1. HSI Professional Ceramic Ionic Flat Iron - Best flat iron for managing frizz
The HSI professional flat iron offers one of the best straightening experiences.
With a blend of ceramic and tourmaline-made plates, a decent heat range as well as useful add-ons such as Argan oil and a heat glove, this is an affordable and first-rate straightening solution.
It also boasts of 1-inch plates, dual voltage and a quick heating time.
Ideal Temperature Range
One feature that we liked about this flat iron is that it offers an adjustable temperature range of between 240 and 450 degrees Fahrenheit. As a result, the HSI flat iron can be used on any hair type. However, given the solid ceramic plates, it works best for people with fine or thin hair. The HSI gives full control of the heat setting, which you can adjust by pressing a button on the LCD display.
HSI professional flat iron is made using 100% pure ceramic plates, which have been infused with tourmaline material. Pure ceramic differs from most of the ceramics you would find on ordinary flat irons that are usually baked onto steel plates. The latter type is prone to chipping and cracking, generating uneven heat from the metal.
While pure ceramic is a lot more difficult to make, it confers numerous perks including improved heat diffusion and resistance to cracking, chipping or peeling. The plates are also infused with tourmaline, which, to a great extent, is the best material for flat irons. Tourmaline emits infrared heat that is considered to be safe and healthy for your hair.
The 1-inch plates also have curved edges. They are designed in this manner so as to make it easy to flip or curl your hair as you want. If you have long hair, you would prefer a wider plate. Nonetheless, the 1-inch plate is perfect for the majority of hair strengths.
The HSI professional ceramic flat iron includes a tiny bottle of Argan oil and heat gloves. The Argan oil has been proven effective in treating dry or damaged hair. The gloves provide an easy and safe way to handle the hair tool at high temperatures.

The LED temperature display is pretty easy to read. Usually, the plates can heat up to a temperature of 450 degrees Fahrenheit, which is hotter than most ceramic hair straighteners. These high temperatures result in extremely straight hair.
The plates have curved edges; hence, you can use the tool to make your hair curly or wavy.
The Babyliss Pro flat iron has an ultra-thin structure, which makes it perfect for travels since it is easy to store in small-sized spaces. What’s more, the thin build lowers its overall weight, meaning that you will experience minimal hand fatigue when running it through your hair.
At just 1-inch in width, the Babyliss pro flat iron is perfect for people with short or thin hair. The make of this straightener using nano titanium plates is advantageous in that it emits far-infrared heat, which is effective and causes no heat damage to your hair.
Also, the ceramic plates are able to distribute heat evenly and quickly, delivering up to 50 heat settings. Given the diversity of the heat settings, the flat iron is compatible with most types of hair ranging from fine to coarse hair.
Some of you avoid using flat irons because you are too scared to burn yourself. If you sail in this boat, then you will appreciate the safety features that have incorporated in the Babyliss Pro U Styler. The heat-resistant housing, cool tip and rubber-made thumb rest are not only meant to keep you safe but also make the flat iron feel comfortable when in use.
The plates also produce negative ions that help to seal in moisture into your hair. In turn, the moisture ensures that your hair stays shiny and healthy. Its capability to trap moisture is one factor that gets highlighted in multiple hair straightener reviews.

The CHI G2 weighs about 8.8 ounces. Although it is not the lightest flat iron in our review, it is the lightest one that also maintained a high-quality and durable feel. If you are always style-conscious, then you will appreciate this hair straightener’s slim, sleek structure that is complemented by a glitter finish.
It also has an LCD digital display, which you will see on the top exterior section. This display usually shows the current temperature. If you have activated the preset mode, then the display automatically adjusts its color so you can identify the temperature at a glance.

GHD Classic Styler has the smallest range of temperatures, which start from 347 to 365 degrees Fahrenheit. Although this temperature range is small, it falls in the general temperature range for most flat irons, making it suitable for majority of hair types.
However, if you have thick, coarse or curly hair, the best flat iron is one that has a higher temperature range than that of the GHD model.
We also liked the construction of the 1-inch titanium-plates, which enables them to heat consistently and uniformly.
Are you looking for a flat iron that heats up very quickly? The GHD Classic Styler 1 is your best bet, featuring a heating speed of 17 seconds. Also, the unit remains hot between passes and it feels steadily hot across the plates. However, most online reviewers reported that it took at least three passes to straighten her hair.

For less than 40$, this is among the cheapest flat irons of our list.
Featuring tourmaline-infused ceramic plates, the Conair Infiniti Pro is designed to destroy frizz and make your hair healthier and shinier.
Initially, most manufacturers used metal plates to make flat irons. With this build, it was difficult to straighten hair perfectly as the plates had a tendency to create static while also causing small hairs to fly away.
These flat irons also sapped away any moisture present in the hair shafts. Thankfully, the tourmaline material helps to lock in nutrients and moisture, rather than steaming them away.
The Conair Infiniti Pro has three size options: one inch, 1.5 inches and two inches. The 1-inch straightener is blue, the 1.5 inch one is pink and the 2-inch model is black.

This flat iron also has a quick heat time of 30 seconds. It is also very heavy weighing 11.75 ounces. For this reason, you may experience arm fatigue if you use the appliance for an extensive period.
One other feature that customers complained about involves the flat iron’s design. Contrary to other hair straighteners, its plates do not stretch from one end to another. As such, there are no rounded plate edges, meaning you can only use the flat iron for straightening.

Guide to Choosing the Best Flat Iron
It always feels slightly overwhelming, when, for whatever reason, you are in the market for a new flat iron. For every brand, there is a plethora of options to choose from, and multiple factors to consider, not forgetting the complex terminologies in the product descriptions.
No need to worry, as we are here to help. In the following sections, we will take you through the different considerations to account for when purchasing a flat iron.
First off, the metal plates on a flat iron vary in length and width. As a rule of thumb, you should pay more attention to the width than the length. With a wide plate, you can straighten a greater portion of your hair at a time.
Nonetheless, narrow plates also have the advantage of being more versatile. They can get as close to your scalp as possible and straighten the roots. Also, a narrow flat iron enables you to create unique effects such as flips and curls.
Another aspect to consider is the length of your hair. Narrow plates are better suited for short hair while wide plate sizes work well with longer hair.
Having the capacity to adjust temperature is preferred, but not an absolute necessary. Usually, flat irons with permanent temperature settings perform better with heat levels of at least 400 degrees Fahrenheit.
However, if you have fine or damaged hair, your best bet is to get one that has variable temperature settings. To guarantee safety, most straighteners are also equipped with automatic shutoff. For the best results, choose a flat iron whose shut-off period is about twenty minutes.
Flat Irons for Hair Types
Flat irons are designed with the different types of hair in mind. Although there are a few hair straightener models that work well with all hair types, some are compatible with just a specific type.
Flat Iron Materials and Technologies
As we mentioned earlier, most flat irons were, initially, made of metal. The problem with such metal plates is that they heated unevenly, forcing one to pass the flat iron through the hair numerous times. Also, the surface was rather abrasive, and this resulted in friction and damaged hair.
Thankfully, consumers now have a wide selection of materials and technologies that relate to flat irons. For instance, nano-platting technology is praised for making smooth plates as well as reducing the likelihood of uneven heating. When shopping for a flat iron, you should also account for the technology and material used in its construction.
Flat Iron Accessories
The primary purpose of adding accessories is to boost the safety, performance and versatility offered by a particular flat iron. For instance, some flat irons have fixed brushes. Others, however, are able to slide in and out.
Another handy accessory that may come with your hair tool is a flat iron holder. While some holders are designed to sit on a flat surface, others clamp onto a desk or table. You are also likely to find a heat resistant bag for easy storage of the flat iron, and gloves to protect your hands as you straighten or style your hair. For proper maintenance, some flat irons also come replacement plates and cleaning kits.
Failing to take proper care of your hair is a sure recipe for frizzy, tangled and unhealthy hair. Thanks to the present technology, you can keep your hair in good condition using quality hair tools such as a flat iron.
Some of the best flat irons on the market include the Corioliss C3 Black Straightening Iron, HSI Professional Ceramic Ionic Flat Iron, BIO IONIC Onepass, Conair Infiniti Pro and the RUSK Professional Ceramic and Tourmaline Str8 Iron.
When selecting a flat iron, be sure to take certain aspects into account. These include the type of hair, size and length of the plate and the technology used in making the flat iron.
