Top 14 Best Heat protection of 2021

How we did the test

We carry out our tests ourselves and test all products as they are intended to be used in reality. In our test of heat protection, the products were used on several occasions and under different circumstances. Each product was tested with both a hair dryer and straightener and in wet and dry hair. This allowed us to assess the product’s different properties. We also looked at how the product affected the hair the day after washing. The parameters below formed the basis for our assessment.

  • Application: Is the product easy to apply? Is it economical or do you need a lot? Can you use it on both wet and dry hair?

  • Softening: How good is the product at making the hair soft and smooth? Does it keep the hair strands separate during blow drying? Is the result undamaged, healthy hair or frizziness?

  • Shine and properties: Does the product provide shine and lustre? Does the heat protection product have other properties, and is it easy to combine with other products? What does the product smell like and how long does the scent last?

Our assessment is based on an overall experience of the product. We then look at the product price to see whether it’s good value for money and to allocate a score.

1. Label.m Heat Protection Mist – BEST CHOICE HEAT PROTECTION

A heat protection spray for hair that’s styled frequently

Type: Spray bottle

Label.m Heat Protection Mist 150ml

Label.m heat Protection Mist is a heat protection spray with a fragrance that many people appreciate. However, according to our test panel, it’s not the smell of this spray that wins hearts, but something else.

It’s not unusual for spray heat protection products to have nozzles that are anything but good. But when it comes to Label.m heat Protection Mist, our testers only had praise to give about how well the spray is distributed in the hair. The product comes out as a really fine mist, which makes it easy to apply.

This spray doesn’t just protect effectively against heat (up to 240 degrees), but also against UV radiation. This means that it’s a good idea to even use it during the sunny months as extra protection. Label.m heat Protection Mist also adds a touch of consistency to the hair, making it easier to style.

This heat protection from Label.m dries quickly, which is a big advantage when working with heated tools. Waiting for a product to dry isn’t a good use of your time. But you don’t have to do that with this heat protection.

In fact, it was the otherwise much-praised smell that made our testers wrinkle their noses a little. It does smell of hair salon, but it’s a rather sharp, strong scent, which makes it a little overpowering. On the other hand, if your hair isn’t freshly washed, it may be nice to have a boost of fragrance. It just depends what you prefer.

But the smell isn’t the important thing! This is a really good heat protection spray that quickly becomes a favourite. The fine distribution of the product in combination with quick drying and a touch of texture, means you’ll use it right down to the last drop.

2. Revlon Uniq One All in One Hair Treatment – BEST CHEAP HEAT PROTECTION

Economical and very effective heat protection spray that smells good and gives smooth, shiny hair

Formula: Liquid Format: Plastic spray bottle Price class: Budget

Revlon Uniq One Hair Treatment 150ml

This easy to use heat protection comes in a practical spray bottle and smells of hairdresser visits and newly washed hair. As the name implies, Revlon Uniq One All in One Hair Treatment is actually much more than just a heat protection spray, which also makes it a very usable product that will never collect dust on your bathroom shelf. For example, it works really well as a conditioner spray, which made it very popular with our test families with children who hate having their hair brushed. The hair is easy to brush, shiny and smooth. At the same time the spray protects your hair from the heat produced by hair dryers, straighteners and curling tongs, it also gives the hair more body and consistency.

The bottle sprays a good amount of the product evenly over the hair. It works just as well in dry as wet hair. The heat protection spray never feels sticky or greasy, but leaves a shiny result with minimum frizz. The product turned out to be a real star on damaged, coloured hair that most resembles a spiky bush in its natural condition. It smells good but not overpowering, and you can also choose between several different scents.

Revlon Uniq One All in One Hair Treatment is easy to use, good value and multifunctional – a real winner for anyone with tangled hair or brush-phobic kids.

3. Kérastase Ciment Thermique

Fantastically smooth and healthy result with lots of lustre

Formula: Cream Maximum temperature: 180 degrees Format: Tube, screw top Price class: Premium

Kérastase Résistance Ciment Thermique 150ml

A nice scent that’s reminiscent of a hairdresser’s salon spreads out when you squirt a little Ciment Thermique into your palm. The consistency is light which makes it easy to distribute it evenly throughout your hair. If you apply the cream before brushing your hair, it doesn’t help detangle the hair much, as it only has a softening effect once you use the hair dryer. But it does get fantastically soft. During blow drying, the hair strands are kept separate and don’t get tangled or frizzy, and the product works even if you’re using a simpler hair dryer. The results after use are amazingly smooth without feeling greasy. The hair simply looks really healthy.

Kérastase Ciment Thermique gives the hair a lot of shine and lustre. However, it doesn’t provide any consistency, so for styling you’ll need to supplement it with another product. Instead, this is a base product that provides the foundations for healthy, strong looking hair. This heat protection cream has been praised to the skies and although it’s expensive, given that you really need very little each time and that the results are fantastic, Kérastase Ciment Thermique is well worth the price.

4. REF Leave in Treatment

A multifunctional cream with both heat protection and moisture boosting properties

Formula: Cream Format: Plastic spray bottle Price class: Medium

REF Leave In Treatment 125ml

Do you have dry hair that thirsts for moisture? If so, REF Leave in Treatment is a really good option when you’re looking for a new heat protection product for your hair.

REF Leave in Treatment provides both moisture and heat protection in a single product. This means it doesn’t only protect your hair from high temperatures during styling, it also gives it moisture. The combination results in soft hair without frizz.

This is a cream that comes in a practical pump bottle. Depending on how long and thick your hair is, the amount you need will vary. But for shoulder length hair, our testers found that two or three pumps are plenty. You apply the cream evenly to the hair before using heated tools, while it’s still damp. This also detangles the hair, making it easier to comb out any knots.

The formula is light and your hair doesn’t feel weighed down at all. After use, the hair is smooth and looks shinier than if you don’t use the cream. The fact is that this is such a nice product you tend to apply it even if you aren’t going to use any heated styling tools.

It’s a multifunctional product that smells fresh and feels caring, which means you often reach for it when your hair needs a little boost. And even when it doesn’t. Quite simply a really nice complement to your haircare routine.

5. Björn Axén Heat Styling Protection

Pleasantly scented heat protection spray that’s distributed nicely in the hair

Formula: Liquid Format: Plastic spray bottle Price class: Medium

Björn Axén Heat Styling Protection 150ml

This heat protection spray from Björn Axén comes in a narrow plastic bottle with a pump. The bottle may not look like much, but it lasts well and the pump gives us no problems despite not using any propellant.

The spray is nicely distributed in the hair and doesn’t weigh it down. Of course this is largely a result of the formula, but also because it’s spread out so well in the hair – something you can’t take for granted with this type of spray bottle. Björn Axén Heat Styling Protection smells good and fresh – a bit like a hairdresser’s salon. The scent does disappear quite quickly, but this can be an advantage as it doesn’t overwhelm other scents you’re using.

This heat protection spray didn’t seem to have any detangling effect on the hair, but the result after using heated tools is nice and smooth. The product protects the hair from heat up to 220 degrees.

And it gets a big bonus for not only protecting when you're styling your hair. It also contains UV protection, extracted from sunflower oil, which means that your hair also has a bit more protection from the sun.

6. Redken Frizz Dismiss Smooth Force FPF 20

Easy to apply and effectively counteracts frizziness

Formula: Spray Format: Spray bottle

Redken Frizz Dismiss Smooth Force Smooting Lotion Spray 150ml

Redken’s Frizz Dismiss is a softening heat protection spray that adds lustre to your hair. The consistency is relatively thin, between a liquid and cream, and you spray it into your hair. Despite its light formula, it has a smoothing, caring result. It doesn’t have any detangling effect to speak of. So it’s best to brush your hair first and then spray the product on so you can get it where you want.

The product is intended to counteract frizzy hair, and it does this very well. Because it’s thin and you spray it on, you can also get a thin layer closer to the roots without the hair becoming greasy. This can be difficult with similar products in cream format. Frizziness stays away even during the blow drying process. You will need to brush your hair afterwards, but it doesn’t get tangled. It’s possible to overdo applying the product, which makes the hair feel heavy. You only need a very thin layer. The scent of the spray is good but mild, which means you can use it with other products. And you’ll need other products, as this doesn’t give any structure to the hair. Redken Frizz Dismiss Smooth Force FPF 20 is a good base that provides protection against heat but also adds extra shine and lustre.

7. Davines Liquid Spell

Heat protector that gives magically good results and makes the hair fresh and shiny

Formula: Liquid to foam Format: Pump bottle without propellant Price class: Medium

Davines Liquid Spell 125ml

Davines Liquid Spell is a product for thin or already damaged hair. Unlike the majority of other products that provide heat protection, Liquid Spell doesn’t promise smooth hair. Instead, it claims to provide a fuller effect while protecting the hair against heat.

And you can almost believe the liquid, which transforms into a foam when you pump it out of the bottle, really does contain a small touch of magic just like the name indicates. You see a clear difference after applying the product and starting to blow dry your hair. Thin hair immediately appears fuller and with greater volume. And if you’re used to lacklustre, damaged hair, you’ll be happy with the way it suddenly looks significantly more healthy and stronger.

Liquid Spell contains a heat activated molecule that compacts the cuticle of the hair strand, protecting it against heat. It doesn’t merely look fuller either – the results after you style it last better too, even if you don’t use other hair products. Of course it isn’t really sorcery, but your hair still looks magically great using Davines Liquid Spell.

8. hh simonsen Heatspray Protection

Nicely scented heat protector that effectively eliminates frizz and makes your hair smooth

Formula: Liquid Format: Pump bottle without propellant Price class: Medium

HH Simonsen Heat Protection Spray 145ml

Heatspray Protection from hh simonsen is shiny hair in a bottle, largely because this is heat protector combined with hair oil. The spray can be used in damp hair before you blow dry it, or directly on dry hair to prepare and protect your hair against the heat from styling tools. It protects the hair up to 230 °C, which is about the temperature of the most damaging heated tools.

The argan oil in the product makes the hair shiny and soft, and even if this isn’t a detangling spray you still feel like your hair’s a bit easier to comb out. If you smell the bottle, the scent is almost overwhelming, but once it’s in the hair the intensity reduces and there’s absolutely no problem if you aren’t sensitive to smells. Instead, your hair smells good all day long and it’s difficult not to keep sniffing strands of your hair.

The bottle is a bit dull and probably won’t be the crowning glory of your bathroom shelf, but once you've applied hh simonsen Heatspray Protection the scent is reminiscent of high-end hair salons and the contents definitely deliver what they promise.

9. Lóreal Professionnel Absolut Repair Lipidium Thermo Repair

Very nourishing and gives soft results

Formula: Cream Format: Tube

Lipidium Thermo Repair is a product in L’Oréal’s Absolut Repair series that’s intended to nourish and rebuild damaged hair. And the ends of your hair definitely feel less split after you've applied this mildly scented cream. Once you’ve blow-dried your hair, it becomes soft and shiny. But the consistency of the cream is very greasy, which makes it rather difficult to apply. Partly because the product isn’t absorbed easily by the hair and partly because it requires a certain amount of effort to apply it evenly. It’s even more difficult if you haven’t brushed your hair first. So we recommend you brush your hair first and then apply the cream. This means you can’t use this heat protector as a softener to help you detangle your hair.

After blow-drying, which doesn’t take long and doesn’t result in frizzy hair, the greasy feeling disappears. In other words, the character of the cream changes completely when it’s heated, and your hair doesn’t feel heavy or look greasy when it’s dry. The scent is nice but mild, which is good for sensitive users. As with the majority of heat protectors, the product doesn’t give any structure to the hair, so you’ll need to combine it with other styling products. L’Oréal Professionnel Absolut Repair Lipidium Thermo Repair cares for your hair beautifully and is well worth the price.

10. Joico Ironclad Thermal

Good value heat protector that gives a natural result and smells good

Formula: Liquid Format: Pump bottle with propellant Price class: Budget

Joico Ironclad Thermal Protectant Spray 233ml

Joico is a brand that often slips under the radar, which is a shame because they have a lot of good products. And Ironclad is one of them. This heat protector, which is intended for use in dry hair during styling, comes in a largeish spray bottle. The product smells incredibly good and it’s tempting to use it not only in your hair but also as a room perfume.

It’s easy to think Ironclad is a styling product, because the bottle is similar to many hairspray bottles. But this is a product that protects your hair but only provides the lowest level of consistency. The major advantage is that you don’t get the crispy surface that sprays with more styling consistency tend to give your hair. Ironclad produces a soft and flexible result, with a good helping of shine. The lovely smell fades during the day, but your hair stays soft.

If you're looking after a heat protector that doesn’t offer any other functions, Joico Ironclad is a good option, particularly if you're looking for a soft and natural result.

11. Maria Nila Cream Heat Spray

Counteracts frizz and produces a soft result

Formula: Cream Format: Spray bottle Price class: Premium

Maria Nila Cream Heat Spray 150ml

Maria Nila market their heat protector as 100% vegan, which is bang on trend. The cream is soft and quite greasy. If you spray it on unbrushed hair, it will help you comb out the tangles. This product promises heat protection and frizz control – and it really works. As you blow dry your hair, it stays smooth, and you can get really good results with a brush. Your hair becomes soft and lustrous, but the product doesn’t give any shine.

The instructions say you should only spray a thin layer onto your hair, which is worth remembering as it’s easy to apply to much. The cream is economical and if you use too much your hair will be heavy and feel greasy. One tip to get the right amount just on the ends is to spray it first into your hand and then apply it evenly in the hair with your fingers. The scent is mild and pleasant and after blow-drying it’s almost completely disappeared. Together with the fact that Maria Nila Cream Heat Spray is economical and gives nice smooth results, this makes it a good product despite the price.

12. GHD Heat Protect Spray

Very easy to apply to both wet and dry hair

Formula: Spray Format: Spray bottle Price class: Medium

GHD Style Heat Protection Spray 120ml

GHD Heat Protect Spray has a very light and thin formula. The spray bottle makes it easy to apply the product in a thin layer over the hair. It gives off a lovely, hairdresser-inspired scent and both the scent and the packaging feel very luxurious. But the spray doesn’t help much in terms of softening, so it’s not much use for detangling your hair. Nor does it help to keep the strands separate during blow drying. And unfortunately the result is neither shiny nor smooth.

After blow-drying, your hair will be light and airy. And there’s pretty much no indication that you've applied a heat protector. This means this is a good choice if you want to use several other styling products and only want heat protection. It’s also useful that the spray works for something other than styling and blow-drying. Lots of heat protectors with a greasier, cream consistency can be difficult to use after a shower when you only want to run a straightener through your hair. But GHD Heat Protect Spray is perfect for this. It’s easy to apply even in dry hair without giving an impression of heaviness. It’s perhaps not the most nourishing and strengthening product in the world, but to prevent damage and protect against heat, GHD Heat Protect Spray is a very good option.

13. Matrix Style Link Buffer Thermal Spray

Economical, with good consistency that counteracts frizz

Formula: Spray Format: Spray bottle

Matrix Style Link Heat Buffer Thermal Styling Spray 250ml

If you're looking for a heat protector that can be combined with other products, Style Link Buffer Thermal Spray is a good choice. The consistency is somewhere between a cream and a spray, and it's easy to apply and adds no structure to the hair. The scent is relatively mild, so even though it stays after application you can combine this spray with other products.

This heat protector doesn’t help you detangle the hair, so it’s best to brush your hair before applying it. Unfortunately it doesn’t particularly help to keep the strands separate while you're blow-drying it either. It works well on frizziness but doesn’t make your hair shiny or lustrous. If the ends of your hair need a bit of extra care to make them look healthy, we recommend you look for a more nourishing product. But the thin formula makes it easy to get the right amount and you aren’t likely to apply too much. The heat protector succeeds in the balancing act of making sure your hair doesn’t feel heavy or greasy but is kept airy and fresh both on the first and second days. So if you’re mainly looking for protection against heat, Matrix Style Link Buffer Thermal Spray is a good value product that lasts a long time.

14. Björk Skydda

Heat protector that smells good and has stylish, environmentally friendly packaging

Formula: Liquid Format: Plastic spray bottle Price class: Medium

Björk Skydda 150ml

This is a heat protector for the environmentally conscious. The packaging – a stylish pink spray bottle – is made from sugar cane and is completely biodegradable. The contents are free of parabens, sulphates and colouring.

Björk Skydda is a nice-smelling spray that you can apply to both damp and dry hair before you use heated tools. The spray is rather difficult to apply evenly to the hair – if you hold the bottle too close you get far too much product in a single place, while if you hold it too far away the fine drops of spray struggle to reach your hair. This means the product is fiddly to get evenly distributed in your hair and not particularly economical.

Compared with other heat protectors, Björk Skydda doesn’t leave your hair with the same shine or softness, but the scent is nice and lasts for a while. The advantage of this heat protector is that it also protects the hair against UV radiation, so it continues doing your hair good all day, not just until you switch off the hair dryer. Another positive point is that Björk Skydda is also completely vegan.

All about heat protection

Most of us probably agree that having healthy, undamaged hair is important. And yet we still do things that damage our hair, sometimes daily. Because your hair really doesn’t like heat from your hairdryer, straightener or styling tools. Fortunately there are loads of products that can help you protect and care for your hair.

You often apply heat protection as the first product after washing your hair, and after that it can be combined with other styling products. There are also many products that have several properties including heat protection. For example, hair oils generally provide protection. Even though the products are often intended to be applied to damp hair, for example before using a hair dryer, some of them can also be used in dry hair. If you don’t wash your hair every day but you use straightness, for example, it can be a good idea to pick a product that also works in dry hair. The aim is to give your hair as much protection as possible. But if you do apply heat protection to dry hair, it’s important to allow it to dry completely before you start using your styling tools. Otherwise you end up doing what’s known as “Spray and Bake”, where your hair can actually be burned by the hot tools in contact with the chemicals in the heat protection.

As well as protecting your hair against heat, these products usually help the hair to dry more quickly so you don’t need to use the hair dryer for as long. They also usually counteract frizziness and give your hair lustre. When you blow-dry your hair, there’s a risk that it will tangle. And untangling your hair also causes damage. So heat protectors often have a softening effect on the hair, making sure the strands remain separate for a smooth result.

Perhaps you’re wondering why you should blow-dry your hair at all? It should be better to leave it to dry by itself. But actually that’s not the case. When the hair strands are wet, they expand and become more porous and easier to damage. So it’s good to dry your hair as quickly as possible. Which means low heat on the hair dryer together with a good heat protector is a winning recipe for healthier hair!
