Are All Flat Irons The Same?

There are different kinds of flat irons, as they are designed with various materials. These include:

Ionic Flat Irons  

Ionic technology uses nanomaterials to trap moisture in the hair, making them look silkier and shinier. Flat irons constructed with this material are ideal not only for fine hair, but for frizzy hair, curly hair, wavy hair, dry hair, or coarse hair.

Ceramic Flat Irons  

Flat irons designed with ceramic plates ensure even and balanced heat distribution. However, after some time, the coating starts to peel off, causing damage to your hair. These flat irons are suitable for moderately curly or wavy hair, but if your hair is frizzy, this kind won’t leave your hair as sleek and smooth as some of the other kinds.

Wet to Dry Flat Irons  

These flat irons are constructed with a venting system that enables them to work on damp or wet hair. They work best on wavy hair as it allows them to straighten their hair in a single step.

Tourmaline Flat Irons  

The plates of such irons feature ground tourmaline dust on them. They require a lower amount of heat to straighten the hair and produce negative ions, which is why they are ideal for all hair types.

Titanium Flat Irons  

Although these irons are similar to tourmaline, they have some additional features. They quickly heat up and produce negative ions. These irons are a bit expensive, but they work well with all types of hair. 

What Makes a Flat Iron Great for Fine Hair?

Flat irons can transform fine hair and make them look healthy and shiny, but choosing a wrong flat iron can wreak havoc on your hair. If you want a flat iron for fine hair, it is vital that you keep the following considerations in mind:

Plate size

The best flat iron for fine hair is one with one-inch or 1.5-inch plates, as fine hair has less volume. Such irons are also lightweight, which, in turn, makes them travel-friendly. Make sure you select a model that can help straighten all types of hair, including baby hair, side bangs, curls, etc.  


Pay special attention to the design because you do not want a model that is heavy and causes fatigue to your hands while ironing. Go for a lightweight, sturdy, and ergonomic design to make flat ironing your hair a breeze. Moreover, a 360-degree swivel cord, as well as, a comfortable grip on the handle can make it easy to maneuver the iron while using.

Material and Heat Settings

Most of the models available come with multiple heat settings. These are helpful as they enable you to choose a temperature according to your hair type. Very high heat is not recommended, as it can damage your hair and give it a plastic look. Make sure you use moderate temperatures for natural-looking locks. Also, if you want to reduce static charge and frizz, it is better to invest in tourmaline and ceramic-coated plates.

Why it Stands Out to Us

There are many things about this product that we like. Using volumizing gels, sprays, creams, and mousses add body and volume to your hair.

Who Will Use This Most

Perks of Getting a New Flat Iron

Unmanageable hair can be a constant source of irritation in women. Using a flat iron not only gives you great hair but also provides the following benefits:

Ease of Use

The best thing about flat irons is that you do not require the assistance of another person. You can use it to style your hair whenever you please.


Owning a flat iron saves not only time and money, but energy also. You can style your hair anywhere, which saves the time you might have to spend in a salon. They are lightweight and can be stored easily, thus making them a perfect accessory while traveling.  

Protects Your Hair

Permanent straightening is a process that requires the use of chemicals, which can be quite damaging not only to the strands but also to the roots. On the other hand, straightening your hair with a flat iron is much safer, as no chemicals are involved. Moreover, flat irons are safe to use on dyed hair also.  

How to Use Flat Iron if You Have Fine Hair

The following are the steps that ensure efficient use of the flat iron:

  1. Divide the hair into sections with the help of bobby pins or clips.
  2. Don’t take large sections, as it can cause a crease underneath when you use the flat iron on it.
  3. Take one to two inches of hair and section them diagonally back.  
  4. Use a fine-toothed comb on the hair and follow it with a flat iron. Clamp the plates and slowly glide through the hair.
  5. Make sure that your movement is slow but fluid. Do not hold the iron in one position for too long as it could damage your hair.
  6. For fine hair, you require less compression. Therefore, you should remove your other hand from the plate.
  7. Also, make sure your movement is slow as you just need to go through your hair once or twice and not more in order to achieve great results.
