Buyer’s Guide for Professional Flat Iron 

Buying a flat iron, especially a professional one does not only rest on knowing the existence, the beauty, and technical features. The bigger issue is how to differentiate the good one from the bad ones, depending on the texture, type of hair you have. Many professional flat iron reviews, however, seem not to address these issues, after all, they are just looking at ways to get their products sold.

When you find yourself in this kind of market – where reviewers just want to talk about the product and the good things it offers, in a bid for selling without paying attention to you, the consumer, the likelihood of you going for a bad flat iron is very high.

That’s why we’ve taken our time to comb the market, taking into consideration the materials, the technical features, and your hair type, to bring you nothing but the best of reviews and the things you need to take into consideration before you buy any flat iron, anywhere.

The Type of Flat Iron to Go For

Satisfying the needs of your hair should always be at the center of your choice when selecting a flat iron. If you want to professionally styled hair or you are thinking of carrying the salon experience home, you should carefully think about the type of flat iron to go for – ceramic, tourmaline, and titanium.

Types of flat irons

1. Ceramic Flat Irons

2. Tourmaline Flat Irons

3. Titanium Flat Irons

4. Ionic Flat Irons

Ceramic Flat Irons
Some 20 years back ceramic hair straighteners were introduced onto the flat iron market. Since then, they’ve become an important part of what makes the best professional flat iron. Ceramic is known for its fast heat up time.

Though it’s affordable when compared to other flat irons, ceramic flat irons still provide the splendid functionality you would need in any good flat iron. Many ceramic straighteners come with ionic technology, the technology that is capable of producing negatively charged ions. Apart from neutralizing the positive ones to help prevent cuticles on the hair, negative ions help ensure an even distribution of heat during hair styling.

Ceramic flat irons also make use of smooth plates, which are known for their quick heat up time, ensuring easy and fast straightening of hair. There exist differences in the ceramic flat irons as well. There are those that come with complete ceramic metals. Others, however, come in different metals but coated with ceramic.

Whichever the case may be, the inclusion of ceramic to a hair straightener ensures consistency and an even heat and temperature distribution during hair styling, it also gives you a whole lot of temperature options when straightening, and in the end, ensures a frizz-free hair with all the salon quality experience added.

Tourmaline Flat Irons
Tourmaline straighteners are widely known and used among beauticians, hair stylists, and amateurs. There’s one thing that it’s known for – it is touted as the least damaging flat iron among all the flat irons.

Note, however, many flat irons come in ceramic metals and then coated with tourmaline instead of ceramic again. One good thing about this is that whiles the ceramic is working on the even and consistent distribution of heat, the tourmaline coating will ensure that the styling is done fast, allowing the straightener to smoothly slip through the hair to prevent damage to hot spots. It also helps prevent repeated hair drying after styling.

Additionally, tourmaline flat irons activate negative ions, helping a great deal when it comes to producing frizz free hair. Tourmaline coated flat irons are known to be the most durable. As such, most of them are expensive, however, for those who want quality, professional hair, they always go for this type of flat irons.

Also, flat irons that are coated with tourmaline are somehow immune to heat loss, something other flat irons suffer from. Apart from reducing hair damage, cuticles, and creating smooth hair, tourmaline coated straighteners are good for producing salon quality hair.

Titanium Flat Irons
Titanium flat Irons entered the styling market late though, but they are known to be the most innovative in terms of modern technology and meeting the needs of the modern hair. Scientists realized that titanium is one of the best heat conductors, and as such, used it to produce a coating for flat irons, a coating that is known to style any hair type, anytime, under any temperature condition.

Also, titanium has a fast heat up time, lightweight, and ensures flatness when straightening hair. With this type of straightener, the damage caused by too much heat is reduced. Titanium is also a negative conductor of heat, ensuring easy distribution of temperature.

All in all, titanium coated flat irons are capable of producing incredibly styled hair. They are durable, lightweight, and efficient in transforming your hair from crap to success. Most of the top professional flat irons you’ll come across are made with or have titanium elements in them.

Ionic Flat Irons
Well, maybe you’ve always known that the only hair straighteners on the market are ceramic, tourmaline, and titanium. Ionic flat irons are also very good and among the latest technology to enter the hair straightening market.

Some of the most technologically-oriented and top performing flat irons have a little bit off or completely ionic technology. This technology, though not used to fully produce flat irons as in the case of ceramic, when included in straighteners, adds a layer of protection, beautification, and health to your hair.

Choosing a flat iron – Taking the type of hair into consideration
Though the various models in terms of technology and material matter – like ceramic, titanium, tourmaline, and ionic, one important factor is the type of hair you are carrying and the kind of effect you are looking for in your styling – wavy, curly, or flips.

It’s not just about ceramic or titanium. Titanium can be the best and technologically good flat iron, but if it’s not good for your hair, you won’t have the right experience, leading to long-term hair issues. The following are the hair outcomes or types to consider and the type of technology or material to go for.

Types of hair

1. Straight hair

2. Wavy hair

3. Curly hair

Straight hair

The straight hair is known to be very resilient, it’s difficult to damage and at the same time difficult to curl. It is the oiliest among the different hair textures because the sebaceous glands emit sebum, which is capable of producing some curls naturally though.

However, to get flawless, professional, and naturally curled straight hair, it’s good to go for flat irons that come with temperatures of between 250 and 450 degrees Fahrenheit. However, adjusting the temperature to be either 200 or 300 degrees Fahrenheit when styling is ideal and good. Don’t go further. And with that, the Karmin G3 Salon Professional Ceramic Flat Iron would do just fine.

Wavy Hair

Wavy hair – one important thing to know about this type is that it’s neither curly or straight, and more susceptible to frizz. In these situations, you should look at having a multi-purpose flat iron. One that can straighten and at the same time curl your hair or give waves.

Titanium flat irons are known to be good conductors of heat, have short heating times, and come with many temperature options, so it’s good, in this situation, to go for a titanium coated straightener.

And since we are talking about heat conduction, temperature options, and fast heat up time, the BaBylissPRO Nano Titanium-Plated Straightening Iron is a perfect tool that has all it takes to give you curly, wavy and straightened hair at the same time.

Curly Hair

Some people naturally have curly hair. Some use flat irons to curling theirs. All curly hair, either from a flat iron or natural all comes down to one thing – they are extremely difficult to maintain. So if care is not taken, one night is enough, and your hard earned curled hair is gone – just like that.

When you have a curly hair but find it difficult to maintain or you just want to have a curly hair, then your best bet is a tourmaline flat iron. Curly hair is prone to damage. It is also known as the most temperamental in all the hair types.

Tourmaline is widely known to be technologically innovative and brings cutting-edge ways of solving the most difficult curly hair issues. As such, the best tourmaline flat iron that can handle this job is exactly the RUSK Engineering CTC Technology Professional Straight Iron.

Other specific specs to consider when buying a flat iron
The flat iron market is choked. A little mistake and you will have to suffer from a particular straightener for a long time until you have enough money to change. Meaning you should be vigilant when shopping for hair straighteners – every spec must be checked to the last drop.

The plate size

When shopping for hair straighteners you will always come across different plate sizes. Some with 1-inch plate sizes. Others are 1.5 or 2 inches long. Always remember that if you have a fine, thick hair, is advisable to choose 1 or 1.25 inches flat iron.

The Temperature

Temperature plays an important role in determining the goodness of a flat iron towards straightening hair. Optimally, the temperature for many straighteners falls between 200 and 450 degrees Fahrenheit. Too little of everything is not good and they say too much meat in soup does not spoil the soup, but I guess if you use the soup principle here, you’ll be roasting your hair and not straightening it.

A temperature less than 200 degrees might not achieve a good outcome. In the same vein, a temperature above 410 degrees might be too much, just equal to roasting meat. Always play safe and choose something moderate.

The heat up time

One important thing about heat up time is that it determines the difference between you getting to work late or early because of your flat iron. You switch on a flat iron and would have to wait for 5 minutes before it heats up. That’s totally bad.

So always go for flat irons with faster heat up time. Some have 15 seconds heat up time, others have 30 seconds heat up time and so on. Always remember that with heat-up time, the lesser the seconds a flat iron takes to heat, the better for you.

The voltage

You are in the US and all of a sudden you decide to travel to Germany. Do you send your hair straightener or leave it and buy another one when you get to your destination? Well, buying a new one is just a waste of money.

But with some straighteners, you still have to buy a new one anytime you are traveling – those are single voltage flat irons. They are not good for the avid traveler.

When buying a flat iron, always choose the one with double voltage. You can move with them wherever you go. No matter the country you find yourself, your straightener would always be your friend, having no fear of electricity in any country.
