Top 3 Low Temperature Hair Straighteners & Ideal Temp for Straightener

Nowadays, there are many devices for hairstyling and they come with varying features and temperature settings. While many persons opt for hair straighteners with the highest temperatures, high temperature doesn’t always equate to smooth and straight hair.

Instead, when you use the highest temperature inappropriately on your hair, it can lead to hair damage and burnt hair.

This is where low-temperature hair straighteners come in. With the right low-temperature hair straightener used in the right range and settings, you can achieve the hairstyle you desire and protect your hair from burns and damages.

This post will offer an exposition into temperature hair straighteners, what the temperatures on your flat irons mean, and the best low-temperature hair straighteners for you.

Temperatures on a Flat Iron

If you ever wanted to know the answers for any of below-mentioned questions, then, read through to understand the logic of “temperature on flat iron”:

  • What temperature is 1 on a flat iron?
  • What temperature is 5 on a flat iron?
  • What temperature is 10 on a flat iron?
  • What temperature is 15 on a flat iron?
  • What temperature is 20 on a flat iron?
  • What temperature is 25 on a flat iron?

Flat irons have varying temperature ranges, including low temperature and high temperature. 

For many brands of flat irons, the temperature control settings are numbered 1 to 25. These numbers often confuse many people because they don’t know what temperatures the numbers represent.

As a result, you find some persons randomly using any number and testing the amount of heat it produces.

Instead of groping in the dark and playing guesswork, you can use a simple calculation to tell what temperature the numbers on your flat iron represents.

The highest degree on many flat irons is 450, so with a simple division, you can make it work.

For instance, if your flat iron is numbered 1 to 25, then dividing 450 by 25 will give you 18 degrees at number 1. 

So, you can multiply all the numbers on your flat iron by 18 degrees to get the temperature. Therefore, number 2 translates to 36 degrees, 4 equals 72 degrees, and 10 would be 180 degrees 

15 would be 270 degrees, and 20 on your flat iron would be 360 degrees.

In summary, for a flat iron with and 450 degrees maximum temperature and 25 maximum control setting numbers:

  • Temperature is 1 is 18 degrees
  • Temperature is 5 is 90 degrees
  • Temperature is 10 is 180 degrees
  • Temperature is 15 is 270 degrees
  • Temperature is 20 is 360 degrees
  • Temperature is 25 is 450 degrees

While this calculation can help you gauge the temperatures better, it is in your best interest to purchase flat irons that come with precise temperature scales that you can read easily.

In case of confusion, reach out to the company or vendor you purchased the flat iron from and ask them to guide you on the temperature settings.

What is the ideal temperature for hair straighteners?

Many people ask this question often and again, especially as it concerns their hair type. People wonder whether or not they can use one hair straightener temperature for all hair types.

The big question is; is there an appropriate temperature for hair straighteners to achieve the best hair styling. The answer is both a Yes and a no. 

The best temperature for hair straighteners is the lowest temperature that allows you to straighten your hair without passing it through the iron multiple times.

Interestingly, this setting might vary depending on several factors, such as your hair type, the hair products you use, and whether or not your hair is damaged.

The minimum heat for curly hair varies from the minimum heat for fine hair, and this is the case for other hair types. However, here is a guide to help you maintain the best temperature for your hair straightener.

1. Fine, fragile hair

 For fine but fragile hair, you need to be careful when using straighteners to prevent damage to your hair. The best temperature for such hair should begin at 250°F and end at 300°F.

2. Normal hair 

For normal hair type, which is hair that is neither too coarse, fine, thick, nor wavy, temperatures ranging from 330°F to 350°F are most appropriate for your hair. This is because your hair responds well to hair straighteners without needing extreme heat. 

3. Coarse or textured hair 

This hair type requires you to work the temperature upwards from 370°F until you find a temperature that gives you the desired results. However, avoid going above 410°F.

4. Thick, stubborn hair

For stubborn and thick hair, you need extra heat, attention, and time to straighten it properly. Heat your straightener to 410°F and take it up to 450°F until you get what you desire.

5. Wavy hair

For naturally wavy hair, the temperature range of 350°F to 370°F is best for your hair to prevent damage and avoid frizz.

6. Synthetic hair

If you have any reason to straighten synthetic hair material or extensions, begin at the lowest temperature and not take it higher than 160°F because the hair is very fragile.

For hair types that fall between the ones we have listed above, you can adjust the temperature to get what you want. Even with the best temperature, use heat protectors to further protect your hair from heat damage.

What is the lowest temperature on a hair straightener?

Now that we have discovered that the best temperature for straightening your hair isn’t necessarily the highest heat, but the lowest heat that can get the work done. 

So, what is the lowest temperature for a hair straightener? 

The average hair straightener with the lowest temperature is at 200°F or lower. Many hair straighteners go below 160°F because of synthetic hair.

When should you use a hair straightener?

Whether you have straight, curly, coily, or wavy hair, hair straighteners give your hair a straight and sleek appearance and also make it easy to manage and style your hair.

However, is there such a thing as the right time to use a hair straightener and excessive use of hair straighteners? 

It is best not to use a hair straightener or any form of heat styling more than once or twice a week. However, some people with very stubborn hair straighten their hair every day. Although it is doable, you might end up burning and ruining your hair, or damaging your hair fiber.

Before straightening your hair, ensure that it is well shampooed, conditioned, and fully dry before using your hair straightener. If your hair isn’t clean, the hair straightener will heat the oil and dirt in your hair, further damaging it. 

Always monitor your hair and look out for split ends, dry or brittle hair, and curls, which are signs that you need to take it easy.
