What is a keratin flat iron?


Keratin is the protein that makes up our hair, nails, and skin. With age, this element diminishes leaving the hair brittle, dull, and rough. This is why you need to switch from your regular flat iron to a keratin flat iron.

Though keratin flat irons, look similar to regular ones they are built with keratin-infused plates that straighten the hair. They preserve the natural protein of the hair and eliminate frizz. Bringing your locks back to life once again!

These tools give high heat output that seals hair cuticles ensuring shiny and silky tresses that last for a longer period. And the best part is that they suit every hair type!

What is a Brazilian keratin treatment?

Brazilian keratin treatment (aka Brazilian Blowout) is a chemical procedure done to get shinier, silky, and straight hair. It cuts down frizz and moisturizes the hair so that you can manage your hair with ease.

Though the cost of getting the hair keratin-treated is a bit too high, it’s worth it, as the look lasts for over 6 months. Besides, for the best results, it’s suggested to get the Brazilian treatment done from a trustworthy salon.

Can I use a flat iron after keratin treatment?

This is the most common question amongst all those who get their hair treated with Keratin.

And, the simple answer to this is “Yes”.

In fact, for the first three days, it is recommended to straighten your hair twice a day with a flat iron to ensure that the keratin gets absorbed in the hair faster.

However, you should be careful with the kind of flat iron you are using. It’s generally recommended to use titanium or ceramic plated flat irons that can achieve a temperature of 450F. Plus, it’s quite obvious that you can’t use the iron at a high temperature always. So, make sure you get one that allows variable temperature adjustments.

Furthermore, keratin gets reactivated with heat, thus you can always use a flat iron to retrieve your glossy look at home.

Why are Titanium plates important?

The material of the flat iron plates also plays an important role. Normally, keratin flat irons with titanium plates tend to give amazing results.

Titanium metal is capable of reaching high temperatures within a few seconds and distributes the heat evenly. Additionally, as you start straightening your hair strands the plates will retain the heat levels consistently. As a result, you get beautiful, shiny, and straight hair in a few minutes.

Not only this but, Titanium plated flat irons deliver excellent results faster when used to straighten thick hair.

How to Pick the Best Flat Iron for Keratin Treated Hair: Buying Guide


Once you know that there are flat irons available in the market for keratin-treated hair, the next question is “How to choose your ideal one?”

There are several points to consider before purchasing a flat iron for keratin-treated hair. Let’s check the essential features that every hair straightener should have.

1. Titanium Plates:

Titanium-plated hair straighteners are highly recommended for keratin-treated hair. The titanium plates heat up faster and retain heat for a longer period, making it extremely easy to style even the super thick hair.

Titanium plates not only reach high temperatures but also do not fluctuate heat. The heat is also evenly distributed as compared to ceramic irons. This way keratin gets activated and gives the hair a perfectly smooth finish.

2. Adjusting Temperature

High heat is necessary to activate and seal the keratin in the hair cuticles. After getting your hair treated with keratin it is good to expose them to high temperatures regularly. This helps activate the keratin and maintaining the sleek look.

You should always pick a keratin flat iron that features adjustable heat settings. It should be capable of heating up to at least 450F. This will deliver the best results.

3. Other Features

A good Keratin flat iron needs to have smart moisture adjustment and adjustable heat settings. The plates should have a rounded clamp that makes it easy to handle the hot tool. Also, it should have floating plates to ensure no gap between the plate, resulting in even heat distribution.

In addition to this, the size of the flat iron also matters. If you have fine or thin hair, a narrow-sized flat iron can get the job done. Alternatively, if you’ve got long or thick hair, it’s better to opt for a wide plate flat iron.
