Keratin Flat Irons Buying Guide

What Is a Keratin Hair Straightener?

The functionality goes precisely with the name. These flattening irons are equipped with Keratin infused plates. Keratin is the building block protein key for the anatomy of your hair, nails, and skin. This delicate element, once damaged, can affect the new cells beneath your hair by no longer protecting them. It causes hair damage, rough and dry hair, or brittle hair.

Having been infused with Keratin protein, a Keratin hair straightener preserves the natural protein of your hair and locks the moisture. It eliminates frizz and gives your hair a revived look while protecting it from extreme heat settings. With specific properties, the micro Keratin conditioners strengthen your hair for the longer term.

Keratin flat irons hardly lack the functionalities of traditional flat irons. They can be heated as much as your regular flat iron so you can straighten your hair the way you are used to. Besides, their design is pretty much similar as well. The best thing regarding these flat irons is, they suit every hair type. They provide excellent nourishment and revamp your hair texture.

Types of Keratin Flat Irons

There are two types of Keratin flat irons to choose from according to the necessity of your hair. They are as follows.

1. Keratin Flat Irons With Keratin Infused Plates

This is mainly the type by which we define a Keratin flat iron. It’s the type we have already discussed in our previous segment. The plates can be infused with argan oil or different proteins along with Keratin.

Titanium or Ceramic plates are infused with micro conditioners that help resuscitate your hair. They are also great in making your hair look glossy and shiny. These flat irons are excellent alternatives to Keratin treatment.

To further clarify, you’ll need a protective flat iron once you have taken a thorough Keratin treatment or a Brazilian blowdry. In general, your hair retains the effect of such treatments for up to five months. During this period, if you feel like straightening, you’ll have to use a Keratin protect flat iron.

It’s important you always use a protective flat iron for your Keratin treated hair since the regular ones may totally ruin the polished look of your hair. A protective flat iron detects and maintains the extent of heat necessary for your treated hair and protects it from overheating. It also preserves the nutrients beneath the hair strands and prevents damage.

Profashion Steam Infrared Heat Ceramic Flat Iron and CROC New Classic Flat Iron are among our favorite protective flat irons for Keratin treatment protection. You can also go for Karma Beauty Professional Titanium Hair Straightener if you are short in budget.

Key Differences Between Keratin Flat Irons & Traditional Flat Irons

There are several dissimilarities between Keratin hair straighteners and the traditional straighteners. We have figured them out for you down below.

Keratin Infusion

You must have understood this difference by now. This dissimilarity undoubtedly tops the list. Traditional flat irons don’t come with Keratin infused plates.

Importance of Plate-material

Flat Iron Heating Plate

Choosing the plate material becomes a vital part when you buy a traditional flat iron. Titanium for thick hair, ceramic for thin, that’s how you usually make the selection.

For Keratin flat irons, on the other hand, this is hardly an issue. The infused plates hardly affect your hair as long as they’re able to detect the temperature necessary for your hair, no matter the material is titanium or ceramic. However, titanium plates heat up faster with better heat level retention.

Moisture Detection and Lock Functionality

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 a little about the moisture levels of your hair.

The Advantages

  • Provides the necessary protein required for your hair.
  • Suits every hair type.
  • The quickest solution to get rid of frizzy, dry, or damaged hair.
  • Nourishes and heals your hair for the longer term.
  • Protects the cells underneath your hair strands.
  • If the micro Keratin conditioners reach the root of your hair regularly, it’ll maintain the proper growth of your hair.
  • Detects and locks the necessary moisture of your hair.
  • Gives your hair a glossier and shinier look and a lasting result.
  • A cheaper alternative to Keratin treatment or Brazilian straightening.

The Disadvantages

  • You’ll have to buy another one once you’ve used up all the infused Keratin. This can happen well before a year round.
  • Takes high maintenance. The plates, along with the effectiveness of protein wane away fast if not securely stored.

The Core Features of a Keratin Infused Hair Straightener

There are some core features you’ll find in Keratin hair straighteners distinguishing their capabilities from others. Down below we have listed the special functionalities. Let’s discuss them in detail.

Keratin Infused Plates

Keratin Infused Plate

Undoubtedly, this is the trait the flat iron is named after. As we have mentioned above, the plates of these flat irons are infused with Keratin protein which allows you to heal and straighten your hair at 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 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. The result lasts long enough as well. No wonder why the trend is becoming more popular day by day.

Since the cost of such treatments is too much to afford, Keratin hair straighteners can be the cheaper alternative you’ll be interested in. They provide your hair with the same protective protein similar to those treatments. They smooth down your overlapping hair cells with each use, and your damaged, dry, frizzy hair heals fast.

In contrast, your hair gets damaged and brittle when it lacks this protein. Besides, this lacking causes rough, cracked scalp.

Optimal Use of Ionic Technology

Ionic technology in flat irons is pretty much the norm. The negative ions are responsible for smoothing your hair strands, reducing the 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.

Working only on strands, ionic hair straighteners without protein infusion cannot smooth down your hard to tame hair strands as fast as Keratin hair straighteners. So you’ll be glad to have this feature in your straightener for quicker results.

Smart Moisture Adjustment

Moisturized Hair

Keratin flat irons boast moisture detection and locking functionality. It’s an important feature for proper nutrition of your hair and precise hair straightening.

When you apply heat on your hair through a regular straightener which lacks such functionality, it heats up your hair regardless of the existing moisture of your hair.

So, if your hair happens to be moistened already, the possibility of burning your hair will be there if you do not adjust the temperature properly. Moreover, even if it doesn’t burn your hair, the natural moisture can be lost, which could result in hard to recover rough and dull hair.

Keratin hair straighteners, on the other hand, with the moisture detection and locking technology along with the temperature auto-lock feature, detect the moisture of your hair.

It then makes sure your hair gets the precise amount of heat and protein infusion required for your hair. As a result, neither remains any risk of burns nor the risk of overly dampened look. Besides, straightening becomes a lot easier.

Temperature Adjustment and Auto-lock

This is a must-have feature for a good protein infusion flat iron. With this feature, a Keratin infused flat iron ensures your hair gets the proper heating without the risk of burns.

This ancillary feature to the smart moisture adjustment system detects and locks the necessary heat to seal the required moisture.

If your protein infused iron lack this feature, it’s possible that your hair gets affected by improper moisture adjustment. So a temperature setting higher than necessary can burn your hair, and a lower setting can disrupt the moisture levels. Both are harmful to your hair.

Quick Heating

Quick Heat Up - V1 Aug

These hair straighteners heat up quicker than every other hair straightener type. It’s an essential feature to have for quick styling for sure. But for a protein-infused flat iron, the feature is even more important for a longer lifespan.

If your Keratin iron takes longer to heat up, suppose a minute, the infused protein ions start evaporating during this period. Despite being a slow process, it makes the protein wane faster in the long run.

A good iron won’t take more than 20 seconds to heat up, saving your time and extending its life.

Plate Protectors

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

So 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. The sleeves come real handy as a quick storage solution of hot plates when you’re in a hurry.

These protectors secure the plates from unwanted scratches, breakage, and preserve the effectiveness of the infused protein micro-conditioners. Besides, they spare you the headache while traveling.

Few Additional Features: Among other notable features, you’ll find-

  • Ceramic, ceramic tourmaline, titanium, and titanium tourmaline plates with a smooth surface.
  • You can adjust the temperature within the range 300-450 Fahrenheit.
  • Floating plates for even heat distribution in every hair section.
  • Rounded plate edges for easy maneuvering and proper reach of every hair section. They are also helpful for additional styling options including curls, flips, and waves.

The Reason We Do Not Recommend the Following

Keratin Complex Stealth V Digital Smoothing Iron

This popular Keratin flat iron comes with titanium ceramic plates. The unusual yet ergonomically designed flat iron offers a comfortable hold with easy movement.

The product claims to provide extra smooth hair within moments which we reasonably doubt. Here’s why.

It lacks a smart moisture adjustment system, a key feature for Keratin infused hair straighteners. As a result, it fails to determine the required moisture for your hair. So the protein emission happens without proper balance.

Moreover, the absence of a temperature auto-lock functionality worsens things up since it leaves your hair vulnerable to burns unless you’re well wary about your hair’s moisture levels and temperature settings.

Additionally, the lack of floating plates, inappropriate temperature setting for delicate hair, and a longer heating time indicate to the incompetency of this high-priced flat iron.

MHU Professional Keratin Ion Flat Iron

The ceramic tourmaline ionic flat iron from MHU is a simplistic Keratin flat iron suited for all hair types. The long tongs of this unit provide additional comfort while styling.

The iron offers multiple heat settings within a convenient range of 280-450°F. It allows you to straighten every hair type with different thickness level. However, the lack of smart temperature adjustment system takes it a few steps back since you’ll have to be wary about burn protection.

It disappointingly lacks a moisture adjustment feature as well which leaves you with risking your hair with improper moisture levels. So you may not get the luster you’re craving for. Besides, it may not even heal your damaged hair properly.

The iron also lacks floating plates and plate locks adding up to its ineffectiveness. After all, you get what you pay for.

A Few Tips From Our Experts

As we’ve mentioned before, styling your hair with a Keratin flat iron is “almost” similar to taking a Keratin treatment at home. But again it’s not literally the solution itself.

So our experts tip you some secrets that’ll help you get along with Keratin protein and retain the effects all the time.

  1. Avoid washing your hair frequently.
  2. Use shampoo free of sodium laureth sulfate or sodium lauryl sulfate.
  3. Never forget to blow dry your hair after each shower. Avoid hair supplements after the initial shampoo.
  4. Avoid greasing your hair through excessive touching.
  5. Lessen the use of hair clips. Avoid ponytails and braids.
  6. Sleep on a silk pillowcase instead of cotton.

Final Say

The latest trend of Brazilian blowout is surely a tempting one, and so is the idea of having it done by a professional. While this temptation can cost you heavy, a Keratin flat iron could be a big money saver for the longer term.

By now, you must have a comprehensive idea about Keratin hair straighteners. Now you know how they work, why you need one, and what will suit you best. So, make your selection wisely, get majestic hair at home.
