Flat Irons for Normal Hair Buyer’s Guide

With the right tool, straightening 4C hair is a simple and rather enjoyable process. However, you need to consider numerous features of straighteners to find out the most suitable for you. Once you find it, make sure the iron is durable and will serve you for several years.

How to choose the best flat iron for natural hair?

The trick in choosing the best iron for your hair lies in choosing the tool that fits you. It does not have to be the trendiest straightener as long as it keeps your locks healthy and shiny. Consider iron’s benefits and flaws before you buy it, and match it with your own hair type.

Hair type

woman-with-natural-hair

Pay attention to the thickness of your hair and its texture. Coarse and thick hair usually requires a higher temperature than thin. I recommend using flat irons with 450F maximum temperature. Thin hair is quicker to heat up and to style.

It does not need a temperature of more than 250F-300F, and you can switch to the lower modes. However, no matter what texture you have, the flat iron must come with adjustable temperature. You can change it anytime you want. Some irons offer you a digital screen on the handle so you can check out the temperature.

Different materials for diverse textures

Thin or fine hair prefers ceramic irons. Ceramic reduces frizz and holds the heat inside, which is beneficial for this type of hair. You may choose an iron with plates of ceramic, coating, or the tourmaline plates. The last one is the gemstone but has similar ceramic qualities.

Titanium plates would be beneficial for coarse hair of 4C and 4B categories. It is great for natural hair. These plates heat faster than ceramic and hold heat longer. Titanium is lighter than ceramic. It has an ionic charge, which helps to keep the moisture inside the hair.

Right size and width

You need to understand that there are multiple options for you on the market. You can easily find the best width and size of flat iron for you. Thin and small irons are great for people with short hair.

They are also beneficial for travelers who don’t have much space in their bags. Small irons are good for bangs. Large tools with wide plates are great for thick and long hair. They save your time, as you may style more hair at the same time.

Extra features

Pay attention to the features that flat irons offer you. They can be cordless, with dual voltage, with oils, negative ions, or nano protection. The cord can be long or short. You may require a digital screen with a temperature on it.

Check out whether the straightener has an automatic shut-off system after an hour or less of no use. It may save you from tragic accidents.

How to prevent breakage of natural hair using a flat iron?

Don’t trust people who say that flat irons are completely harmless for your hair. You work with the heating object, and you have to use protection no matter how great your iron is unless you can straighten it naturally. This is vital, especially if you use the straightener every day. Check out my recommendations for you:

  • You have to start with the lowest temperatures to find out which one is the best for you. Don’t go to the maximum at the very beginning, as your hair does not need it. Pay attention to whether the iron offers you to control temperature before you buy it;
  • Use oils before straightening the hair. Apply them on semi-wet locks. Argan and coconut are considered to be the most beneficial and effective. Spread the small amount of oil on your hair, and if it is not enough, repeat the procedure. Try to avoid rubbing the oil in the scalp, as you don’t want it on your skin;
  • Apply heat protectant. Chemicals inside these protectants close cuticles of your hair, so the iron does not dry it. Look for the protectants with silicone, as it is extremely effective against the heat;
  • Avoid dripping wet locks. Make sure that you don’t have the bubble hair once it is heated. It causes almost irreparable damage to your hair, especially if it is thin or already damaged by other tools. If you heat the water on your hair it turns into steam and gets inside the hair as bubbles. The hair becomes more breakable. Before you start, soak your hair into the towel for several minutes;
  • Straightener of great quality. Make sure it contains all the features you want; it is durable and matches your type of hair. Check out other buyers’ reviews. I gathered only the most reliable straighteners on the list. You may start with it.

Negative ions will be beneficial, as they prevent your hair from frizz. As for the width of the plates and the length of the iron, you can decide by yourself, depending on whether you want curls or straight, glossy hair. For curls, use thinner plates; for straight hair, use thicker ones.

Is ceramic or titanium flat iron better for natural hair?

Both types of irons have their benefits. For example, if you need a tool that can make your hair straight and curly, depending on the mood, use ceramic. If you have kinky and hard to straighten hair, use titanium plates. You may buy both and switch them depending on what hairdo you prefer today. It is a smart investment that will keep your hair healthy.

Do I need to dry my hair before using a flat iron?

No, you don’t have to dry your hair completely. All you need is to make sure that the water is not dripping from it to avoid the bubble hair effect. Use a towel for this. Soak your hair carefully with it.
