Professional Flat Iron Buyer’s Guide
When shopping for an easy-to-manage and reliable hair straightener, one may feel completely overwhelmed with the number of options available. There are dozens if not hundreds of flat irons that differ in size, shape, plate material, number and variety of heat settings, etc.
This buyer’s guide is designed to help you find out what it is that your hair needs. I will share my smarts on the subject and teach you to choose the one professional grade flat iron that meets your every need and turns your hairstyling routine into an exciting experience. Read on to make sure you invest your money, time, and efforts into the right product.
How is a salon-grade flat iron different from the ordinary one?
Compared to more costly hair salon flat irons, consumer-level products often do not provide enough staying power to keep your styled hair straight throughout the day. If a hair straightener fails to produce enough consistent heat, your hair will quickly get back to being frizzy, especially on a damper day.
Professional products usually require you to apply minimum heat on your hair to get a perfect and consistent result, whereas, in cheaper flat irons, the heat level will often fluctuate, causing irreparable damage to your locks.
What to look for in a professional flat iron?
It is essential to know what to look for when picking a new flat iron if you want this appliance to last you for years and protect your beautiful locks from unwanted damage. Here are some of the most crucial aspects you will need to consider when you shop for a hair straightener.
Despite what the name suggests, not all professional straightening irons are flat. Their versatility depends on their shape. Thus, mildly rounded plates can turn a traditional hair straightener into a curling iron if needed, and sharp edges will give your hair a very straight look.
Plate size and width
The right size and width of plates depend on the length and thickness of your hair locks. Wider plates will get the job done faster, but if your hair is fine and short, you should probably opt for a flat iron with plates of just 1-1.5 inches. Narrower plates are also handier when trying to reach hard-to-access places.
Considering your hair texture, you can choose one of the three most commonly used materials – titanium, ceramic, and tourmaline.
- Ceramic plates work most nicely on fine hair, both light and coarse. They distribute heat evenly and can keep a reliably hot temperature for as long as you need. However, flat irons with ceramic coating tend to wear down with time.
- Titanium plates will easily manage even the most unruly hair. Quickly heating to higher temperatures, these flat irons can make short work of very coarse and thick hair.
- Tourmaline is a material that belongs to the boron silicate mineral group. Ground down to fine powder and infused into ceramic plates of a flat iron, tourmaline produces more negative ions and helps protect damaged hair by trapping the moisture within the hair.
Temperature control options
Higher heat means faster results, but not all types of hair will benefit from too hot irons. If you want to minimize the damage to your hair, choose an appliance that comes with adjustable temperature settings, and then use the lowest heat option that produces the intended effect.
Price vs value
There is no denying that miracles do happen, and you may be lucky enough to purchase a $20 appliance with premium-grade functionality. Most of the time, however, you will find the quality of a cheaper product to be in direct correlation with its cost, and at some point, you may regret not opting for a higher-priced pick.

Professional Flat Iron FAQ
Below, I’d like to provide you with the most common questions people have when buying a flat iron.
Do I need professional flat iron?
While they are a costlier option, professional straightening irons can give you salon-grade results without the need to use chemicals or expensive products for styling your hair. Besides, these appliances are usually made to treat your hair with more care and delicacy, so damage from long-term use will be minimal.
How will I know if the temperature setting is correct?
Professional flat iron reviews say that the secret to gorgeous-looking straightened hair is choosing the right heat setting. Do opt for straighteners with adjustable heat controls rather than fixed ones.
Stick to the lowest possible temperature setting that allows you to get the desired result in one quick pass. Many stylists claim the most optimal temperature for a flat iron to be around 365° F.
How often can I use a flat iron?
Even the best pro flat iron can harm your hair if used incorrectly or too often. Experts agree that there ideally has to be a 24-hour gap between the two sessions. If styling your hair every other day is not an option, you can minimize the damage by choosing the right type of straightener and using a suitable heat protectant.
