The Best Hair Growth Shampoos For Lengthy Locks

We often get told not to wish our lives away, but when you’re growing out a bad haircut or willing your hair to grow longer, you’d be forgiven for impatiently ticking the days off.

Tipping your head back and staring into the mirror; pulling your GHDs through each and every lock until they’re poker-straight; applying and styling and all-round willing your hair to grow longer — sometimes it doesn’t matter what you do: your hair stubbornly refuses to grow.

But that just means it’s better to bring things back to the basics: with the addition of a hair growth shampoo that can renew your long, luscious locks and hair regeneration like you’ve never seen before.

Hair thinning? A thing of the past. It’s time for hair growth, and by that we mean incorporating a shampoo for hair growth and thickness so impressive you find yourself airly flicking your lengths around like something out of a shampoo advert.

If you’re looking to stimulate hair growth, regrow hair, or just add a hair thickening shampoo into your routine, you’re in the right place.

Kerastase: Best overall hair growth shampoo

It doesn’t matter whether your hair goals are smooth and silky Rapunzel-esque lengths, growing out a haircut that didn’t go according to plan or dealing with thinning hair: Kerastase’s Bain Extentioniste Shampoo will calmly take matters into its own hands with a nourishing, dense formula that waves goodbye to all of your hair woes once and for all. Making slow growth a thing of the past, you’ll start to appreciate the strength and health of your hair when you’ve successfully transitioned to using this shampoo. 

Its list of winning ingredients is suitably long and features some hair-boosting favourites like taurine, castor oil, creatine R and ceramides to bring your hair back to its optimum health. The addition of taurine also works to nourish your scalp, which means that not only will your current lengths see big improvements, but your new hair will be healthier, too.

Best for: Levelling up your hair into the crown you’ll never take off.

Oribe: Best premium shampoo for hair growth

The simple act of standing in the shower is elevated once you’ve swapped your everyday bottle of shampoo for a bottle of Oribe’s Gold Lust Repair & Restore Shampoo. There’s a chance you’ll even subconsciously mistake this bottle for being “gold dust” rather than “gold lust” — partially because it’ll feel just as luxurious when lathered into your hair but also because you’ll look after this bottle as carefully as if it were made of real gold.

The repair and restore shampoo has two main areas of expertise. Combining cypress, argan and maracuja extracts, it rejuvenates and strengthens your existing hair while paving the way for your new hair to grow back in its healthiest state. Vegan, cruelty-free and gluten-free, it’s the ultimate answer to restoring sleek, smooth hair without adding any unwanted chemicals or ingredients to your hair care routine. 

Best for: Making every hair wash feel like a spa day.

Pura d’Or: Best value hair growth shampoo

Pura d’Or is one of the OGs in the world of hair growth shampoos and it gently but firmly leads the way when it comes to encouraging consistent growth. A selection of potent ingredients combine to create a formula that wastes no time adding a burst of energy to your hair. The key ingredients in the Original Gold Label Anti-Thinning shampoo include biotin and a proprietary herbal DHT blend, which work together to discourage shrinking hair follicles and keep the existing hair in top quality condition. 

Biotin also adds an extra dose of nutrients by allowing new hair to grow through with an extra layer of armour. Nettle extract, pumpkin seed and black cumin seed oil are some of the other crucial ingredients in this vegan-friendly and cruelty free shampoo, making it a brilliant allrounder that doesn’t cost a fortune. 

Best for: Enjoying those newly necessary trips to the hairdresser’s.

Aesop: Best natural hair growth women’s shampoo

Aeosop’s winning combination of all natural ingredients might seem too good to be true but it just goes to show that sometimes you don’t need a long ingredients list for success. And, in true Aesop form, this is a shampoo with a smell as pleasing as its results. The Volumising Shampoo uses one important ingredient for success: Polyquaternium 67. Best suited to those with limp, fine or thin hair, this miracle shampoo offers the same effect as vigorously shaking your head upside down – but with style. 

Adding lift and bounce where previously there was none, you’ll start to notice your hair quickly growing longer as well as thicker. After a few washes, you’ll start to notice your hair feels bouncier and lighter; almost as if it’s starting each day with the announcement of some good news and a strong coffee.  

Best for: Letting your newly thickened hair air dry and loving the results.

Pure Biology: Best stimulating hair growth shampoo

Pure Biology is the shampoo equivalent of the friend who always comes with everything to hand: a pen, notebook, tissues and even a change of clothes. But in this case, each of those necessities is replaced with a hair care necessity: biotin, keratin, castor oil, coconut oil, vitamin B, vitamin E, saw palmetto, green tea extracts and more. Think of a beneficial ingredient to throw into a hair growth shampoo and you’ll almost definitely find it in this bottle. 

As a result, the Pure Biology Revivahair Shampoo is one of the best hair growth shampoos you can buy, with ingredients designed to thicken, stimulate and all round nourish your hair without any damaging factors at all. A brilliant everyday shampoo, it manages to do all of the above without weighing hair down or adding any oils, making it ideal for those with dry hair right through to those who have oily roots.

Best for: Making your scalp stand to attention, Sergeant Major style.

Philip Kingsley: Best volumising shampoo for hair growth

You’ll feel a little like you’re walking out the hair salon everyday once you’ve incorporated Philip Kingsley’s Body Building Shampoo into your daily routine. Undoubtedly the best hair growth shampoo for volumised hair, a quick lather with this bottle and you’ll feel like you’ve experienced a blow dry on the daily. Body building by name and body building by nature, this shampoo somehow manages to do the impossible and combines a weightless formula with a shampoo that adds just enough weight for great effects. 

Calming flyaways while giving your overall hair an impressive boost, it utilises ingredients like strengthening keratin proteins and natural cellulose to thicken each individual strand. Say goodbye to frantic morning routines involving a barrel brush, head upside down and hairdryer manipulated for hours on end: this shampoo will give you the same overall effect but just as a result of its magic, rather than your own hard work. 

Best for: Making lifting part of your daily routine in the gym and the shower.

Klorane: Best strengthening shampoo for women

Gone are the days of wincing when you accidentally catch your hair in your necklace, or having to ever so gently remove a hair tie without breakage. It’s time to add a strengthening shampoo to your hair care routine. Klorane’s Shampoo with Quinine and B Vitamins should almost be advertised as one of your five a day, thanks to the impressive and almost unbeatable effect it can have on your scalp. 

This is a shampoo that’s confident in its ability to make a difference – and rightly so. As one of the first hair growth brands to take to the stage, Klorane knows what it’s talking about when it comes to finding desired results. Fortifying, stimulating, strengthening and revitalising: this shampoo is the closest thing you’ll find to a spa day designed just for your head. 

Best for: Ruthlessly tying your hair back with reckless abandon once again.

Olaplex: Best clarifying hair growth shampoo

If the devil on your shoulder is frizz, dry hair or ends that keep snapping off, then Olaplex is the angel on the other shoulder. One of the biggest household brands in the world of hair care, Olaplex can’t really be faulted and is more than worthy of its superstar status. One of those brands that’s eventually on everyone’s lips, you may be hesitant at first of believing such lauded claims, before trying the shampoo yourself and being converted forevermore. 

Olaplex’s No.4 Bond Maintenance Shampoo will quickly become your new haircare staple, thanks to its pure variety of ingredients and immediate results. You could get away with just using this clarifying shampoo once and admiring its results, or you could treat yourself to regular usage and get used to smooth, soft hair that refuses to stop growing while shining with a healthy glow.

Best for: Finally getting on that Olaplex hype train and enjoying every minute.

Sachajuan: Best hair thickening shampoo for women

It’s all well and good encouraging your hair to grow longer, but it’s not quite as enjoyable if your hair is longer but thin, snapping and generally not in healthy shape. So, while you’re working on getting your hair to grow down, it’s also invaluable investing in products to help each individual hair follicle grow an extra layer of protection. Sachajuan’s Thickening Shampoo will almost have you second guessing the limits of science with its quick results. 

This understated bottle comes with results that can’t be overstated enough, and that’s all thanks to its Ocean Silk Technology. Just as smooth and luscious as its name suggests, this shampoo will transport you and your hair into movie set levels of enviable hair. Repairing your existing hair while ensuring all new hair comes through with a gorgeous shine, you’ll treasure this bottle as soon as you’ve witnessed its results. 

Best for: Causing your family and friends to run their fingers through your hair.

Viviscal: Best densifying women’s shampoo

A premium quality densifying shampoo will take one look at thinning hair and shake it up with impressive results. Sure, they might not be visible after a single shampoo but good things come to those who wait and your patience levels will more than pay off with your thicker, softer and all round better conditioned hair. Viviscal’s Gorgeous Growth Densifying Shampoo promises just that: impressive hair growth that’s witnessed high levels of TLC and is in a position to thrive. Famed for its long term results on all and any kind of hair, Gorgeous Growth is accompanied by Delightful Depth, Serious Smoothness and Terrific Texture. 

If you have shorter hair, use this product like a hair mousse for best results. Doing this also comes with the added benefit of experiencing the delicious scent for longer, rather than just standing around in the shower trying to breathe in every last bit of it. 

Best for: Making ‘dense’ sound like an aspirational thing for the first time ever.

Davines: Best shampoo for fragile hair

Not only is Davines’ Energizing Shampoo a great choice for anyone who wants their bathroom cabinet to be just as stylish as the rest of their life, but it’s also a brilliant option for those who have fragile hair that refuses to withstand heavy products. It can be tricky trying to find a hair growth shampoo that’s targeted towards fragile hair without overpowering it, but this shampoo promises just that. 

Its careful combination of ingredients is specifically formulated for thinner hair, promising to whisper nurturing words to encourage growth. The main ingredients of success in this shampoo are caffeine phytoceuticals, which stimulate circulation and improve hair elasticity, preventing loss and keeping new hairs healthy, too. Refreshing and revitalising, this Italian-made brand is sure to become a repeat purchase for its all-encompassing effect on your scalp and hair follicles.

Best for: Bringing your timid lengths out of their shell with a huge confidence boost.

Virtue: Best full shampoo for hair growth

Much like eating a huge meal or quickly drinking an entire bottle of water, Virtue’s Full Shampoo will keep you stuffed for hours on end in the best way possible. It’s hard to sum up exactly where this shampoo especially thrives, because its list of benefits and skills never seems to end. As well as cleaning your hair like any good shampoo will do, the Full Shampoo also thickens, volumises, lifts and plumps your hair from the roots upwards. 

It’s full in every sense of the word; from its thick, dense formula to the way your hair feels after a quick lather. The box ticking continues with the suitability of this shampoo: it doesn’t matter whether you’ve got thin hair, colour treated hair or hair that’s flat – this shampoo will work its magic with hydrolyzed quinoa and biotin in a way that eating your superfoods could never achieve. 

Best for: Effortlessly ticking every box in the hair growth world.

Redken: Best anti-breakage shampoo

There’s no need to mourn the loss of your GHDs or curling wand any longer for fear of causing extra breakage: the best anti-breakage shampoos will laugh in the face of anything resembling weak hair strands, with a powerful formula that seems to almost magically coat every single hair strand. 

Sitting high up on its metaphorical throne, Redken’s Extreme Length Shampoo is the winning solution for anyone whose hair grows to a certain length before seemingly accepting defeat and snapping. If you’re sick of your hair reaching shoulder length and refusing to grow any longer, this is the shampoo to use to see long-lasting results. The anti-break shampoo works thanks to its infusion of biotin, which strengthens existing lengths and promotes healthy new hair at the same time.

Best for: Rightfully deserving its seemingly endless 15 minutes of fame.

Rene Furterer: Best hair growth shampoo for frequent use

Gym bunnies, hat wearers and anyone who washes their hair everyday: it’s time to sit up and pay attention. You’re probably already familiar with the notion that washing your hair less can encourage hair growth but, sometimes, that’s just not an option. Especially if you’re someone who likes to spend a morning at the gym before work but flat out refuses to turn up with anything less than sleek, stylish and most importantly clean locks. 

Rene Furterer’s TRIPHASIC Strengthening Shampoo is designed with you in mind: pulling together an impressive shampoo that withstands daily usage while keeping your hair in tip top condition. It combines ATP, pfaffia extract and encapsulated essential oils to energise the scalp in a way that your standard daily shampoo could never. Make the transition from your go-to shampoo to a bottle of Rene Furterer and you’ll quickly reap the benefits of clean, healthy and crucially strong hair. 

Best for: Squeezing in an extra shower just to use it again.

Briogeo: Best dry shampoo for hair growth

Slept through your alarm? Dry shampoo. Hot water seemingly refusing to turn on? Dry shampoo. Freezing cold morning where the thought of stepping out of the shower fills you with dread? Dry shampoo. A good dry shampoo will convert flat, lifeless hair into something that resembles a put together look. But a great shampoo will take it one step further, with a formula that acts almost as impressively as normal shampoo does, without forcing you to stick your head under the shower. 

Briogeo’s Scalp Revival Charcoal + Biotin Dry Shampoo will save you time and styling energy, with a dry shampoo that storms ahead from the years when you accepted defeat with dusty hands and a faint grey shadow over your roots. But not only does this dry shampoo do its job of uplifting your hair, it also works to keep it strong and nourished, with a combination of charcoal, clay, tapioca and rice starches.

Best for: Replacing a cup of coffee as your ‘running late’ morning necessity.

Kerastase: Best hair growth shampoo for oily hair

Apply to wet hair. Lather, rinse, repeat… and declare with delight to your friends that you’ve discovered your new haircare saviour. There aren’t many shampoos out there that manage to keep hair thick and healthy without causing a build up of oil. And that’s a problem you likely want to avoid, if you’re someone who has oily hair in the first place. But Genesis’ Bain Hydra-Fortifiant Shampoo acts as the perfect midpoint: stripping away grease and removing sebum and other pollutant particles from your scalp before injecting a huge dose of moisture straight back in. 

The moisture in question is formulated with Edelweiss native cells and ginger root, which you might not see that frequently on shampoo bottles but fully deserve their gold medals for impressive results. Together, these ingredients provide oil control, slow down hair breakage that comes from brushing your hair, and fortify from the roots upwards, all at the same time. 

Best for: Turning oily roots into dazzling shine with growth along the way.

Ultrax Labs: Best women’s shampoo for regrowth

Ultrax Labs’ Hair Surge is basically a stylish science project revealed after years of hard work, determination and endless studies in the hair industry. This is a brand that’s perpetually top of the class, with a range of hair growth products designed with only the best ingredients that are proven to be highly effective. If the Hair Surge shampoo was a science project, it would be the obvious overall winner, putting every other product to shame and taking the gold medal without even waiting for applause. 

Because this shampoo really does have it all: from the key ingredients like caffeine, ketoconazole and saw palmetto to the integrated essential oils and other active ingredients that combine in a real definition for success. Use this shampoo in place of regular shampoo and say hello to regrowth, and goodbye to shedding hairs without even touching your head.

Best for: Calming you down after a hair disaster.

Ouai: Best hair growth shampoo for fine hair

Fine hair grows a life of its own with the addition of Ouai’s Fine Hair Shampoo. As the name would suggest, this shampoo is specifically formulated to thicken, nourish and add depth and character to even the very thinnest hair. 

A game changer for anyone looking to naturally thicken up their hair, Ouai’s Fine Hair Shampoo combines biotin, chia seed oil and hydrolyzed keratin to create a sort of superfood smoothie that you’ll luxuriate in every time you step in the shower. As well as being an absolute joy both while lathering up and then styling your hair, this is a shampoo with a beautiful fragrance to match. Orange, peony, magnolia, jasmine, musk and orris all work together for an incredibly floral fragrance that’ll follow you about your day. 

Best for: Adding incredible depth without weighing you down.

Évolis: Best growth shampoo for colour-treated hair

You might get told to pick your poison, to focus on one problem at once or to simply accept that your beautiful new dye job isn’t going to last very long if you’re also looking to strengthen and grow your hair. Most of the time, colour-friendly shampoos aren’t designed with growth in mind and growth shampoos don’t even consider their effects on colour treated hair. But, that seemingly huge gap in the market was promptly filled by Evolis and its Promote Shampoo. 

Almost seemingly too good to be true, the Promote Shampoo transforms hair from thin, lank or overworked with a nourishing formula that promises a whole 180. Some of its core ingredients include antioxidants like baobab and keratin that promise smooth, straight locks that are just as vibrant as when you left the salon. 

Best for: Keeping close to you after a dye job like a childhood teddy.

Grow Gorgeous: Best women’s shampoo for damaged hair

If Grow Gorgeous was a juice, it would be one made entirely from superfoods. If Grow Gorgeous was an alcohol, it would be a spirit so strong that you’d sip a single shot’s worth and that would be enough. Grow Gorgeous as a shampoo is one of the most concentrated formulas available: a deep, dense and thoroughly nourishing shampoo that’s perfect for anyone with damaged hair. 

Even if you’ve been bleaching your hair a few times a year for the last decade, this is the shampoo that’ll restore it to its natural glow after a few washes, while encouraging new hair to grow back faster and even stronger. It uses amino-acids, caffeine, proteins, biotin and b-vitamins to do all of the above so successfully, and works on all kinds of hair from colour treated to sun damaged, thin or thick hair or anything in between. 

Best for: No longer regretting those endless days relaxing in the sunshine.

Nioxin: Best shampoo for thinning hair

The same way you associate tonic with gin, butter with bread or oil with vinegar, you’ll immediately put thinning hair and Nioxin together. One of the most recognised brands in the world of hair care, Nioxin’s System 2 Cleanser Shampoo is the shampoo equivalent of the comfort blanket and hot cocoa you run to when bad things happen. This purifying shampoo gently but firmly brings your hair back to its prime condition to encourage healthy hair growth. The first step? Removing sebum, fatty acids and other environmental residue from the scalp and hair. 

The second step is where the magic happens: the potent formula strengthens and amplifies your hair’s structure, creating a stable base for your new hair to thrive. Nioxin is one of those brands that salons rave about, dermatologists talk about as if it was their first born and friends who’ve tried the brand swear by using nothing else. It might seem slightly cult like, but it’s well-deserved.

Best for: Stopping thinning hair in its tracks almost instantly.

Laritelle: Best organic hair growth shampoo

You might typically avoid hair growth shampoos for their insistence at using chemical ingredients or strong formulas made up of words that you wouldn’t even attempt to pronounce. And, until recent times, choosing a hair growth shampoo meant accepting all of the above and picking your battles: organic shampoo or growth-spurting shampoo? Luckily, the perfect midpoint now exists in the form of Laritelle’s Organic Shampoo. 

Flat out refusing to use any ingredients that aren’t organic, it instead favours things like argan oil, rosemary and palmarosa to encourage hair growth and a healthy environment to let your scalp flourish. One of the best things about this shampoo is how ridiculously soft and smooth it makes your hair feel. By starting right at the hair follicles, it means that every inch of your crown receives the special treatment and can grow accordingly. Earth friendly and non-toxic, you’ll feel a burst of positivity each time you use it. 

Best for: Being far mightier than its ingredients list may suggest.

ArtNaturals: Best hair growth shampoo with argan oil

Along with smelling beautiful and feeling extra luxurious, argan oil is a brilliant addition to any shampoo if you’re looking for silky smooth hair that refuses to stop growing. The vitamins in argan oil promote hair growth with no limits, and ArtNaturals’ Argan Hair Growth Shampoo is a perfect example of doing just that. The list of benefits from this shampoo is almost never ending, starting with boosting and rejuvenating hair and ending with gloriously thick, healthy lengths. 

A sort of armour if you’re heading out into the sunshine or favour dyeing your hair frequently, the addition of argan oil in this shampoo means you can tan as much as you like or dye your hair a whole rainbow of colours without seeing negative effects. And, if you weren’t convinced, keep in mind that argan isn’t the only shining star in this formula: biotin, keratin and caffeine are the backing dancers also keeping your hair looking incredible. 

Best for: Not being sure whether to smell or touch your hair first.

Philip B: Best women’s shampoo with peppermint

That fresh, clean and overall enjoyable feeling you get straight after you’ve brushed your teeth? Imagine the same effect on your hair and you’ll start to understand just how good it feels to incorporate peppermint into your hair care routine. And as well as being almost unbeatably refreshing, peppermint helps to stimulate the scalp and encourage hair growth from the inside out. 

Philip B’s Peppermint Avocado Shampoo is a famous product and one of the brand’s best-selling, thanks to its ability to transform hair into something bouncy, soft and ready for action no matter what it looked like before you stepped into the shower. Along with peppermint, this shampoo features 16 plant-based extracts, all of which come together to form a nourishing bond on your lengths with a tingly, cooling burst that’ll keep you energised all day long. 

Best for: Ending each hair wash with a spring in your step.

Briogeo: Best hair growth shampoo with biotin

Briogeo’s Blossom & Bloom Ginseng and Biotin Volumizing Shampoo brings on the same kind of mood booster as opening the curtains to a morning of glorious sunshine. Beautifully smelling and incredibly effective, this hair growth shampoo is uplifting and invigorating, encouraging hair to grow thick and long with a renewed vigour that you might have accepted was never going to appear. 

It does this with a unique combination of ingredients that work together to improve the overall health of your hair while ensuring new hair grows in the perfect conditions. Especially suitable for those with thin or fine hair, this shampoo uses ginseng and vitamin B5 alongside its superstar addition of biotin to moisturise hair while making it appear thicker. The biotin in the Blossom & Bloom shampoo works its magic by stimulating keratin production in the hair and can also increase the rate of follicle growth, making new hair grow faster. 

Best for: Hair that acts like a people-pleaser and refuses to stop thriving.  

Dr Hempster: Best shampoo with hemp oil for women

Hemp oil is one of the newly popular kids on the block when it comes to hair stimulating ingredients and it’s something you’ll want to get fully onboard with. Hemp encourages hair growth thanks to its high percentages of protein, vitamins and minerals. It also contains a lot of fatty acids, which promote blood circulation to the scalp and may encourage even faster hair growth. Dr Hempster’s Hair Loss and Biotin Shampoo is a natural and organic shampoo that’s perfect for anyone growing a little tired of waiting for hair loss. 

Its natural makeup also means it’s suitable for those with sensitive skin. Along with hemp oil, it uses biotin to cleanse and thicken, saw palmetto to fight DHT stimulating enzymes, wheat protein for extra elasticity in your lengths and argan oil rich in antioxidants to stimulate hair growth. It’s basically a whole collection of impressive shampoos rolled into one unique bottle. 

Best for: Buying the rest of the range and declaring hemp the buzzword of 2021.

OGX: Best budget hair growth shampoo

Not only is OGX Thick & Full shampoo an excellent budget friendly shampoo for hair growth but it also comes with a bergamot, jasmine and vanilla scent that you’ll rave about long after you’ve stopped gazing at your newly long hair in wonder. OGX takes things back to basics in the best way possible with this shampoo, thanks to its nature-first approach and addition of biotin and collagen. 

Hair gets the full treatment with results that suggest a far more expensive shampoo, with renewed bounce and energy. Nutrient rich and smelling irresistibly good, this paraben-free is gentle on your tresses while promising powerful results. Suitable for all hair types, you can expect to see abundant hair growth that’s in healthy condition no matter whether you have straight or curly, thick or fine or even colour treated hair. 

Best for: Pleasing your hair and your wallet equal amounts.

Guide to the best hair growth shampoos for women

While supplements and serums might be beneficial for hair growth, you’re missing an easy win if you’re skipping out on a hair growth shampoo. 

When choosing a hair growth shampoo, choose a bottle that includes important ingredients that stimulate hair growth and prevent hair thinning. Some of the best include:

Stimulating ingredients

Caffeine, taurine and essential oils like peppermint all stimulate the scalp, encouraging renewed, fresh hair growth with an improved blood flow to your head.

DHT-blocking ingredients

Dihydrotestosterone (DHT) is an androgen that’s thought to encourage hair thinning by shrinking your hair follicles. Ingredients that block hair-suffocating DHT like saw palmetto, pumpkin seed oil, lavender oil and biotin all work to counteract these effects and encourage fresh hair growth.

Hair nourishing ingredients

Shampoos featuring oils (castor oil especially) and serums work on your existing hair, providing a sort of shield from environmental factors and heat damage. While these won’t encourage hair growth straight from the scalp, they work to keep your lengths healthy and prevent damage. 

Of course, you can also stimulate hair growth and keep existing hair healthy by sleeping on a silk pillowcase, avoiding direct sunlight on your hair, or using a scalp revival device like Briogeo’s famed massager.
