Best Flat Iron for Keratin Treated Hair – Top 5 Flat Irons [Comparison]

Keratin treatment gives you a perfectly straight hairstyle that is low maintenance and aesthetic to look at. You surely need a flat iron once you have left the hair salon after getting your keratin treatment done. The high heat of a flat iron seals the keratin in your hair and helps to keep it shiny and straight.

It’s really important 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.

This article will help you to find out which flat iron is going to work the best for your keratin treated hair along with the directions on how you can find your best choice.

List of Top 5 Flat Irons for Keratin Hair

Guide to Select the Best Flat Iron for Keratin Treated Hair

1. Make high heat a priority

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.

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.

They also last longer and most of them are set at a high temperature of 450° F. These plates reach extremely high heat in a very short span of time and can give you straighter results than ceramic plates.

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.

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

2. A long cord for 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. It doesn’t require you to stretch your hands in difficult directions, reducing hand fatigue and also providing free access to turn the flat iron in whichever position you want.

A flat iron with a long cord also reduces the time required to effectively straighten your keratin-treated hair in the best way possible. This in turn, also reduces heat damage leaving your hair smooth and comparatively healthy.

3. Floating Plates and Adjustable temperature settings for heat control

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.

Keratin treatment leaves your hair straight and shiny. While straight hair looks polished and professional, you can get bored of rocking the same look sometimes.

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. 

4. Temperature Display Screen and Auto Off Feature to cut off confusion

The main criteria for a flat iron for keratin treated hair are high heat, adjustable heat settings and a long cord. However, having an automatic turn-off and indicator light or display screen are also some important features to seek for in a flat iron for safety measures and better results.

A flat iron meant for keratin treated hair can get very hot. Leaving it on by mistake for hours can cause unwanted accidents. An automatic turn-off feature automatically turns the flat iron off after a set period of time canceling any chances of mishaps.

Also, an indicator light or temperature display screen confirms the actual heat setting of the flat iron so you will not burn your keratin-treated strands by mistake.
