These hair serums are your new BFFs for fighting frizz and tackling humidity (1)

Turns out, the difference between a good hair day and a bad hair day is a hair serum. From encouraging growth to preventing colour fading and even helping to speed up your blow-dry (yes, that’s a thing), today’s best hair serums are here to solve your every demand, no matter what your budget may be.

But, like the rest of the beauty industry, the shelves are awash with choice, so locating the best one to suit you can be challenging. Luckily, we've spritzed many a serum so can point you in the right direction. But there are a few things we have to run through first...

What is a hair serum used for?

Once you cleanse your skin, you likely go in with some sort of face serum to boost all the benefits of said cleanser, right? Well, think of hair serums in the same way. They can be used before or after you shower to give your hair that boost of shine or hydration that your shampoo may miss.

As we inch towards the summer months (hurrah!) a hair serum may be your new BFF if yours is prone to humidity puff-ups or if you're dealing with a bit more frizz than preferred. A frizz-focused product will often contain moisture shields, such as lanolin and silicone, to create a humidity-proof barrier over the hair, thus keeping a sleek and polished look.

Better yet, many of these clever formulas also contain heat protection, so it's a good idea to slather on a serum before you switch the straighteners on. Better yet, hair serums aren't just for wet hair; use one on dry ends to keep them looking healthy and soft throughout the day.

Do hair serums work for all hair types?

The hair world has come a long way in recent years, so no longer does a one-size-fits-all policy apply. If you're looking for some deep nourishment to seal split ends, Virtue's Split End Serum is an industry fave that stylists swear by.

Looking to protect that pay-day balayage? Get your hands on Gisou's Honey Infused Hair Repair Serum: it will provide insane shine, nourish brittle strands and restore following heat damage.

For curls that need a little encouragement, Andrew Fitzsimons' Fantasy Curls Serum will lend instant definition, while Monica Geller-style locks will benefit from Ouai's Anti-Frizz Creme. And because scalp health = hair health, we all should invest in The Nue Co's Supa Thick Hair Treatment.

Now the only question is, which bottle? Scroll down to shop the stand-out serums that really stood up to the beauty team’s scrutiny and thank us later for your glossy, healthy manes.

Andrew Fitzsimons' client list may include the entire Kardashian family, but that doesn't mean he isn't as passionate about your hair as he is our favourite TV family's.

With his namesake line, Andrew wanted to ensure everyone was included, especially curls and coils. He calls his Fantasy Curls Nourishing Anti Frizz Serum his "secret weapon" for defining and moisturising individual curls.

Oh, and even better it can be used on wet and dry hair.

Moroccanoil Treatment

Perhaps the most-loved hair serum on the planet, Moroccanoil's original treatment is indeed worth the global hype.

It's suitable for most hair types (those with fine or blonde hair should opt instead for the lighter version) and works double-duty to reduce frizz, tame flyaways, stop puffiness and enhance shine.

Apply it to wet, damp or dry hair: it wont let you down.

Virtue's Damage Reverse Serum is one of the smartest formulas to hit today's shelves. Doing exactly as it sounds, the meticulously formulated cream contains ingredients that will reverse heat damage.

It contains the brand's patented Alpha Keratin 60ku – a protein that's identical to the kind already present in your hair – which works to heal the broken fibres inside the hair cortex, helping to strengthen and improve elasticity. It may be a little spenny, but if you're serious about hair repair it's going to deliver transformative results – trust.

Best hair serum for boosting shine

Gisou Honey Infused Hair Repair Serum

These hair serums are your new BFFs for fighting frizz and tackling humidity (6)

Negin Mirsalehi built Gisou with a deep-rooted passion for beekeeping, an industry that's been a part of her family for generations. Not only good for spreading on toast, but you'll find that honey is a powerful emollient and humectant which increases shine and moisture.

Gisou's Hair Repair Serum holds tiny beads containing honey and hydrating oils which burst on application. Not only does this give your hair some next-level shine, but the serum works to boost moisture and restore heat damage. And let's have a moment for the cute packaging too.

Best hair serum for split ends

Living Proof Triple Bond Complex

These hair serums are your new BFFs for fighting frizz and tackling humidity (7)

Split ends will be the least of your worries after using Living Proof's Triple Bond Complex. This clever cream heals all three bonds found in the hair – hydrogen, ionic and covalent – by feeding strands with its 3D Fortifying Technology.

Essentially, this rebuilds the hair from the inner cortex to the outer cuticle to re-fuse bonds and cure split ends. Over time you'll notice stronger, shiner and healthier strands.

Best serum for fine hair

The Ordinary Multi-Peptide Serum for Hair Density

These hair serums are your new BFFs for fighting frizz and tackling humidity (8)

This science-backed bottle is living proof that long, healthy hair isn’t always a result of triple-figure treatments.

The water-like consistency is cleverly formulated with a peptide complex – which essentially improves density by stimulating follicles – and added caffeine encourages hair growth.

Plus, it leaves no sticky residue behind, so you can apply it whenever you have time, not just when you shower.

Best hair serum for coarse hair

Living Proof No Frizz Smooth Styling Serum

These hair serums are your new BFFs for fighting frizz and tackling humidity (9)

Living Proof's No Frizz Smooth Styling Serum (try saying that drunk) was specifically formulated for coarse and thick hair. It's loaded with rich humectants and nourishing ingredients that seal in moisture, preventing brittleness and frizz in low-porosity strands.

Plus, because it's made without heavy silicones, it increases shine and makes hair much easier to slide a brush through. Tangles be gone.

Best hair serum for taming frizz

Ouai Anti Frizz Creme

These hair serums are your new BFFs for fighting frizz and tackling humidity (10)

When one of the coolest hair care brands on the planet launches an anti-frizz cream, you know it's going to be worth your £££. Ouai's new treatment is a real smooth operator. The creamy formula locks in flyways and encourages a sleek finish, but does so without weighing down strands or turning them greasy.

Just note, frizz-fighting formulas are designed to hydrate and smooth, so you'll need something a bit more heavy-duty to set a style in place or to define curls.

Best hair serum for growth

Typebea G1 Overnight Boosting Peptide Serum

These hair serums are your new BFFs for fighting frizz and tackling humidity (11)

Sorry to disappoint, but you can't apply hair serum and expect Rapunzel-like lengths in just a few weeks. It ain't gonna happen. But, to sprout new baby hairs, a growth serum is your best bet.

Typebea's Overnight Boosting Peptide Serum is a leave-in, traceless treatment, designed to prevent hair loss and promote growth. Massage a few drops into your noggin and work in with a scalp massager. In just a few weeks, you may spot some new growth thanks to the crew of stimulating peptides.

Arkive is founded by hairstylist Adam Reed, who coined the term 'headcare' as he believes we should take as much care of our noggins as we do our faces. Adam knows that healthy hair begins with a healthy scalp, which is why his Scalp Serum should be used by everybody, no matter your curl type or texture.

Think of it as skincare for your head and apply when your hair is still damp post shower. Healthy growth and shine will soon be yours.

Best hair serum for blonde hair

Kerastase Blond Absolu Cicaplasme Treatment

These hair serums are your new BFFs for fighting frizz and tackling humidity (15)

Over-processed hair can be a pain to work with: if you’ve gone heavy with the bleach, you’ll probs be familiar with the feeling of crispy strands.

Yes, maintaining a bright blonde is a priority (as it should be if you’ve dropped £££ on it), but in our opinion, if you want the blonde, you gotta control the breakage – and this is the main man for the job.

Hyaluronic acid and edelweiss flower work away to smooth unruly lengths and seal split ends, while the opalescent lavender tint neutralises yellow tones. Plus, it’s got some major heat protective action going on (which is a must for colour-treated waves).

It doesn't leave a greasy residue, so you can add it to your routine without having to schedule it around wash day. Easy.
