Unfortunately, straighteners only work for one or two days because the hydrogen bonds usually reform. Nevertheless, straighteners help people with curly get that professionally straight look at home.

Types Of Flat Irons

Flat irons are classified into four kinds, which give you the classy straight look, you always wished.

Ionic Flat Irons

Firstly, an ion is an atom or molecule. The term ion is concerned with hair straighteners in a sense where it generates negative ions, which help make your hair straight and last longer. Your hair is generally a positive charge because of the water present in them. When the positive ions of your hair blend with the negative ions of the straightener, it neutralizes the process and gives you a straight and smooth finish.

Ceramic Flat Irons

Ceramic is one of the essential parts of a flat iron. These ceramic plates allow you to have an even distribution of heat. Where there is an even distribution of heat, if it isn’t present in your flat iron, it ends up having unevenness in temperature. Another ability of ceramic plates is that it reduces the risk of burning your hair, which is an essential factor while choosing the right flat iron.

Tourmaline Flat Irons

The Tourmaline flat irons are known for its continuity in generating heat. Tourmaline is a chemical that is ground to powder and used for coating metal plates, generally in ceramic. They have a more prodigious output of negative ions compared to titanium and ceramic, which gives a sleek straight look.

Titanium Flat Irons

Titanium is said to be a good conductor of heat, which allows you to have a simultaneous flow of heat even at low temperatures. Using flat irons at low temperatures improves damaged hair and the risk of burning. The titanium also can heat up quickly and has a high ionic factor.

While straightening people often feel it is very time consuming but with the help of titanium plates, it transfers heat quickly and makes the whole process easy and fast. The only benefit that is better in terms of ceramic plates is its quick heat up. People prefer to use titanium for its additional benefits, which are less compared to ceramic plates.
