TOP 7 Heat Protection Sprays for Hair [My Reviews]

Spray-on conditioners, lightweight mists, and serums – they’re currently must-haves for heat protection during heat styling routine. I tried the most popular products! What’s worth choosing?

One of the most common causes of hair damage is… frequent styling. However, the frequency isn’t the problem. High temperature we use is a wrongdoer:

  • it breaks disulfide bonds
  • it speeds up loss of moisture in hair

So, all we need to do is reduce the harmfulness of heat to avoid breakage, dullness and splitting.

If you don’t want to give up on thermal styling, then you must go for heat protectants. I recommend light-textured sprays the most because they’re easy to use – you spray the product on the hair and style worry-free.


Are you curious which of the most popular sprays are worth your attention? I’ve tried them specially for you!

1 / Nanoil Heat Protectant Spray

Listing it as the first one isn’t random – it fully deserves this. To me Nanoil is the best heat protectant spray on the market. Apart from having a luxury design and good price, it’s super effective. This weightless formula nourishes the hair and instantly protects it from heat while blow-drying, curling or flat-ironing. Plus, it creates a shield against UV rays! Nanoil Heat Protectant Spray also prevents color fading, dryness and damage. If the hair happens to get weaker, the product works by strengthening and repairing it thanks to silk proteins. The spray smells amazing and envelopes the hair without weighing it down.

Size: 200 ml

2 / Kérastase Chronologiste Thermique Régénérant

It looks similar to Nanoil because it’s also a combo of black and gold. However, the price differs and to me it’s too high, given that Kérastase Chronologiste Thermique Régénérant doesn’t display some extraordinary properties. It provides protection against heat, eases hair styling by smoothing the hair, plus prevents frizz for up to 24 hours (if it isn’t raining). One more thing: I thought I was buying a spray while after unpacking I saw it was cream…

Size: 150 ml

3 / Kemon And 13 Heat Spray

I got Kemon And 13 Heat Spray by accident and it stayed for longer. I used the whole bottle. The formula is based on ferulic acid which prevents free radical damage and is a natural sunscreen. The product ensures protection from high temperatures, reduces dryness and softens the hair. The good thing is it doesn’t overload the hair or the budget. In a competition for the best item for the safest heat styling, Kemon’s spray is among the top products.

Size: 200 ml

4 / Balmain Thermal Protection Spray

I fell for this one right off. The pink-colored liquid and a clear bottle make a lovely match! I couldn’t resist buying it though it’s one of the most costly thermal protection sprays. Balmain is known for good-quality products. This spray smells lovely, protects from heat, smooths the hair and adds shine, but I can’t agree it goes with all hair types. I think it’s good for thin and limp hair. It contains provitamin B5 and silk for strengthening.

Size: 200 ml

5 / L’Oréal Elvive Dream Lengths Heat Slayer Pre-Iron Spray

Now, a thing labeled ‘good for everyone’ – it’s second to none when it comes to price and availability. However, it doesn’t stack up well when we look at the components: it’s filled with alcohols and silicones. Added arginine and camelina oil save the formula, having a strengthening and revitalizing effect on hair. When it comes to protection, L’Oréal Elvive Dream Lengths Heat Slayer Pre-Iron Spray isn’t the best choice but it’s good to use from time to time – it prevents breakage, defines the curl and stops frizz.

Size: 150 ml

6 / Bumble and Bumble Hairdresser’s Invisible Oil Heat/UV Protective Primer

I pinned my hopes on this primer because I really like Bumble and Bumble. Sadly, I was slightly disappointed. Not by the effects because it’s good for protection from heat or the sun, plus prevents frizz and nourishes. However, it has so many oils that it leaves my hair roots greasy… If it didn’t, then I think I’d keep using it (given the competitive price).

Size: 60 ml

7 / Ouai Heat Protection Spray

I’m big on minimalist products so Ouai Heat Protection Spray is a good choice. What’s inside the simple aluminum bottle can’t be called minimalist, though. It’s 12 botanical extracts and 2 oils in a combination with panthenol and vitamin E to effectively revitalize, strengthen and beautify the hair. Naturally it also protects against heat and prevents damage while heat styling. Spritzing this light mist on hair is all you need to do.

Size: 130 ml


Have you got any favorites yet? I hope my personal round-up of heat protectant sprays will help you choose the right hair styling product so you will never say ‘flat-iron ruined my hair!’.
