What to Look for in a Good Hair Straightener


Most flat irons that you will come across are made from ceramic, tourmaline, and titanium. There are some that combine one or all of these materials and then some during manufacturing to make the plates deliver the best results. But to make the best decision, you need to know the value of each material for your hair. Each one has its own key feature that makes them appropriate for certain types of hair. Here’s what you need to know:


Aside from being resistant to corrosion, it has a lower thermal conductivity compared to metal. Look for one that has the plates covered with several layers of ceramic as this will help prevent your hair strands from getting snagged, burnt, and even broken when you heat them up with the plates. This is one of the best materials to use on different hair types because it generates heat evenly so as not to burn your strands. There are no hotspots to worry about where your mane gets more heat compared to the other. That said, if you are looking for a versatile flat iron, then this one comes highly recommended.


A titanium flat iron also works for most hair types and can easily heat up the plates too. As a matter of fact, it will only take up around 30 seconds for the plates to reach the highest temperature which reduces your waiting time considerably. Although this works well for those who are in a rush in the morning, this may be a bit tricky for those with fragile hair since if you will compare the same temperature on a titanium straightener and one made from ceramic, you will get more heat from the former. Although it is said that titanium can be used on all hair types, you still need to exercise caution when you have fine or dry mane as the high heat can damage your strands. If you have thick long hair, this is a good option for you. The same goes true when you have curly hair. You can opt for gold plated flat irons or one that is made from titanium to help iron your curly locks.


Flat irons with plates made from tourmaline are somewhat the same as ceramic with its density as well as having a fine surface. The difference lies in the plates generating more negative ions that are actually useful for those who have damaged or unnatural strands. Getting a straightening tool that is made from tourmaline and ceramic helps your hair considerably because it uses the best of these two materials in one.

Plate Size

You should also factor in the size of the plates when you want to use a flat iron for your mane. The smallest one in the market is 1/2″ which works perfectly for those who have short hair. The 1″ plate size is suitable for all hair types as it has the right width to clamp down on each section of your mane. Since this is considered to be the average size, it has become a versatile option for different kinds of hair. The 1″ plates are best suited for those who have normal to a bit wavy hair that is of medium length. This makes it easier for you to straighten or even create loose waves with it in a precise manner.

Then there are the 1.5″ plates which are recommended for those who have thick long hair or if you want to speed up the styling process. Since the plates are wider, it will be able to close down on more hair strands so you don’t have to spend a lot of time ironing your mane. Another plus to choosing this size is that the width gives a good grip on your hair thus cutting back the time it takes to achieve your desired results.

Depending on hair length and thickness of the hair it can take 15 – 20 minutes to straighten.

1. Set the temperature of the iron

2. Start an inch from the root and pull the iron downwards to the ends, holding the hair taut. Be careful to not burn yourself!

3. Repeat the process, continuing the straighten in small sections

4. When working with the back part of the hair, take the piece of hair close to the scalp and pull the iron up vertically to ensure no kinks near the root.

To create volume at the back of the hair cross a small section of hair over the opposite side of the head to straighten
