This buyers’ guide is also going to help you make good decisions when buying a flat iron, plus give you the confidence to analyze any hair straightener you come across – from size and features to materials and your hairstyle.

Materials – Ceramic, Tourmaline, and Titanium Straighteners

Ceramic Hair Straighteners

20 years ago, Ceramic plated hair straighteners were officially introduced into the hair styling market. Since then, they’ve become one of the most demanded hair straighteners because of not just their ability in heating up quickly, but also their even distribution of heat, as well as how well they hold the heat.

Ceramic is also known to straighten hair even when the temperature is low. Because of the ionic technology in ceramic made straighteners, they are able to increase the health of your hair, making your hair smooth, and eliminating any kind of frizz effects on your hair.

A little Caution about Ceramic straighteners: most of the flat irons on the market are not made of ceramic. They are just coated with ceramic. When you lay your hands on a Ceramic-coated flat iron, it might work for you initially, but as time goes on, when the coating wears off, then problems will begin to develop. You should, therefore, be careful when buying a ceramic-coated flat iron.

Tourmaline Hair Straighteners

Though some hair styling professionals mistakenly combine both ceramic and tourmaline flat irons, the two are different and should be seen as so. Tourmaline-made flat irons are great for increasing the heat on the hair, whiles making sure that smooth finishes, pulling of hair, and tugging are prevented. It also helps prevent the drying of your hair by repetitive means.

When it comes to the production of wavy and negative ions, tourmaline is known to lead the way. These negative ions are excellent in drying hair, removing frizz, and making your hair look nice.

If you are searching for a well styled, frizz-free, and shiny hair, you might like to try a tourmaline flat iron as you will get maximum satisfaction.

Titanium Hair Straighteners

Among the three categories – Titanium, Ceramic, and Tourmaline hair straighteners, Titanium is known as the best hair straightener when it comes to immediate results: it has the fastest heating time, no matter the type of hair you carry. Though Titanium is of the heavy iron type, which might not be ideal for all types of hair, it works well for all those with curly, thick hair.

Titanium is also widely known as the best heat conductor. As a result, the type of weather doesn’t matter, titanium made flat iron will keep your hair in good shape.

Flat Iron Size – Standard, Small, and Large

The size of a hair straightener will most likely depend on the type of hair you carry. Let’s go through that.

Standard Sized Hair Straightener

These are hair straighteners that have plate sizes of 1 inch. An example of such is the BaBylissPro Plate in Ceramic. Standard Sized Flat irons are known to work for many hair types. The sizes of these straighteners are fairly good at styling almost any kind of hair.

It is admitted that they are not fit for all hair types, it is mostly however used for all purposes.

Small Sized Hair Straightener

Small sized flat irons, mostly have sizes below 1 inch. They are considered ideal for short hair and the kind of hair that demands that you be near the scalp. This type of hair straightener is good for both fine and thick hair that are short.

Fine, short hair demands that the amount of heat you use when styling is controlled, and this is best handled with small sized plates. Small plates also ensure that the slow movement that is required when styling and straightening thick hair is well done.

Small plates come in sizes such as 0.5 and 0.7 inches and are used, generally, for precision. An example of such straightener is the CHI model.

If you are after precision, if your hair is short and fine, and you want an excellent styling experience, check out the BaBylissPRO Nano Titanium-Plated Ultra-Thin Straightening Iron.

Large Sized Hair Straighteners

If you are the type with long hair, then you will want to straighten your hair without any difficulty. This means that you will need flat irons that come with longer and wider plates, this will make straightening your hair more comfortable and quicker. Naturally, large sized straighteners are also known for styling thick or coarse hair because they are good at easily gripping and penetrating hair.

Large sized flat irons also ensure that your styling time is reduced, and prevents you from going over the same hair spots several times just to style your hair. Any flat iron with a plate more than 1 inch is considered large sized.

Plates with inches of 1.25, 1.5, and 1.75, including 2 inches, as well as 2.5 inches all fall under the large-sized flat iron category and, are ideal for long, thick hair. Do you have long, thick hair? Are you looking for the number one flat iron for thick hair? Then look no further. Go for the Croc Classic, Nano-Titanium Flat Iron. This is large and wide enough to go through your thick, long hair.

The bottom line on Size
The size of flat iron you buy depends on the type of hair you have. It’s not just about your hair size, or whether yours is thick or fine. What you should also consider is the texture of your hair. If you have a thick, long hair, then you can go for a longer and wider straightener. If your hair is thick and fine, you will still be better off with a longer one. If, however, your hair is short, fine, and thick is good to go for a short straightener.

Ultimately, you should always look at the texture, the size, and the type of hair you have before you decide to either buy a longer, shorter or wider hair straightener.

Temperature Considerations

Many hairstyles: amateurs and professionals, believe that higher temperatures are always better. But that’s not completely true. The whole thing depends on the type of hair you have. There are certain hair types that when exposed to higher temperature, might become damaged in a few days.

The temperature that comes with many of the hair straighteners on the market ranges from 175 degrees to 450 degrees Fahrenheit. The type of hair you carry: thick, coarse, long, and fine, determines the temperature level to use in straightening your hair.

For those with thin hair, it is always advisable to go for low temperatures when styling. This will help ensure that your hair doesn’t fry up totally. For those with coarse, thick, and stubborn hair, as well as those with curled and tight hair, the ideal type of flat iron is one with higher temperature.

One precaution to take, however, is that a temperature of more than 450 degrees Fahrenheit is not good for your hair. No matter the type of hair you carry, such high temperature might not be required. And you should be very careful not to go beyond such temperature level as that might cause considerable damage to your hair.

Weight and Grip

One thing many people don’t pay attention to when buying a flat iron is the weight. Heavy straighteners are sometimes difficult to use for a long time. Also, a light straightener can also breed problems, especially they can easily break. So when you enter the market, look at the weight of the flat iron before you buy.

Have you ever considered the grip of a straightener before buying? Probably not. It’s something you think is unimportant when buying a straightener. However, just as the kind of material, the size, and temperature, the grip of a straightener is very important. If the grip is uncomfortable for you, when the time comes for you to get pretty, you might find it difficult styling.

If your hands are small, then you should go for a straightener that comes with smaller grips. That means you should buy a smaller plate sized flat iron. If you have bigger hands, then you can consider buying a larger sized straightener.

Final Words

Everything discussed the best hair straightener for thick hair, including the type of materials, the size of the straightener, the temperature, and the additional features that include automatic shut off stands, and mats are authentic reviews. They are verified, and you should carefully go through them so that whenever you are buying a hair straightener, you will know that you are going in for the best and nothing else.

Now it’s time for you to make to make a decision as to which one to go for. Thick hair is not something you would want to live with for a very long time. Doing so will put your entire beauty you’ve worked for at risk. That’s why it’s advisable to shop right now and choose the one that suits you – the material type, your hair texture, the size of the straightener, the weight and grip, and a whole lot of other features.

Straightening your thick hair doesn’t have to be a hurdle. You should do it right away.
