Do Hair Straighteners Damage Your Hair?

The truth is that hair straighteners can damage your hair if you don’t take important steps to protect your locks first. From finding a good temperature for straightening hair to finding ways to straighten hair without heat, there are several things you can do to find out how not to damage your hair when straightening.

Do you hear a sizzle? If this is a familiar noise when straightening your hair, it means your hair is too wet. By extension, if you are wondering, “can we use a straightener on wet hair” the answer is simple – absolutely not!

Straightening wet hair causes the moisture in your strands to boil and blister the hair’s cuticle (ouch!). This leads to damaged hair after straightening, which shows as breakage and split ends.

Sometimes the damage isn’t super extreme or obvious, like breakage. It can be more subtle, like your hair looking dull or frizz that slowly starts to get worse and worse. Either way, this is enough reason not to use a straightener on wet hair.

The high heat from a straightener can also damage hair because it dries out the hair’s cuticle.

If you start noticing and staying on top of it, your hair could be fine.

But if you notice and ignore it (cos who wants to give up their straightener, right?), it could lead to damaging the inner layer of the hair, called the cortex, which means your hair will find it harder to cope with breakage, colouring, or heat styling in the future. See why it is crucial to find a good temperature for straightening hair?

Can We Use Straighteners on Wet Hair?

Let’s look at this more closely as we think about ways not to damage your hair when straightening. It saves time and fuss, but can we use straighteners on wet hair? 

Well, yes, if you insist. It will give you dry, straight hair, but at what cost?

By squashing your hair between super-hot plates that dry and shape your hair, you are likely doing levels of damage that will take a considerable amount of TLC to fix.

To prevent frying your cuticles and stripping all the moisture from your locks, think about straightening your hair by blow-drying.

Pile on the heat protectant and gradually work your way through sections of your hair with a heated appliance that is a safe distance from your precious cuticles.

While this isn’t the same as using straighteners on wet hair, it will undoubtedly provide a straightened look, all while maintaining the condition of your hair in the process.

How to Not Damage Your Hair When Straightening

Now that we have dispensed with the flat iron-wet hair conundrum, let’s look at ways to learn how not to damage your hair when straightening. Here are a few simple steps to keep you on the right track:

  • Avoid the dreaded sizzle and ensure your hair is properly dry before using hot tools like hair straighteners

  • After blow-drying or letting your hair dry naturally without heat, apply a heat protectant to ward off damage from high temperatures

  • Lastly, add a hair care product, such as a thick creamy hair mask, like Kérastase Résistance Thérapiste Masque, to nourish the hair and help prevent further damage

When you follow these three steps, you can be sure to enjoy long-lasting, lush, straightened locks. 

What is a Good Temperature for Straightening Hair?

Part of knowing how to not damage your hair when straightening is understanding your hair texture and finding the right heat level for you.

That said, finding a good temperature for straightening hair can be tricky. Most experts agree that the ideal range is between 250 and 375 degrees Fahrenheit ( or 120 to 190 degrees Celsius), naturally depending on the thickness of one’s hair.

Those with finer hair should drop to lower temperatures, whereas higher temps may be required for coarser textures. 

Again, using a heat protectant is essential when experimenting to find a good temperature for straightening hair, as it helps create a look you love without unnecessary damage.

Remember, there are ways to straighten hair without heat, from leaving it to dry naturally to using cool settings on your blow-dryer.

How Often Should You Straighten Hair?

We always get asked, ‘Do hair straighteners damage your hair?’ or ‘is there a straightener that doesn’t damage hair?’. The inevitable follow-up question is, ‘How often can I straighten my hair without damaging it?’

We’re gonna tell it to you straight. Unless you won the genetic lottery and have damage-proof hair, excessive straightening always results in some form of damaged hair after straightening. So, simply put – does straightening your hair damage it? Yes.

If, like many people, you tend to over-wash your hair, you have to straighten your locks every morning.

This cycle of dependency is something to avoid. If you’re wondering, ‘How often can I straighten my hair without damaging it?’, we have a few thoughts to keep in mind.

Regarding how often you should straighten your hair, ideally, you’d be washing and straightening your hair every other day. Try to give your hair some days off from the shampoo and straightener.

If that sounds like a nightmare for you, instead of washing your hair, freshen your strands with a dry shampoo to see you through. After all, knowing how to not damage your hair when straightening becomes a lot easier when you take the straightening out of the equation!

If you simply *cannot* skip a day of straightening, ensure you do so no more than once per day. And never use other heated stylers on the same day. (We’ll give you a pass if you’re rocking the red carpet!)

A key tip on not damaging your hair when straightening is to straighten small sections of hair at a time. It can be tempting to try big sections at a time to straighten your hair faster, particularly if you are time-poor and often straighten your hair, but it’s inefficient as the iron can’t get to all your strands.

We know this sounds like a minor tip, but using small sections ensures that you swipe each strand only once with your flat iron, reducing potential damage. If you are wondering how often you should straighten your hair because you need to go over your hair many times, there’s an issue. It could be that:

●  the hair straightener isn’t suitable for your hair type

●  you’re applying too little heat

●  the sections of hair are too large

After putting so much effort into your cute coif, it’s essential to preserve your style. Resist the urge to put your hair in a ponytail or bun overnight (think bumps and creases).

Instead, opt for a silk scarf to cover and protect your straightened tresses. We're in love with the Silke London Hair Wrap
