What is a hair heat protectant spray?

Hair heat protectors are products that coat your hair with a protective layer to stop heat from damaging your hair. You apply them before using hot tools.

We all know heat from styling tools can damage your hair. Hairdryers, tongs, straighteners, curlers and wavers all use high heat temperatures to set your hairstyle.

They make you look and feel fabulous but they’re damaging your hair with every use.

Every heat styling will make your hair dry out and become brittle and prone to snapping and breaking.

Worst of all, heat damages your color.

It causes it to fade and pulls the color molecules from your hair which can wash out your hair dye color. So what can you do to protect your hair and your colour to keep it looking fabulous?

This is where heat protecting sprays come in!

The best ones will give you shine, volume and protection without weighing down your locks or leaving behind any residue.

They’re perfect for protecting coloured hair from flat irons, curling irons and wands and blow dryers so that your colour lasts longer while keeping your style intact.

How to use a heat protection spray.


  • Apply to wet or dry hair and leave it to soak in before styling.
  • Spray it as evenly as possible to cover all of your hair.
  • Pay particular attention to the ends which will be older and more damaged.
  • Use as per the instructions on the bottle.


  • Don’t use straighteners or any tools other than hair dryers or hot air brushes on wet hair.
  • If you apply to dry hair, let it soak in and dry completely before styling.
  • Don’t overdo it. You can leave a sticky residue.
  • Don’t forget your roots. Your hot tools may not touch them but the sun will and good products will contain UV protection too.

Which is the best heat protectant spray?

Some contain ingredients that also condition your hair while leaving it protected. Some can feel heavy or leave a sticky residue on your hair. So you’ll need to match one to your hair type.

How to Apply : L'Incroyable Blowdry

Reviewers say:

“FABULOUS. It made my hair so much easier to dry. And have me a smooth finish and lots of volume. I tied my hair up in a top knot all day and just gave it a quick blast with a hairdryer at home. It looked almost exactly as it had after styling.”

“My hairdresser used this on me so decided to get some for myself and was so so pleased to get the same great results! Lots of body and adds shine.”

We say:

We love everything Kerastase here at Coloured Hair Care so we had to give this a go. It’s not the strongest contender on the list but still one of the best for frizz taming and protection.

“Brilliant for hair care.”

We say:

We weren’t sure putting oil in your hair before putting heat on it was such a good idea but a good idea it is.

Let it soak in a little before styling so that it really nourishes the tips of your hair. Smells great but too much could make your hair greasy. Best for those with really dry locks.

Heat protectant sprays FAQs

Do hair heat protectant sprays really work?

The answer is a resounding yes!

Heat protectant sprays work by creating a barrier between your hair and the heated styling tool.

This barrier protects your hair from the direct heat, which can cause all sorts of damage like split ends and frizz.

By creating a barrier between your hair and the heating element, the spray helps to prevent the moisture in your hair from evaporating.

This can lead to smoother, shinier hair with less frizz.

In addition, heat protectant sprays can help to hold your style in place, making it more resistant to humidity and fly-aways.

Can you still get heat damage with heat protectant?

In theory, no. But in reality, things are never that simple.

Just like sunscreen doesn’t make you invincible to the sun, heat protectant isn’t a guarantee that your hair won’t be damaged by heat.

However, it can help to reduce the amount of damage caused by heat styling, so it’s definitely worth using if you’re concerned about your hair health.

And remember, even if you do use heat protectant, you should still take breaks from heat styling to give your hair a chance to recover.

Do you let heat protectant dry before straightening your hair?

Like most things in life, there is no clear-cut answer!

It really depends on your individual hair type and the amount of heat you’ll be subjecting it to.

If you have fine or damaged hair, it’s probably best to err on the side of caution and let the heat protectant dry completely before starting to style.

If you have thick or frizzy hair that’s resistant to heat damage, you can probably get away with straightening it while the heat protectant is still damp.

Ultimately, it’s up to you to experiment and see what works best for your hair. So go ahead and give it a try – your perfect hairstyle awaits!

Is coconut oil a good natural hair heat protectant?

Coconut oil can definitely help to protect your hair from heat damage.

It’s a natural moisturizer, so it can help to keep your hair hydrated and healthy.

It also has antibacterial and anti-inflammatory properties, which can help to soothe your scalp and prevent irritation. And, if you use it before you style your hair, it can act as a barrier between your hair and the heat, helping to prevent damage.

So, if you’re looking for a natural heat protectant, coconut oil is definitely worth a try.

Just be sure to use it sparingly – too much can make your hair greasy. And, as always, test it out on a small section of your hair before using it all over.

That way, you can see how your hair reacts and decide whether it’s right for you.
