 Which is better – steam straightener vs flat iron? What are the pros and cons of each? And which straightener is better for curly hair. Find out more here!

If there is one hair styling tool that is a favorite of many women out there it’s the hair straightener. But did you know that there are several different types of straighteners?

The most popular one of course is the flat iron which straightens hair by clamping down your strands between two hot plates to change their texture.

But there are others like hot brushes, steam hair straighteners and even blow dryers that help straighten hair. 

And choosing one among these can become a real dilemma. 

So today I will expand on the differences between a stream straightener and a flat iron and which one you should choose!

Steam Straightener Vs Flat Iron

Steam hair straighteners simply refer to hair styling tools that have a barrel full of hot water that turns to steam while you use it on hair. This makes straightening easier as it provides extra heat and moisture. Steam straighteners can be either hot styling brushes or flat irons. It’s just that these tools use steam as the primary source of heat. 

Flat irons can come in different materials too like ceramic, tourmaline, or titanium. But the chief difference between a steam straightener and flat iron is that water is used in the former but a flat iron simply uses hot plates to straightener hair. 

What Is A Steam Straightener

A steam hair straightener can resemble a flat iron at first glance. But the main difference between the structure of both hot styling tools is that a steam straightener has a chamber where you need to fill in water and its plates have tiny ceramic bristles (that resemble a boar bristle brush).

Now the water chamber obviously needs to be filled up with fresh water every time you use the straightener on your hair. 

And the bristles help move the steam to the hair, so it’s not the plates that are straightening your hair. 

Steam straighteners are really effective on natural 4c hair!

Pros And Cons Of Steam Straightener

Advantages of Using a Steam Straightener 

  • A steam straightener is one of the best hairstyling tools for low porosity hair as it helps open hair cuticles and adds moisture to the shaft.
  • It also helps frizzy hair look shiny and smooth as dryness is one of the main causes of frizz. 
  • If you’re worried about direct heat causing damage to your hair, then a steam straightener is good for you. They don’t cause “hot spots” in hair as they don’t use plates. 
  • Steam straighteners are a much better option for curly/coily/4c hair types as they give high temperatures but don’t supply direct heat. And also because the steam helps control frizz.

Disadvantages of Using a Steam Straightener 

  • The bristles on the steam straighteners make it difficult to straighten large sections of hair at one go. So using a steam straightener on very thick or long hair can get difficult.
  • You have to fill in the water chamber every time you use the steam iron. So that can get quite frustrating
  • As steam is the only source of heat in these types of straighteners, the tool won’t work if the water in the chamber dries out completely. So you can expect the steam straightener to work only for 15-20 minutes tops.
  • Steam is gentler on hair than direct heat from plates. However, the steam can stay on hair and increase the temperature. So it can actually cause damage to fine, thin hair.
  • You cannot control the temperature of a steam hair straightener. 

What Is A Flat Iron

Flat irons are what we call “regular hair straighteners”. They usually consist of two plates made of either ceramic, tourmaline or titanium that can straighten hair by passing it between them.

These plates are smooth to prevent snagging or tugging of hair and certainly don’t come with bristles like the steam iron does. 

Pros And Cons Of A Flat Iron

Advantages of Using a Flat Iron

  • Flat irons do not require water to be filled every time before use. So it’s less cumbersome to use a flat iron, especially if you’re straightening hair on a busy morning.
  • Also, the lack of bristles and the variation in the width of flat iron plates means that you can straighten wider sections of hair and longer hair in one go. 
  • Flat irons are much better for high porosity hair as these hair types will not take kindly to excess moisture from the steam.
  • Ceramic flat irons get heated up slowly and distribute heat evenly so are much better for finer, damaged hair. 
  • The biggest advantage of a flat iron over a steam straightener is that you can control the temperature on this device and go low or high depending on your hair needs. 
  • Flat irons also come in different sizes and are generally lighter due to the lack of a water chamber. So these are much more convenient for travel.

Disadvantages of Using a Flat Iron

  • Some flat irons can create “hot pockets” where one area of the plate is more heated than the rest. This can lead to damage and uneven straightening. 
  • Unless the flat iron is equipped with negative ion technology it’s not very useful for controlling frizz. 
  • You might need to go over curly hair several times to get it right with a flat iron.
  • There are several different materials of flat irons and you’ll have to match one with your hair needs exactly to prevent damage and increase efficiency of straightening. For example, ceramic does better with thin, damaged hair while titanium is better for thick hair.

FAQs About Steam Hair Straightener Vs Flat Iron

Are steam straighteners good for curly hair?

Yes, absolutely. Curly hair needs a lot more heat than regular hair textures to get perfectly straightened. Yet at the same time, they are more fragile and prone to damage. So these are perfect for straightening curly hair as the steam doesn’t directly heat the curls yet the moisture removes frizz to give you perfect straight locks. 

Do steam straighteners make hair frizzy?

No, not at all. On the contrary steam straighteners are your best bet if you’re going to straighten frizzy hair! Dry hair is one of the biggest reasons for frizz. So a steam straightener that helps open up cuticles and adds moisture to your strands can help control frizz to a certain degree. 

Do flat irons ruin your hair?

The correct answer here is… it depends. Any sort of heat applied to hair whether from the different types of flat iron or any other heat source will damage hair to a certain degree. However, the amount of heat and the fragility of your hair is what determines if a flat iron will ruin your hair. 
A ceramic flat iron which doesn’t get too hot and heats up evenly will not cause much damage. But a titanium flat iron might be safe on thick, curly hair but end up ruining fine, thin hair as it gets too hot. 

Final Thoughts on Steam Straightener Vs Flat Iron

To sum it all up, steam straighteners are the better match for coarse, frizzy hair as they provide extra heat and the moisture from the steam can control frizz to a certain degree.

However, if you have straighter, finer hair textures than I’d suggest going for a flat iron, especially one with a ceramic coating as they help distribute heat evenly and don’t get too hot. 

Additionally you should also consider hair porosity while using these products. 

A steam straightener can do low porosity hair much better as it opens up hair cuticles and provides a sort of conditioning treatment by allowing moisture to penetrate the hair shaft. 

On the other hand, high porosity hair which is already prone to hygral fatigue might not appreciate all that steam.

So choose wisely!
