An ionic iron is a type of straightening hair tool that produces negative charges to help to neutralize moisture within your locks during use. True ionic irons generally feature ceramic plates, and some versions even contain other parts, such as tourmaline, to enhance the production of negative charges. When choosing an ionic version of the flat iron, you should look for a quality product that is appropriate for your hair type. Heated irons come in a variety of widths, so it is also important to purchase the right size that will adequately straighten your locks.
Flat irons traditionally make your hair dry, especially when you use them often. Although heat-protecting products, such as sprays, can help, the repeated use of a flat iron is bound to damage your hair over time. When your hair is dry and damaged, it has a positive charge, causing static and split ends. An ionic iron produces negative charges to seal hair follicles shut and to lock in moisture. These types of flat irons are purportedly safer for hair, especially if it is already dry and damaged.
Ionic irons come with a wide range of features that help to prevent damaging the hair. A true ionic-based iron will feature ceramic plates, and not metal ones. Some versions contain tourmaline, titanium, and nano-technology, all of which are promoted as ways to speed up the process of ironing so that you do not have to repeatedly style the same section of hair. Nano-ionic irons are also helpful if you are using the tools on multiple clients in a salon, because they inhibit the growth of germs on the plates.
Aside from finding the desired features for which you are looking in a flat iron, it is also important that you choose the correct width that matches the thickness of your hair. Choosing too small of a width will likely lengthen the time that you spend straightening with an ionic iron. Flat irons most commonly have plates that are one inch (25.4 mm) in width, but they are also available in different sizes in between one to two inches (50.8 mm). Generally, the thicker the hair, the wider the plates you will want to find in a flat iron.
The downside to an ionic iron is that any type of heated tool is bound to dry out your hair in the long-run. If you desire straight locks, there are steps that you can take to protect your hair from damage while still using a flat iron as your go-to styling tool. Consider styling your hair every other day, and touching up with a dry shampoo on alternate days to remove excess oil. Always use heat-protecting sprays on each section of hair before using the iron in order to minimize damage. You might also consider a weekly deep moisture replenishment treatment to prevent dryness and frizz.
