Ceramic plate flat irons work exceptionally well for people who have thick hair and are very popular for women in the natural hair community with thick type 4b and 4b hair, women with thin hair may like to use a ceramic iron as long as it is thinner in diameter.

While ceramic plates are gentle on your hair, they may not give you high-end results like titanium plates. Also, a lot of products and chemicals are used on your hair during a keratin treatment.

Titanium Flat Iron For Keratin Treatment

Titanium irons are known for heating up quickly and staying hot consistently during use. The best flat iron for relaxed hair with titanium plates is exceptional at maintaining consistent heat levels. They deliver a powerful ionic charge that helps impart smoothness and shine to your damaged tresses.

As titanium plates are inert, they are not going to interact with any of the products giving you hassle-free and smooth shine.

Tourmaline Flat Iron For Keratin Treatment

The latest technology in hair straightening and curling is tourmaline. The term tourmaline refers to a gemstone or crystal that is crushed into a fine powder. The fine powder is used to coat the ceramic plates.

Flat Iron For Keratin Treatment Buying Guide

What Is A Flat Iron For Keratin Treatment?

The flat iron for keratin treatment offers unique features that make it suitable to make the most out of your keratin-treated hair. Some of these features are keratin-infused plates which allow you to heal and straighten your hair in one go.

This protective protein is less prone to tearing or scratching than the other cell types produced by your body. And it makes up both your hair and skin. As a result, when the hair cuticle absorbs this vital cell element, it strengthens your hair, the root of your hair, and the scalp altogether to give you stronger and healthier hair.

So when you take a Keratin treatment or a Brazilian blowout straightening, it revitalizes your hair and your scalp.

How Does A Flat Iron For Keratin Treatment Work?

Flat irons in general, work by breaking down the positive hydrogen bonds found in the hair’s cortex, which cause hair to open, bend and become curly.

Flat iron for keratin treatment not only tames your dry, dull, brittle hair but also resuscitates it long term. And buying the best flat iron for keratin treatment is key to getting the most out of this treatment.

Features To Look For In A Flat Iron For Keratin Treatment

Ionic Technology

Ionic technology in flat irons is pretty much the norm. The negative ions are responsible for smoothing your hair strands, reducing frizz. You can make the best out of this technology using a Keratin hair straightener. The ions, rich in protein, work faster on your hair than traditional ionic hair straighteners since your scalp absorbs the protein for quick healing.

High Heat

A flat iron with high heat capabilities is a necessity not only during a keratin treatment but also after the completion of the keratin treatment. Activating the keratin requires high heat. For this, you need a flat iron that can easily reach 425°- 450° F temperature without heat fluctuations.

Plate Material

The best flat iron for keratin treatment can be made with different materials. They can come with tourmaline, ceramic, titanium, or a combination of these materials. These materials are different when it comes to cost, heat-up time, durability, and heat distribution.

Titanium is more expensive but more durable. Tourmaline heats up quickly while ceramic helps with even heat distribution. A combination of these materials will give you a much better tool to achieve better results.

The best choice for providing your keratin-treated hair with high heat is to choose a flat iron with titanium plates. Titanium plates are hotter than ceramic plates.

Plate Protectors

Keratin flat irons or any other protein-infused flat iron comes with delicate plates that get easily damaged if not stored securely. The shock-sensitive plates break easily. Besides, dust whits mar the infused micro-conditioners undermining their effectiveness if you leave the plates in the open air for too long.

Therefore, it’s important for your flat iron to have plate protectors so the plates remain secured when not in use. It’s a trait every top flat iron possesses. They either come with hinge locks or protective sleeves, or both.

Adjustable Heat Settings

A flat iron with 425° – 450° F heat is essential to activate the keratin during and after 72 hours of the treatment. But a range of heat not more than 400° F is enough if you wish to use a flat iron after a month or two of the keratin treatment.

For this reason, choosing a flat iron with adjustable temperature settings is very essential for keratin treated hair. A flat iron with a number of high-temperature adjustable settings is best for keratin-treated hair.

Not only it gives you total heat control, but also provides you with an opportunity to create different hairstyles with the same tool.

Floating Plates

A flat iron with adjustable heat settings and floating plates not only straightens your keratin-treated hair, but also provides you with the opportunity to create different hairstyles like temporary waves and curls.

Dual Voltage Capacity

The best flat iron for keratin treatment has dual voltage. You can use them anywhere in the world safely and conveniently. The best flat iron for relaxed hair that is dual voltage caters to 110-120v and 220-240v, allowing for use with any power system in the world.

A cordless hair straightener would also be great for an overnight or weekend getaway. Just charge it up before you go and you won’t have to worry about voltage at all.

​Automatic Shutoff

Distraction is one of the reasons why you might forget to switch off the steam hair straightener after use. To avoid risking the safety of your premise, get a straightener that includes an automatic shutoff feature.

This feature gives you peace of mind knowing that the flat iron will automatically power off if left unattended for some time.

Digital Controls & Display Screen

Keep an eye for a design that has digital controls with an intuitive LCD. Digital controls allow for easy temperature adjustments. You just have to tap on the positive or negative sign. The LCD readout displays the exact heat level you have selected.

An indicator light or display screen are also some important features to seek in a flat iron for safety measures and better results.

Easy Access

The process of flat ironing keratin-treated hair is extensive and time-consuming. Such a prolonged process can cause hand fatigue which can result in uneven straightening results.

The case worsens if you are using the flat iron to straighten your keratin-treated hair on your own. In this case, flat iron with a long cord can really come in handy. A long cord ensures ease of usage and convenience.

Common Questions About Flat Iron For Keratin Treatment

Why do you need a flat iron for keratin treatment?

It’s absolutely key to straighten your hair twice a day with a suitable flat iron for the next 72 hours of getting your keratin treatment done. As keratin stays in your hair for the next 72 hours and high heat activates it, a worthy flat iron can do wonders to seal the keratin in your hair fibers and make the treatment last longer.

What is the difference between a flat iron for keratin treatment and a regular flat iron?

  • Keratin Infusion. This dissimilarity undoubtedly tops the list. Traditional flat irons don’t come with Keratin infused plates.
  • Plate material. Choosing the plate material becomes a vital part when you buy a traditional flat iron.
    Namely, titanium for thick hair, ceramic for thin hair, that’s how you usually make the selection.
  • Moisture detection. This is one of the core features of Keratin flat irons. It helps balance the moisture levels and protein infusion while also ensuring the consistency of moisturization.
    In contrast, traditional hair straighteners care little about the moisture levels of your hair.

What are the benefits of keratin treatments?

  • Smooth, shiny hair. Keratin smooths cells that overlap to form hair strands, which means more manageable hair and less frizz. This makes for hair that dries with little frizz and has a glossy, healthy look to it.
    Keratin can also reduce the look of split ends by temporarily bonding the hair back together.
  • Long-lasting results. As long as you care for a keratin treatment by not washing your hair too frequently (2 to 3 times a week is enough), then your keratin treatment can last up to 6 months.
  • More manageable hair. Keratin treatments make hair more manageable, especially if your hair is particularly frizzy or thick. If you constantly heat style your hair, you’ll notice that with a keratin treatment your hair dries more quickly. Some people estimate that keratin cuts their drying time by more than half.
    Your hair may also become healthier and stronger since you can air dry it more often, saving it from heat damage.
  • Hair growth. Keratin can strengthen and fortify hair so it doesn’t easily break off. This can make hair seem to grow faster because the ends aren’t breaking off.

Can you use a flat iron on keratin-treated hair?

Blow dryers and flat irons are the best tools to use to keep your tresses smooth and straight after getting a keratin hair treatment. Because the weight of the keratin will hold your hair right, you don’t need to use hair styling products like hair sprays or gels, mousse, root-lifting sprays, etc.

Which straightener is best for keratin-treated hair?

BaBylissPRO Keratin Straightening Iron can be used for performing Brazilian Keratin treatments as well as for styling keratin-treated hair. This lightweight flat iron straightens coarse hair and leaves it silky smooth, even if you don’t have a keratin treatment in your hair.

How hot should my flat iron be for keratin?

The flat iron should reach 450 °F for the keratin treatment to be activated. In the course of the treatment, a flat iron is important to maintain the temperature set without heat fluctuation. The same flat iron can be used after applying the keratin treatment.

Does heat ruin keratin treatment?

Hot water can melt away freshly applied keratin, and you need to avoid it as much as you can.

What to know to maintain your keratin treatment longer?

  • The type of water on your hair matters. Swimming in chlorinated or salt water (basically a pool or an ocean) can shorten the life of your keratin treatment.
  • You’ll also need to invest in shampoo and conditioner that are free of sodium chloride and sulfates, as these can both strip the treatments.
  • Wait to wash. You’ll have to wait for 3 to 4 days post-keratin treatment to get your hair wet, so if you’re not a person who likes skipping wash day, then this treatment may not be right for you, and some people report a musty smell even after washing.
