Best Hair Straightener for Damaged Hair
NITION Professional Hair Straightener Argan Oil
What is the best hair straightener for damaged hair? In general you want to look for ceramic flat irons as they often heat more consistently and don’t reach the high heat you get with titanium or tourmaline. That being said, Nition Straightener goes one step further as it combines numerous materials together for their natural benefits and to make this the best flat iron for damaged hair.
What makes this so good for damaged hair? First of all, the plates are ceramic, but they also include nano silver ions to protect your hair, and both titanium for faster heating and tourmaline for negative ions and consistent heat. Remember though, the plates are coated in ceramic, so your hair is safe. On top of that, the plates are infused with argan oil for even more protection while supplementing your hair.
Whether your hair is damaged, sensitive, or you’re just worried about using too much heat, this goes above and beyond to keep your hair safe. Plus, it has six precise temperature settings to ensure the flat iron is as high (or low) as you want.
Best Hair Straightener for Thin Hair
CHI Original Ceramic Hair Straightening Flat Iron
Which hair straightener is best for thin hair? In general we would say that ceramic is the best (much like with damaged hair) because it doesn’t get too hot. Plus, ceramic delivers consistent heat without damaging your follicles. Chi flat irons are fantastic and are easily among the best in this area.
Made to emulate professional salon stylers, these flat irons have large ceramic plates that effortlessly glide through your hair while styling and curling. From giving you silky smooth hair to letting you make the latest styles, this straightener is perfect for thin hair.
When to Use Hair Straightener?
It is best to use straighteners once your hair is completely dry, but you can also do it when your hair is 80-90% dry if you’re in a hurry. Wet hair and flat irons don’t mix well. This can cause damage like significant frizz, burning your hair, or even breakage. Some have even found that their hair is brittle after doing this too often.
When Should You Replace a Hair Straightener?
You’ll find that flat irons often last around 500-1,000 hours of continual use. This is roughly around 2-3 years. You can maximize that time by using a heatproof case that protects it and keeps it from harm and dangerous particles like dust and dry skin.
What does an old or damaged straightener act like? You’ll find that these models have plates that scrape together, your hair will snag, it might have a weird smell like burning hair, it’ll take forever to straighten your hair, and the temperature might be less consistent.
Can You Bring a Hair Straightener on a Plane?
Are hair straighteners allowed in carry on luggage? In most cases the answer is yes, but it depends on how the model is powered. The vast majority of flat irons are electric and use cords. If that describes your straightener, then yes, you can add it to your carry on luggage.
However, cordless models are a little different. Those with batteries or gas cartridges cannot be brought onto a plane, at least not as carry on luggage. Be sure to check prohibited items for more information.
How to Straighten Hair Without a Straightener?
Flat irons are the most accurate, efficient, and rapid ways to straighten your hair, but there are ways to get straight hair without any heat. Keep in mind that these methods may not work, often require more effort, and you have less control over the results.
Blow drying your hair with cold air can help your hair relax and sit straight. Wrapping or using plastic rollers can also be beneficial, but make sure you choose the right rollers so that you don’t get curls. Some people find that sleeping with their hair wet can help, but you have to set your hair or it’ll come out in weird angles.
Honestly it’s just easy to use a flat iron.
Which Hair Straightener is Least Damaging?
We mentioned this above in our reviews, but we found that ceramic hair straighteners are usually the least damaging and are best for damaged hair. At the same time, titanium models tend to be more resistant to high heat, which can make it less damaging if you often set the temperature quite high.
Can Hair Straightener Kill Lice?
Can hair straightener kill lice eggs? Yes and no. Let us explain. The truth is that lice, nits, and lice eggs are unable to live through high heat. Their threshold is around 113°F (45°C). Every model reaches above this temperature, which means that any lice or eggs in your hair strands will die.
However, let’s consider where lice are usually found. While some are in the hair strands themselves, the vast majority are closer to your scalp. This means that the flat iron won’t touch them, and even trying might cause you to burn your scalp.
How Hair Straightener Works?
Before talking about how a flat iron works, it’s important that you understand how your hair is formed on an atomic level. Your hair is composed of keratin and sulfur atoms. These are bound together and create disulphide bonds. This bond and the keratin molecules themselves are arranged in a way that gives shape to your hair.
Passing a high heat source over your hair breaks down these bonds, which makes your hair more flexible. As the hair cools, the bonds reform, but in the new position. This is why you can easily style your hair once it’s hot.
As you likely know, this isn’t a permanent change. Why does your hair go back to normal? Your hair will absorb moisture, either from the air or a shower, which will cause your hair to go back to its natural shape. This is why you need to use an iron on a daily basis.
What Hair Straightener Do Salons Use?
Hairstylists use all three major types of straighteners. Some use ceramic to keep hair safe, others use titanium for its fast and consistent heating while others still use tourmaline for its fast heating and negative ions.
It really depends on the stylist and the hair they are working with. If your hair is damaged or weak, then they’ll likely use a ceramic model. For those who have strong and thick hair, then tourmaline or titanium is more common.
Titanium tends to be faster and more consistent, but the negative ions from tourmaline can make your hair straighter for longer. Another benefit of titanium is that it lasts longer as tourmaline is more likely to break down from use.
Why Ionic Hair Straightener?
Both ceramic and tourmaline straighteners naturally release ions (also called negative ions, both are functionally the same on marketing). These are able to straighten your hair somewhat better, but the most important advantage is that they reduce frizz and make your hair shinier with each pass.
You can also get this with titanium models, just make sure to check for it. They may need some inclusions to get this benefit, but you’ll still get all the benefits from titanium as well.
Are Hair Straightener Plates Supposed to Touch?
You probably notice that most straighteners, especially premium ones, are built so that there is a gap between the plates. This gap is small, so you can squeeze them together if you really want to, but there should be a small gap between them. The plates touching can cause some extra wear and damage, but it’s not bad if it happens every now and then.
Good flat irons should provide enough heat so that your hair straightens without having to push the plates together. If you find yourself not getting enough heat, then you might need a new model.
