Temperature settings for flat iron range from 140 degrees Fahrenheit to 450F and each level is suitable for different hair types. We are also going to specify each level to match the hair types.

However, you must bear in mind that some flat iron has fixed temperature while some have an adjustable temperature. The fixed temperature irons are likely to have 356 degrees as their heat level and therefore cannot go higher than that. It is only on adjustable temperature flat irons that you will see temperature levels as high as 450 degrees Fahrenheit.

So, your choice to go for either a fixed temperature flat iron or an adjustable iron will be determined by your hair type.


If your hair is thick, you can start with the heat level of 356 degrees. When you try this heat out and it failed to straighten your hair, you can go higher to 410 degrees with an adjustable temperature flat iron.

One good thing though, this hair types are not easily damaged by heat but are hard to be straightened with low heat.


The normal hair types do not require much heat to get straightened or styled. Some of the available brands with fixed temperature settings can work wonders on the hair.
