How to Choose the Best Flat Iron? Buyer’s Guide
There are plenty of flat irons but their quality and features vary. This makes many users wonder what is the best flat iron? Well, to help you find the right flat iron for your hair type, we have structured this buying guide so that you can choose more confidently.
Know Your Hair Type
First and foremost, you need to know exactly what’s your hair type? Whether it’s thick, curly, or fine. Knowing your hair type will help you understand how much heat you need for straightening your hair. Plus, the majority of the manufacturers indicate that their flat iron is designed for which type of hair. Thus, knowing your hair type let you choose your hair straightener wisely.
Fixed Vs Adjustable Heat Settings
Some flat irons come with fixed heat while other offer variables heat settings. If your straightening iron has fixed heat settings, you are limited to the default temperature, and you can’t alter it. If you are certain that the default temperature is ideal for your hair then there’s no issue in picking a flat iron with fixed heat settings. However, for many users it won’t work so they should opt for a flat iron with adjustable heat settings.
Flat irons with variable temperature settings allow you to adjust the heat exactly to your hair type. Usually, these irons have 5 or 3 level-dials, or some are digital which you can set to any requested temperature. Digital hair straighteners come with buttons for adjusting temperature and the set temperature is shown on the LED display. Most hairstylists and professionals prefer the best flat iron with adjustable heat settings.
Plate Material & Heating Technology
Most of the flat irons’ plates are made up of ceramic, tourmaline and titanium, and their heating technologies are different. The above three are the best material as they evenly distribute heat to reduce damage. At the same time, they emit negative ions to reduce frizz. Let’s discuss each material a bit in detail:
Ceramic material has lower thermal conductivity than metal and it’s corrosion-resistant. Cheap flat irons have a very thin layer of ceramic on the plates thus you have to pass it multiple times on your strands. But the best hair straightener has numerous layers of ceramic on the plates for healthy straightening results. The best part of ceramic flat irons is that they conduct heat evenly and treat each and every strand in the same way. As a result, the damage caused by heating tools is greatly reduced. However, a ceramic flat iron is vulnerable to crack if you drop it, so you should use it with great care.
Titanium is a metal and it’s also corrosion-resistant. But unlike ceramic, this metal is strong and the plates are durable. Also, it’s lightweight due to which titanium flat irons are light and easy to use. The titanium plates heat up very quickly which’s good as well as bad. They are good because the quick heat up gives you a fast straightening experience and saves a lot of time. But they can get very hot which increases the potential heat damage. Go for titanium flat irons only if you have thick, long, and lots of hair.
Tourmaline hair straighteners are made similar to ceramic with fine surfaces. The difference between ceramic and tourmaline is that when such plates are heated they become negatively charged ion sources. The negatively charged ions neutralize the positive ions and revive the natural shine. A combination of ceramic and tourmaline makes a perfect surface for your hair and gives you amazing results.
Nano actually means something that’s very very small and can’t be seen with naked eyes. You won’t see the nano term singly, it’s either nano-ceramic or nano-titanium. In reality, these small particles are fixed on the plates or the manufacturers use them entirely to make the iron plates. Indeed, the plates with nanomaterial work far better than the traditional plates. In addition, they prevent bacterial growth.
The infrared heating technology uses a source that emits invisible light in the infrared region for generating heat. In contrast to the traditional tools that heat the surface of the plates, these best hair straighteners 2021 work directly on your strands from the inside out. This makes the straightening experience faster and your hair is exposed to heat for a short time.
All flat irons’ plates emit negative ions upon heating but the difference is in the number of ions that they can emit. Your hair is positively charged thus it has an affinity for negative ions. So, a flat iron that generates more negative ions gives you good results and is definitely the best flat iron 2021. And when the manufacturers mention ionic with their tools, it means that it can generate a large number of negative ions.
You may know that one size isn’t perfect for all, so with all other features plate size of flat iron for hair also needs your consideration. The plate size varies from 0.5″ to 2.5″. You should choose the plate size depending upon your hair type and the style you want. For example, larger plates offer good heat but they can’t reach the roots of your hair. Also, if your hair is prone to damage, it can cause damage due to excessive heat. On the other hand, small plates straighten your hair gently and don’t cause any damage, but they take more time. Thus, if you pick the right size, it will not only protect your hair from damage but also save time. We will discuss plate size a bit more in the below section.
Select the Right Temperature
Once the heat level of the best hair straightener matched with the length and type of your hair, there will be no more damage. Keeping the length of your hair, you can select the right temperature and plate size as follows:
For short hair, always pick a flat iron with small plates (0.5-1 inch) and the temperature level depends upon your hair type. If your hair is thick, coarse, and stubborn, the ideal heat setting is 350 to 400 degrees Fahrenheit. However, if your hair is fine, thin, and fragile, operate your flat iron between 250 to 350 degrees Fahrenheit.
For long hair, go for a flat iron with large plates (1.5-2 inches) since large plates can straighten a large section of your hair simultaneously. But flat irons with large plates can be weighty and they may tire your arm soon. So, for a comfortable straightening experience, make sure that your flat iron weighs less than 2 pounds.
Dual Flat Iron for Traveling
If you travel abroad, then your normal 110V flat iron may not work everywhere because the voltage for home appliances in some countries is 220V. Hence, if you are a traveler, you should invest in the best dual voltage flat iron that works at 110V as well as 220V. Also, there are cordless flat irons that are battery operated. They are even convenient for traveling and they work great for thin, fine, and short hair. But for long and thick hair, they are not much appreciable.
Whether you have fine, thin, long, short, or thick, curly hair, here you can find one of the best flat irons. We have considered every budget and hair type, thus this guide is for each and every one of you. We have also included a buying guide for you so that you can make an informed and wise decision.
