What to Look For in a best bio ionic flat iron?

Cord Length

In the bathroom or near the mirror, you may not need a long cord if you are planning on styling hair, but if you don’t have an outlet nearby, you may want to choose one with a long cord (“professional” length). When it comes to cord length, our participants had an average of 8.1 feet (or “professional” lengths). If the cord swivels, that is a great feature so you can move around more easily.

Auto Shut-off

Turning off an iron when running late is something we all do, so having an auto shut-off feature is “a little bit of peace of mind.” The tool shut off in our testing from five minutes to two hours, which is excellent when you are not sure if you turned it off — but we still recommend powering it down and unplugging it after use to make sure it is completely shut off.

Heat Settings

Flat irons with multiple heat settings allow for more versatility and versatility when dressing because you may select a temperature that works for your hair type/demands. Every hair type needs a temperature range, howerver, you should not crank the heat up all the way to 450 °F, though, as higher temperatures may destroy hair's protein content, resulting in irreversible damage. We recommend starting at a lower temperature and increasing as needed, as temperatures above 450 °F might damage hair's protein content, resulting in irreparable damage.


The fundamental decision to make when purchasing a hair straightener is to pick out the best material for your hair type—specifically, which one will get your hair straight and cause the least amount of damage. Ceramic, tourmaline, and titanium are all good choices for flat irons,The type of hair you have will determine which one is best for you.” Because ceramic irons do not heat as intensively as metal irons, they are the most common and most delicate. They are best suited to delicate or fine hair, and colour-treated or chemically-tortured hair that is prone to damage.


If you want to save time styling your hair, look for nice-to-have features such as swivel cords and long cords. It will be easier to use around your head with extra-long cords and swivel cords.

Plate Width And Length

For styling, 1-inch plates are ideal, It makes the tool simpler to handle and work in hair, or it makes getting closer to the root of the hair easier. These plates also make curling, bending, and waving easier, and they're more efficient at close proximity to the hair root. When hair is very long, however, a 1.5- or 2-inch plate size can make things simpler.
