Things To Consider While Buying Flat Iron for Thick Hair

The below mentioned factors will guide you to get the best suitable product for yourself.

1. Plate width

Depending on your hair thickness and length consider the plate size. For example, if your hair is till shoulder or shorter than that- 1 and 1 ½ inch is suitable.

For longer than shoulder then 1 ½ – 2 inches is suitable.

2. Composition of plate

After deciding the size of your plate, you can look for its composition. The most popular type is ceramic and titanium. Ceramic plates heat up evenly and give you a smoother finish. But if you are looking for durability than titanium is a better option.

3. Variable heat settings

Some straighteners provide low, medium and high heat. It is better to invest in a straightner that provides an adjustable temperature setting, this makes it convenient to choose a desirable heat setting.

For thick hair you can choose a temperature between 300F-450F.

4. Dual voltage capacity

If you are a frequent overseas traveller. Then check if your iron has dual voltage capacity. 110V and 220V are the two options of dual voltage. This will let you use it at home and also abroad.

5. Safety timer

If you are a forgetful one and always wondering if you have plugged or unplugged your flat iron. Then here is an ideal feature for you.

Some flat irons come with 60-minute auto shut off and pre-programmed heat settings. This gives you peace of mind and it doesn’t even cost higher than the iron that does not have this feature.

6. Warranty

It is always better if your product comes with a warranty. This just makes the product more reliable as compared to others.

7. Wet to dry straighteners

Wet to dry straighteners are a great option for people who are pressed with time. These flat irons promise to work on wet hairs. So after you take a shower you can directly use this on wet hair and eliminate the process of blow drying. With every pass your hair gets dried and straight.

Well the manufactures are still working on this technology to make the product better and to add value to the grooming process. Though some consumers have reviewed that their flat iron works better on damp hair but that doesn’t imply that these straighteners are preferably suitable for wet hair.

People with thin hair might be more beneficial with the technology but for people with thick hair might have to work a few extra steps to get better results. And we would be looking at this in the next section.

With the advancement in technology, very soon we shall see a variety wet to dry straighteners. But till then we would suggest to dry hair completely and then straighten other your hair might become frizzy.

Steps to straighten thick hair

1. Wash and condition hair

It is always advisable to wash the hair before straightening. If your hair is dry use a hydrating shampoo and clean your hair. Or choose another shampoo depending on the hair type.

Also apply a conditioner once you are done washing with shampoo. Leave the conditioner for 5-7 minutes and then wash off.

2. Towel dry hair

After you have washed the hair. Use a towel to dry it. This step will reduce the task of a blow dryer. For towel drying use a microfiber, this fabric is more absorbent and softer than cotton.

3. Use a heat protector

Since thick hair requires high temperature it is better to use a heat protector. Apply this before you start straightening. This will coat the hair and prevent it from burning out or drying.

4. Blow dry using a round brush

Thick hair requires a bit more effort for straightening. While blow drying the hair use a round bristle brush to pull it straight. This step will also reduce the effort required by a flat iron. And make sure the hair is completely dry before you start straightening.

5. Section and comb

After this prepping is done section your hair and comb it well. Sectioning will make sure no hair strand is left behind and combing it well will prevent the flat iron to pass over any tangles.

6. Swiftly move the flat iron

Start heating the hair from at least 2 inches away from the roots. Glide the iron fast instead of holding in one spot for long.

7. Apply serum

After you are done with straightening apply a serum to add a shine to your hair. This will make the hair look glossy and smooth.

Tips to straighten thick hair

Now that you have chosen a flat iron to treat your thick hair let’s look into some tips that can help to get a glossy, smooth frizz free hair.

  • Make sure your hair is dry before you use a flat iron. Otherwise your hair might sizzle on contact with the hot flat irons. And this can intesly damage your hair. So make sure to get your hair dried. You can towel dry it, blow dry it or even air dry it.
  • Oil your hair before you start grooming. Most hair nourishing oils available in the market provide some protection to hair. So use this before you start straightening.
  • Choose the right temperature for your hair. Though for thick hair more heat is required but it is suggested to initiate from the low temperature.
  • Most people with thick hair face this problem of less volume towards the root. This is because after straightening the weight of hair is pulled downwards. To overcome this try using dry shampoo on the root or try using some volumizing treatment.
  • Section your hair properly and also comb thoroughly. This will ensure no hair strand is left behind and prevent the flat iron from passing over any hair tangle.
  • After straightening, always use a serum. This will lock in the style and prevent frizzy hair for hours.

Things to avoid while straightening

  • Not cleaning the plates of straightner properly

Before you start straightening check if the plates are clean. Any deposit left on the plate can damage your hair and also the efficiency of flat iron. Make sure to do the cleaning while the device is unplugged

  • Nor drying hair well

In a rush you might miss drying your hair. But try and avoid this as it damages your hair for the long term. The hot plates of straightners can make the et hair frizzy.

  • Not choosing the correct size

This is the most important thing. If you select a small flat iron for long hair then the grooming will take much longer than expected. And if you get a large flat iron for small hair then this might make the task difficult.

So choose the size of device depending on your hair.

  • Keeping the flat iron in one spot for too long

This is one common mistake the most people do. For thick hair you need to use high temperature. And applying the high temperature on one spot of hair can cause damage.

While dealing with high temperatures you need to be quick. Instead of holding it one place quickly pass the plates over hair.
