Frequently Asked Questions on Curling Irons and Hair Damage

Can curling your hair damage it?

This is perhaps the single most important question in your mind right now. It's not the "curling" that damages your hair, but the heat.

Heat styling can damage your hair if you do it regularly, and without adequate protection. It's important to use a heat protectant before using any heat styling tools. And to give your hair a break. Deep condition your hair and use a hair mask at least once a week.

Is it bad to curl your hair every day?

We love to look great every day. Some of us may even want to have curly hair every single day. But if that comes at the expense of our hair health, then we might have to take a closer look.

It's NOT bad to curl hair every day. But daily heat styling can have permanent irreversible effects on your hair. This is why it's important to give your hair a break. You can try experimenting with no-heat curls or second day hair. Even washing your hair everyday is not good.

Are ceramic curling irons better for your hair?

Any heat styling tool you use on your hair has the potential to cause damage to your delicate strands. Ceramic is a good option to help prevent some of that damage, and leave your hair healthier.

A ceramic barrel emits negative ions into your hair when you are using it. These ions work to close your hair cuticle which protects it from damage and helps it to retain moisture. This also keeps your curls from being frizzy or full of static. A material like metal will have the opposite effect on your individual strands.  A metal curling iron barrel will force open your hair cuticles, robbing them of moisture and exposing them to all kids of heat damage.

The surface of a ceramic curling iron is very smooth and won't collect dust or debris like metal barrels do. Ceramic cleans easily, so you can regularly remove residue from your styling products. This allows even heating of your barrel and prevents the hot spots that can fry your strands.

Ceramic is also very lightweight compared to other curling iron materials. Remove stress from your arms and wrists with a ceramic barrel curling iron.

Is ceramic or titanium better for hair?

Titanium is another great material to look for when shopping for your next curling iron. Is it better than ceramic? Let's look.

Like ceramic, titanium does emit negative ions in to the hair shaft to close your cuticle and protect it from damage and moisture loss. Titanium curling irons work using infrared technology, which is huge for women with especially thick or coarse hair.

This technology tends to transfer heat much faster than ceramic, so thin haired girls need to use it with caution.

It's still great for more fragile hair, you just need to watch the heat settings to prevent frying your strands.

Titanium is another super smooth surface material. It won't collect fuzz and dust that can be transferred to your hair during styling. It is also very easy to clean, so there's no reason to fight with product build up that pulls, sticks to, and ultimately harms your hair.

Another lightweight product, titanium eases the stress hair curling can have on your body. Old metal curling irons can be heavy, clunky, and hard to manipulate around your head. Using a lighter styling tool will make your style go faster and help you keep yourself from burns.

One of the biggest differences between ceramic and titanium curling irons comes down to price point. Titanium styling tools are most often quite a bit more expensive than ceramic ones. While the added investment may be well worth it for girls with unruly, thick strands, those with thinner, shorter hair could save a few bucks and still enjoy the benefits of using a ceramic based curling iron.

Now that we know a bit more about surface type, let’s check out a few of my favorite curling irons that won’t damage your hair.

Top 5 Picks: Curling irons that won't damage hair

1. T3 SinglePass Curl 1.25 Inch Professional Curling Iron

At the higher end of the price range is the T3 SinglePass Curl Professional Curling Iron, with a few really cool features.

So which is the best curling iron for damaged hair?

Any of those products mentioned above is good for damaged hair since they all have features that prevent heat damage.

The key here is to use the lowest heat setting possible, so get a model that offers the lowest temperature.

And if you can go for a few days or weeks without heat styling your hair, then that’s even better. Sometimes, hair can get too damaged that you’ll have no choice but to grow it out and cut it. I hope this is not the case for you.

How to prevent further heat damage

With heat settings up to 450 degrees, it's important to protect your hair from the damaging effects of using curling irons for your style. There are a few steps you can take to protect your hair from your heat tools and prevent damage.

1. Dry hair thoroughly

First, always make sure your hair is dry before using a curling iron to style it.  Even the safer materials like ceramic and titanium have the potential to fry your hair if it’s damp.  Starting with dry, clean hair will give you the safest results when using any curling iron.

2. Use the right heat setting for your hair type

Second, make sure the heat setting you are using is right for your hair. If you have thin, delicate strands, using the highest setting on your curling iron is unnecessary and dangerous for your hair. Long, thick hair tolerates higher temperatures much better.

Start with the lowest setting possible and test a few curls. You can still create an awesome look without hellfire heat.

3. Use a quality heat protectant

Third, use high quality heat styling products. Spraying your hair with a heat protector like this one that includes Argan oil will coat your strands before you add heat, providing a protective barrier between your hair and curling iron. Heat protectant serums and sprays have added benefits like preventing frizz and adding shine to your finished style.

4. Take a day off from heat styling

Finally, give your hair a break. It's good to have a go-to 'do, but make sure you let your hair rest, too. Try and take a day off from any kind of heat styling, including blow-drying. Use a repairing mask to add moisture back to your hair and seal open shafts.

Give your hair as many heat-free days as possible to have strands that are fresh, not fried.

Buying a new curling iron really is a big commitment. Check out the ones I've reviewed here, and make sure you read reviews and look for the one with the best features for your hair. You'll be glad you did a little research, and your hair will love you back with high shine and a healthy look.
