Best Heat Protectants For Your Hair [Review] in 2021
written by nail expert Jess Rowley
Has your hair seen better days, and you’re looking for ways to restore your luscious locks to their former glory? The dullness and dehydration caused by heat damage are the worst.
What if I told you there was a way to prevent the damage without having to give up your beloved hair dryer or flat iron.
Whether you color your hair, frequently style it, or sit out in the sun for long periods, it takes a toll on our hair strands without protection, causing them to become dry and even split, but with the right thermal protection, you can prevent this!
Think of it like this; you wouldn’t put a 200-degree flat iron directly on your skin; it would burn and most definitely damage your skin; the same concept goes for using it on your hair without any form of heat protection– it’s like sunscreen for your hair.
But don’t worry, I’m here to help.
To make things easier for you, I have spent hours hunting down the very best thermal protectant sprays and heat protectants to refresh your hair and keep it looking shiny, soft, strong, and healthy even after styling it every day.
Here’s a pro tip– while getting a heat protection spray won’t magically fix your split ends, you’ll need the chop for that, but it will protect it for years to come; once you’ve done the chopped, your hair will look like new– prevention is better than a cure after all.
You won’t want to miss my top picks!

Best Heat Protectant For Hair- A Buyer's Guide:
We all want to say goodbye to frizzy, dry ends and dull hair, and we can finally do that with heat protection. Looking after our hair is just as important as looking after our skin and health; it deserves some TLC.
Whether you’ve color-treated your hair, used excessive heat over the years, or just looking for ways to look after your luscious locks choosing the right treatment and protection is a good start.
But using heat protection spray after years of abuse and excessive exposure to heat won’t just magically fix your hair; after all, it isn’t a miracle worker, sorry to say it, but no conditioner, treatment, or heat protection will fix damaged, broken hair.
That’s when it’s time to do the chop; your hair will thank you for it. Prevention is always better than a cure; keeping your hair protected before you apply the heat is much better than trying to save it after all the damage is done– it’s not going to work.
So you have slightly dry hair but not damaged beyond repair, and you’re looking to nourish the ends with a well-deserved heat protectant; what should you look for? I’m here to break down everything you need to know to make the most out of your product.
Let’s get down to business, ladies!
Things To Consider When Buying A Heat Protectant
Right, let’s get down to the nitty-gritty details of everything you should be looking for when on the hunt for the right thermal protectant for you.
You may have heard of this in your skincare products, but humectants are used in haircare, too; they are the hydrating ingredient that attracts moisture, and they’re super beneficial for hydrating your hair.
They’re extremely beneficial in heat protectants as it draws in and locks in moisture leaving the hair feeling hydrated rather than dry and brittle, caused by excessive heat. Moisturized hair is healthy hair.
You’ll notice in hair care products that the main ingredients are glycol, panthenol, and keratin. These works to strengthen the bonds up the hair shaft and preserve moisture and prevent frizz. Ingredients like aloe vera are also brilliant in protecting hair from heat.
Along with humectants to retain moisture in your hair, many heat protectants use strengthening ingredients to add an extra layer of defense against heat damage caused by styling your hair.
You’ll notice ingredients like keratin other amino acids such as wheat protein when you see strengthening formulas.
Styling your hair isn’t the only thing that causes heat damage and drys out your hair. Excessive sun exposure without any protection on your hair is another culprit to hair damage; it is a similar concept to going outside all day on a scorching summer’s day without any sunscreen.
Your hair gets damaged in a similar way to how your skin gets sunburnt; now, while you may not feel it like you would a sunburn, it causes more damage than you may think. If you’re outside a lot, I would recommend going for a heat protectant with UV protection.
Frizz and humidity protection:
Do you live in a humid climate like Florida and suffer from frizz whenever you go out, even when you style your hair? Well, some heat protectants are clinically proven to tame frizz; they protect your hair from heat and humidity.
There’s nothing worse than spending 2 hours styling your hair for you to go outside, and it turns into frizz within a matter of minutes; not only have you damaged your hair for nothing, but it ruins your whole mood.
I have selected some excellent options for maintaining frizz as well as offering insane levels of heat protection in my list above– you can finally enjoy your hair, no matter the weather.
Frequently asked Questions
How do heat protectants work?
Heat protectants act as a barrier between your styling tool and your hair; they work by sealing in moisture and fending off frizz. They smooth the cuticle and provide a coat to protect from heat and leave it feeling soft.
They’re like the sunscreen for your hair; you wouldn’t sit outside all day in the scorching summer sun with no sunscreen on, you’d come home a crisp by the end of it, and the same goes for your hair, heat strips the shine, moisture and causes breakage.
Check out how heat protectants work and whether you really need them here.
Do you really need heat protectant spray?
Yes absolutely, whether you’re exposing your locks to high or low heat, having the right heat protection is super important as it not only protects your hair from the heat but also prevents breakage, dryness, dullness, and brittleness caused by styling your hair.
You may have gone years of exposing your hair to heat, whether that’s blow-drying your hair every day or using the flat iron or curling wand, and may finally decide to use a heat protectant, but after prolonged heat exposure, your hair is beyond repair.
Heat protection is the best way to prevent heat damage, but it will never be the cure; it will never magically seal your split ends. The best way to cure split ends is to brave the chop; without using it, you’re exposing your hair to unnecessary damage.
How long does heat protectant last when applied?
While you should style your hair soon after applying heat protectant, your heat protectant will benefit and protect your hair for 4 hours, so don’t worry too much if something comes up after applying.
Some UV protectant sprays will last you a full day of protection when out in the sun. Still, for thermal protection against styling, I would reccomend styling your hair shortly after applying heat protection to get the most benefit from it.
How do you use heat protectant spray?
The best way to use heat protectant spray is to apply the spray on dry or damp hair before styling your hair. You should apply on the mid-lengths and ends but try to avoid the scalp the best you can.
Once you’ve sprayed the heat protectant spray, then you should comb it through your hair to make sure the product is spread evenly, and you don’t miss any patches.
Check out my guide of how to use heat protection spray here— it even includes everything you need to know about heat protection spray too!
So there you have it, my friends, my top picks of the best heat protectants to keep your hair feeling refreshed, hydrated, and silky soft without having to give up your styling wand or flat iron.
Adding something as simple as a heat protectant to your hair care routine will transform your luscious locks; you’ll notice that your needs will feel less dry and brittle, and your hair will brighten.
The best way to make your heat protection spray or cream most effective is to chop off all the split ends and damaged parts of your hair and start with fresh hair; preventing heat damage is better than trying to resolve it.
You’ll notice a massive difference even after a few uses!
