How Hot Should a Flat Iron Get?

Using the proper temperature flat iron is important for maintaining your hair's health while straightening.

Use Adequate Heat for Desired Results

The flat iron must reach a temperature between 360 and 410 degrees Fahrenheit to achieve the desired results. For thick, coarse and very curly hair, the temperature will need to be between 380 and 410 degrees Fahrenheit. The flat iron must also maintain a consistent temperature.

Too Much Heat is Damaging

A flat iron should be set at a lower temperature if used on thin, fine or naturally straight hair to prevent breakage, dry ends and overall damage to hair. The flat iron should be set at less than 360 degrees Fahrenheit for thin or fine hair.

Bottom Line

Purchase a flat iron with multiple temperature settings and remember that higher temperatures will cause more damage, especially when used daily, so use the lowest temperature that is still effective for your hair type.
