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

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

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.
