Everyone asks me 'Which flat iron is the best?' and I always answer, 'What is your hair type?' before I answer with a specific flat iron. Unless you've tried it firsthand, chances are the iron you are thinking of buying might not be the best one for your hair. Let's narrow down the choices with a few key questions.

Which plate width?

Determine which plate width you need - one inch does not fit all. Selecting a plate width for your specific hair length will save you styling time and prevent damage. Not all irons come in all sizes so this can help you narrow down your selection.

Fixed or variable temperature settings?

Flat irons come in fixed or variable temperature settings. The type that works best for you depends on your hair's texture and your styling needs.

Is your hair thin, delicate, damaged or fine? Choose a flat iron with a variable temperature setting so you can control the heat and keep the iron from getting too hot.

Is your hair thick and hard to straighten? A fixed temperature would be a good choice for you so you can crank up the heat on those pesky pieces that just won't straighten.

Is your hair is somewhere in between? Most likely you will be fine with either choice. My personal preference is a variable setting - I like control.

Does it create curls?

Most flat irons today will create curls, but (ahem) the curls are only as good as the user who creates them, so brush up on those curling techniques.

Which Technology?

Ok, this is really the source of most flat iron confusion. Most flat irons on the market today have similar straightening technology, but which is best? Again, that depends on your hair type and styling needs.

Ceramic/Ionic

Almost all professional grade flat irons are Ceramic and Ionic these days. This technology is important in generating negative ions to smooth the hair cuticles. What you may not realize is NONE of the flat iron plates are 100% Ceramic. That's a myth. All plates are infused with Ceramic (and/or other materials) to straighten and smooth the hair. I kid you not!

Industry research shows that pure Ceramic plates would be too soft to get the job done, so all manufacturers (this means all of them!) use Ceramic along with a much stronger, heat conducting surface such as Aluminum, Titanium, etc. to straighten the hair's cuticles. And boy do they work.

Aluminum

Some older, lesser quality flat irons are pure Aluminum. These irons are usually referred to as the 'drugstore variety' and do not contain Ceramic. This is why you notice a huge difference when you upgrade to a pricier iron - the addition of Ceramic.

So you know what Ceramic does, but what about all of those other materials you keep hearing about? Tourmaline, Nano-Titanium, Nano Silver, Nano anything? These are additional materials used in the plates to enhance the smoothness of the plate's surface, generate additional negative ions to smooth your hair quickly, and create a snag free glide down the strands. Here's a breakdown:

Nano

This is a process where the material, say Tourmaline, is micronized into superfine particles and infused into the plate surface. Whenever you see Nano, think teeny, tiny pieces of a smoothing material infused into the plates. Nano-Ceramic, Nano-Silver, you get the idea.

Ceramic and Nano-Ceramic

Smaller particles of Ceramic to contribute to your smoothing process. This is good for every hair type. Most flat irons with Ceramic technology provide silky, straight results but there are a variety of price points. As for most irons I've tried, the pricier Ceramic irons really are better. Plus the more expensive irons usually come with additional features and benefits so be sure to look into this if you are considering a Ceramic iron.

Nano-Titanium

Super smoothing surface, great heat conduction, straightens hair up to 40% faster. Is it necessary? If your hair is hard to straighten, this is one of the best materials out there for you, newer technology but comparable to Tourmaline. If you want the latest technology you'll like this.

Nano-Silver

A smooth surface that eliminates bacteria on the appliance creating a germ-free environment every time you use it. Great for a stylist, or germ-a-phobe. It straightens hair well, but do you have to have it? Probably not.

Nano-Tourmaline

Tourmaline is a semi-precious gemstone known for its negative ion generating and smoothing properties, and is infused into the flat iron plates. This is earlier technology than Nano-Titanium and Nano-Silver. I sometimes find that Tourmaline causes static, but still a very good material for smoothing most hair types.

Does it come with a warranty?

The warranty is another biggie to think about. Some manufacturers will only honor a warranty if you buy the flat iron in a salon. I would consider that a fine idea if the salon in my area carried every flat iron. Truth is, they don't. But I have noticed the irons they do carry are way more expensive than online. What gives?

If you are buying a flat iron in a store or online, look for a flat iron that has a 1 year warranty or longer. We've all heard the rumors about a certain flat iron that breaks after only a few months. Honestly, it does. You might want to think about it. 'Nuff said.

If you use a flat iron every day you want it to last. Make sure you select a flat iron guaranteed to survive your daily styling habits. If you use a flat iron sporadically, go for a less expensive Ceramic iron without all the technological bells and whistles.

I hope you take the time to ask yourself these simple questions, the flat iron of your dreams is waiting for you!
