One of the most popular hair styling tools used by most of the peoples these days is a hair straightener. In the most common way this hair styling tool is used for the purpose of straightening your curly unmanageable hair with the help of heat technique. It changes the hair structure by applying heat to it. It was first invented by Erica Feldman in the year 1872. It was then nothing but hated rods used for the purpose of straightening or styling the hair. During the 1960s women tied to use this technique for straightening their hair by using clothing irons to remove unwanted curls and waves of their hair. It was only in 1909 that Isaac K. Shero got the patent of hair straighteners by using two flat irons that are heated and pressed together. Like most of the inventions the hair straighteners also underwent gradual change of development. And the hair straighteners that we use these days are undoubtedly credited to Lady Jennifer Bell Schofield. She was the one who, in 1912 combined made out the hair straighteners into a hinged, two plated heated iron. But that too is not the ultimate end of development of the hair straighteners. Far more developments are still in progress to make the hair straighteners better and far more safer and a thing of much more utility to be used more safely.

These days a large variety of hair straighteners are available in the market. These are quite easy to use and even you can use it at home without wasting a lot of money and time by visiting a hair stylist for the purpose of straightening your hair.

Now let us have a look how does a hair straightener work. The process that the hair straighteners use to straighten the hair is quite easy. The main thing is heat treatment. Breaking down the hydrogen bonds found in the hair’s cortex, which causes hair to bend and become curly is the main thing that is done by the hair straighteners to make the hair straight. Though it is true that the hydrogen bonds are reformed when exposed to hair but when it is broken the hair is unable to hold its original, natural form thus at that time you can easily give it the shape you want to mould it into.

With the development of technology the pattern of heating technique in the hair straighteners has also changed. The ceramic heating elements that are used these days for heating purpose are more effective because of their constant heating with a very fast heat-up time. Flat irons with a higher-quality plate is much more desirable as they straighten the hair much more easily and cause less damage to the hair. In good hair straighteners the ceramic coating is very hard and are sprayed in layers and baked on to perform the best. It is true that these units are much costly, while the less expensive units do not have any ceramic coating, rather sometimes have a paint-like coating, which is soon gone off causing a lot more damage to the hair cortex.

Generally hair straighteners are used only on dried hair. It takes a few minutes and then you can get your desired straight hair look. But the thing that should be kept in mind is that a hair straightener may damage your hair. Though a sensible use of hair straighteners doesn’t have much harmful effects on the hair but if you are desperate enough to use it daily, you are sure to ruin your hair.
