Some tips to straighten thick hair

Having thick hair might be one of your best features but they do come with a lot of baggage. In order to maintain the beauty of such magnificent hair, you need to make sure that you’re taking care of it as well. Although it can take some time to manage and care for it, the results are always worth the effort.

Straightening can be done easily without giving much thought to it but if you have thick hair then it can be a whole other task for you. The straightening process for thick hair comes with some tips and instructions to get the ultimate results.

Using protective spray:

Always have an at-hand protective spray with you whenever you’re styling your hair with a hair styling tool. Thickness is a thing of beauty at all times but can often go dry. This makes it sensitive to heat which is usually emitted by hairstyling tools. In order to prevent this, use a protective spray on your hair so that it can shield you from heat damages and help you grow a healthy amount of hair.

Way of gliding:

The most effective technique of straightening your hair is dividing it into equal sections so that it’s easy to glide through each part of your hair without missing any strands. This way the heat will evenly distribute to each part of your hair making it more shiny and glossy.

Another way is to move the flat iron from the roots to the ends. You should start as close to the roots as you can, this can completely enhance the straightening effect. Moreover, each time you pass the flat iron through your thick strands it will easily glide along with the straightener.

Use of combs and brushes:

Using comb-over dry can cause a lot of frizz which might make it difficult to manage your hair. The shows that using a brush will be ideal with dry hair as it won’t create any static which can cause hindrance during the whole styling process. Static is the one factor you need to keep in mind before straightening otherwise the whole effort of straightening will go to waste.

Mistakes that lead to no results:

Do not straighten your hair while it’s wet. It is quite common that when you’re in rush you try doing things without thinking much of the consequences. Similarly, whenever you’re in a hurry you might straighten your wet hair without dry it completely, this can boil your strands making it highly prone to heat damage.

Another mistake you do can be not cleaning your flat iron; this will lead to poor performance. If there are any excess hairs or buildup from the hairstyling then make sure that you wipe it clean. Some might not give much thought to it but can have a lot of effect on the whole process.

Wrong size:

Buying a flat iron that doesn’t match the size of your hair can be quite a problem. If you have long hair then using a flat iron quarter its size would be tedious to work with. In order to avoid this, you need to choose a straightener that agrees with the size of your hair and doesn’t cause problems later on.

Buying Guide for the Best Hair Straightener for Thick Hair

The first thing one needs to do before choosing any hair styling tool is to figure out the type of hair you have. Then only you can determine the styling needs your hair has to have. Here, if you have thick .i.e. you feel how wide it is on your fingertips then you will move on to the next part:

The optimum temperature for thick hair:

Although the amount of temperature needed on your hair depends on its texture. Is it coarse and unruly? Or Sensitive and light?. The untamable and coarse it is, the more heat you need to apply to it.

However, if your hair is sensitive to breakage then you need to use as low a temperature as you can. The ideal temperature for thick hair ranges from 350-450 degrees Fahrenheit.

Plate material:

There are two very common plate materials present in flat iron.

Ceramic: This type of plate material can be found anywhere and provide a very even distribution of heat to all parts of your hair. Ceramic plates are affordable as well.


This is another type of material that is extremely durable and has a long-lasting effect on your hair. The material is used for q quick heating up of plates that reach high temperatures effectively.

Plate size:

This is another feature you need to consider, flat irons come in all plate sizes but the most common size is 1 inch. If you have hair that is thick but not as thick then 1 inch is an ideal choice for you.

Considering the length of your hair is an important part of choosing a flat iron. If you have long hair then you need to choose a flat iron that has wide plates that can easily and efficiently accommodate your hair size without wasting much of your time.

Cord size:

You might overlook this feature as it doesn’t have anything to do with the functioning of a flat iron. However, the size of a cord is an important part of maneuvering and moving without any frustration. The size of the cord needs to be long enough that it reaches the plug and does not restrain your movements.

If you keep getting tangled with the cord without getting anything done then you might feel frustrated. Therefore, choosing a cord long enough for unrestraint movement is ideal.

For a comfortable and convenient experience, consider these factors:

Grip: You should be able to grip the flat iron comfortably without much hassle. In order to achieve this comfort, you need to choose a flat iron with a strong grip. There should be a non-slip grip feature for such functionalities.

Weight: This is another part you need to be careful about since here, we’re talking about thick hair. We already know it demands a lot of time and attention. Having a light straightener will make the whole process extremely comfortable for you. You can easily maneuver it around and use it to its full potential without ending up with aching muscles.

Control buttons: It is important to check where the control buttons are placed on the flat iron. If they are placed somewhere in your way while you’re straightening then they can ruin your whole process.

As you might press something like the temperature or power buttons that can mess up the whole system. Make sure that you choose a straightener where the control buttons are placed clearly somewhere your hands can’t reach.
