Best Flat Iron Reviews: Top 7 for 2018

Though to many it may feel like something of a regular phenomenon, hair straightening is actually something that has been around since the late 19th century. Back then, people didn’t have must choice when looking for the best flat iron, as the devices didn’t exist, instead of using a hot comb to get the desired effect. Of course, with the advent of electricity, new techniques came about, one of which was the flat iron that we are so familiar with today.

The History

Though straightening has been around for so long, the technique only really began to gain popularity in the 1950s, particularly amongst women and those men who wanted to achieve the ‘greaser’ look that was popular at the time.

Back then, people would use a hot comb or, in some cases, chemical relaxants in order to achieve the desired effect. The advent of the best flat irons made it all the easier to get your hair straightened, though some still prefer to go through the chemical relaxant route. The one that you choose is really going to be dependent on what you are looking for from your hair straightening experience.

Key Differences

The key difference in the techniques is that chemical relaxants create a more permanent effect in your hair, making it much more difficult to regain your old hairstyle. This means that many more people choose flat irons because they allow for a temporary solution while still providing the flexibility to go back.

Choosing The Best

There are a number of different factors that go into choosing the best flat iron, including the speed at which it operates, the heat it generates, and, of course, its effectiveness. Here we will take a look at 7 of the best flat irons that are currently on the market to see which one you should introduce into your own hair straightening regime.
