—meaning that no one else can. This is usually reserved for the goliaths in personal care, but thankfully the small vegan brand Lanmeri has their own. Lanmeri Growth Hair Serum uses proprietary plant-based formula that helps hair grow just like the big dogs.

23. Act+Acre Cold Processed Apple Stem Cell Serum

Act+Acre Cold Processed Stem Cell Serum is one of the very few hair care products on the market to use groundbreaking stem cell research in its formulation. This serum contains a clinically proven method that harnesses the power of Swiss apple stem cells to protect hair follicle stem cells against premature hair loss and hair density reduction.

Act+Acre didn’t stop there. They upped the ante and infused bamboo and pea extract, both of which are clinically proven to support collagen production that naturally occurs on the scalp. Your scalp ages six times faster than the rest of your skin. It’s time to help slow down the clock on its aging with Swiss apple stem cells.

24. hers Hair Regrowth Treatment

Hers, the women centered counterpart to their sister (or would it be brother?) brand hims, has some truly unique and effective hair care products that should not be slept on. Hair loss affects everyone, and is actually quite common, so chances are that there is an equivalent product from hims for all the dudes out there. For the ladies, hers Hair Regrowth Treatment is your ticket to fuller and faster growing hair.

This minoxidil 2% topical solution penetrates deep into your scalp to activate hair follicles and extend your hair’s natural growth cycle. According to hers, this treatment was clinically proven to regrow hair that is thicker and fuller in just three to six months. Sensitive skin might take longer to reach the breakthrough period.

25. Remilia Hair The Cosmocap

Capsules are so hot right now. First popularized by RoC’s retinol capsules in the skincare space, it was only a matter of time before they made their way to haircare with Remilia Hair’s The Cosmocap daily hair capsules. We predict a confused look on your face. No, you don’t eat these like Flintstone Gummies.

These biodegradable capsules contain a plant-based vitamin serum that is formulated to reduce frizz and breakage by up to 43 percent just after one use. If split ends, tangles, and breakage are keeping your hair from growing in as it should, these cute little capsules are for you. The best part is that they’re probably the most travel friendly hair serum out there!
