You can choose the best cordless flat iron by taking into consideration the plate material, temperature range, and size of the plates. The plate material is especially important for people who frequently flat iron their hair, since the heat is distributed more evenly, causing less damage. Getting a cordless flat iron that heats well enough to fully straighten your hair is important too, so knowing how much heat your hair needs is key to picking the best iron. The size of the plates is also important, as it will determine the amount of time you take styling with the iron, in addition to the ease of styling.
Ceramic plates are an important feature of any flat iron, cordless or corded. This kind of material conducts heat evenly, helping you prevent burning or having different degrees of straightness throughout your hair. Most professional hair stylists make certain their flat irons are plated with ceramic rather than gold or some other material that conducts heat poorly. Some flat irons have plates made of pure ceramic; flat iron plates that are simply coated with ceramic may quickly become worn, showing the metal underneath, which comes into contact with your hair.
Once you have narrowed the selection down to the best coated flat irons, look at their temperature ranges. To keep your hair the healthiest, always use the lowest effective temperature to flat iron your hair. A cordless flat iron with a very high temperature capability might be tempting but also unnecessary. If you do not know what temperature works best on you, ask your stylist or borrow a friend’s styling tools to find out for yourself. Buying a cordless flat iron can be a big purchase if it is high quality, so getting it right the first time takes some effort.
Another aspect to consider is the size of the cordless flat iron. Most people can straighten their hair with regular-sized flat irons, which range from 1 to 1.5 inches (2.5 to 4 cm) wide. If you have thick or long hair, however, you might benefit from a cordless flat iron with wider plates for more coverage. Likewise, people who have short hair might be happy with a mini cordless flat iron. Getting the most convenient size is not necessary, but size may affect the flat iron’s battery life, temperature range and how easily it is to handle with one hand.
