Frizzy hair? Constant flyaways? You're not alone. Frizz can turn even the best hair day into a challenge, which is why Garnier's latest keratin range is generating buzz.

Promising visible results after just one use and days of sleek, glossy, flyaway-free hair, the affordable four-step routine sounds almost too good to be true. So I put the claims to the test to see if it lives up to the hype. 

Garnier Keratin Sleek Shampoo, 200ml £8

Designed to gently cleanse, this shampoo is the first of four steps in the Keratin Sleek routine. 

While cleansing, it infuses your hair scalp with the 4 per cent Keratin Smoothing Complex and ultra-nourishing argan oil. 

This helps smooth the hair, leaving it feeling soft, silky, shiny, and frizz-free.

Garnier Keratin Sleek Conditioner, 200ml  £8

Unlike many conditioners, this has managed to strike the balance between hydrating and lightweight, meaning your hair will be thoroughly conditioned and detangled, without being weighed down. 

The second step in this routine, this conditioner (with 10 per cent Keratin Smoothing Complex) was designed to soften, and majorly enhance shine.

If you've ever looked into a salon keratin treatment, you'll know the results can be impressive - but so is the price tag. So when a haircare range promises similar smoothing benefits at home for a fraction of the cost, it's hard not to be intrigued.

Garnier's four step routine cost from just £8 a bottle, and while it's not semi-permanent like salon treatments, it could be an easy, affordable way to get  hair that looks noticeably softer, shinier and more manageable from the very first wash.

Powered by an advanced Keratin Smoothing Complex and enriched with nourishing argan oil, the range is designed to tame frizz, smooth flyaways and boost shine without adding extra effort to your haircare routine. And the results speak for themselves: after using the full system, testers reported hair that looked up to 93 per cent shinier than before - the kind of transformation you'll be keen to show off. But what did I think?

What did I think of the Garnier Keratin Sleek range?

It made my hair sleek, shiny and free of flyaways

I knew that the Garnier Keratin range was supposed to make my hair sleek and shiny, but I didn't realise quite how effective it would be. 

The shampoo lathered up beautifully, and after double shampooing (a must in my opinion), my scalp felt cleansed and clean, without feeling completely stripped. 

I loved the Keratin Sleek Conditioner and how it weightless and soft it makes my hair feel even when wet. 

As someone who tends to have relatively flat and easily-greasy hair, I was a little dubious of using the hair mask as well as the conditioner (to be done twice a week). But I soon ate my words, because I don't think my hair has ever felt so good or looked so healthy after a shower. 

The mask has a really thick and creamy consistency, and unlike most other masks I've used, didn't drip everywhere - less wasted product is always a win!

The star of the show is the Diamond Sleek Smoothing Spray. I fully saturated my towel-dried hair, and blow dried in sections as instructed. The result? Glass-like hair, and my flyaways are a thing of the past! 

I've had keratin treatments on my hair in the past, and I genuinely think that this simple haircare routine gave me the same result - and for a fraction of the price. 

Anyone looking for soft, silky hair on a budget, give the Garnier Kertain Sleek range a go, I don't think you'll be remotely disappointed.  

Many things, such as sun exposure, heat styling, and colouring or bleaching can break down naturally occurring keratin, making your hair weak, brittle or dry - meaning sometimes you need a little something to add it back. 

And while you could opt for a keratin treatment at a salon, the new Keratin Sleek range from Garnier is a far more cost-effective and efficient method of revitalising your hair. 

Perfect for those with dry or dull hair, this new range from Garnier promises to transform those lacklustre locks in as little as one hair wash. 

This formula utilises the hydrating power of argan oil to deeply hydrate the hair, helping restore moisture to dry or brittle tresses. The vitamin E in the argan oil also helps strengthen the individual strands, leading to less breakage and split ends. 

This simple four step routine couldn't be easier to use. The first stop is the Keratin Sleek Shampoo, which not only leaves you with a clean scalp and hair, but is infused with 4 per cent Keratin Smoothing Complex, helping smooth the hair and reduce frizz immediately.

To follow, use the Keratin Sleek Conditioner, infused with an impressive 10 per cent Keratin Smoothing Complex, and argan oil, leaving hair soft, shiny and thoroughly nourished - and all without weighing it down. 

Then, as a once or twice weekly extra boost, apply the ultra-rich Keratin Sleek Mask enriched with 13 per cent Keratin Smoothing Complex. This works to often and de-frizz from root to tip, and even leaves hair feeling up to 10 times smoother for up to three days.

The final step? The Diamond Sleek Spray - formulated with 8 per cent Keratin Smoothing Complex, this multi-purpose spray acts as a heat protectant (against humidity and temperatures up to 230°C from blow drying, curling or straightening). 

It also coats each individual strand of hair, to enhance light reflection - with just one use, your hair will quite literally shine bright like a diamond for up 100 hours - and remains lightweight, and with non-greasy texture, completely revitalising dull and drab hair.

The third step, this mask is the real game changer when it comes to this smoothing routine. 

Formulated with a 13 per cent Keratin Smoothing Complex, this rich mask delivers smoothness, shine and frizz-control from root to tip. 

Simply apply once or twice a week, and voila! Silky, shiny hair.
