InfinityPRo by Conair Rainbow Titanium Flat Iron

This flat iron is made of ceramic material which adds to the features and is important to remember for curly hair.

Floating plates also help you curl your hair and do other hairstyles other than straightening.

My favorite part about this flat iron for curly hair is that it delivers 450-degree heat and shines technology. But despite this high heat, the ceramic and titanium technology helps to protect hair strands from hair damage.

HSI Professional Glider Ceramic Tourmaline Ionic Flat Iron Hair Straightener

I personally like this straightener as it works wonders on coarse hair and keeps it from further damage.

The glider ceramic flat Iron includes an HSI style guide that gives you a 1-year warranty. 

This hair straightener has moisture lock technology to help protect hair. It is however very important to always apply heat protect serum right before you style.

The plate is made of tourmaline material and is 1 inch wide which helps in the smooth straightening process.

I found it less damaging than one might expect as the eight micro-sensors with heat distribution technology don’t let your hair get overheated. 

Pros

  1. Comes with a one year warranty
  2. The flat iron is 1inch wide
  3. Emits ions rich in moisture
  4. Eight microsensor technology

  2. No lock features
  3. Takes time to heat

Ghd Classic Original IV Hair Straightener

The flat iron for curly hair offers one optimal temperature that claims to effortlessly straighten, curl, or wave every hair type. 

It also promises to smoothen and eliminate frizz for a long-lasting result. 

But I found that the high constant temperature isn’t much of a bother. Why? Well, it is equipped with ceramic heat technology for everyday styling.

The ceramic ensures there’s no hot pockets forming and that your curls are protected.  

You can place the hair straightener at the tip of the hair and glide slowly it straighteners curly hair strands with ease. 

Pros

  1. Temperature control setting
  2. Heat protect coating
  3. The ceramic material of iron
  4. Moisture lock technology

  6. Adds shine and moisture

Cons

  1. Takes time to heat up

One key factor is that this flat iron is cordless so you can carry it around wherever you go, allowing hassle-free travel.

Types of flat iron 

There are three types of flat iron materials available in the market - titanium, tourmaline and ceramic. Let's look closely at which ones suit more for curly hair.

Titanium irons

Titanium irons are beneficial for extremely coarse or thick hair because of their heat transfer system. It evenly distributes heat to each section of the hair follicle. These irons produce the negative iron effect which adds moisture and keeps hair protected.

Tourmaline irons

This material is known for its moisture-locking abilities. This iron material gets heated in very little time so you can rest assured your hair is protected from damage.

Tourmaline material needs to be fused with other materials, it is used as a coat in ceramic irons. These materials help in hair damage control. 

Ceramic flat iron 

This flat iron is commonly used in the styling industry and is known for its even distribution features. It provides smooth and hassle free straightening while locking in moisture. 

In most hair straighteners, the hair gets damaged as the irons used are often not heat protected. 

It can easily strip hair moisture so to ensure you don't end up having dry strands it is important to use the right material for your hair type.
