Step1: Heating up the flat iron


  • If you have thin hair, you should use the lowest setting.
  • You can use a medium heat (approximately 300–350oF/150–177oC) if your hair is normal thickness.
  • Temperatures between 400 and 450 degrees Fahrenheit are ideal for thick hair. This is a good place to start and then work your way up until you are able to straighten the hair in one pass.
  • Only utilize low temps if you don’t have heat protection. As a result, caution should be exercised.

02. Dividing hair into separate sections

If you have thicker hair, you will need more pieces of hair. In contrast, persons with thick hair may need many more portions. The only exception is one portion of the lowest layer, which you may clip out of the way.

Step2: Dividing hair into sections


  • You’ll be dealing with hair that’s between 2.5 and 5 centimeters (2.5 to 2.5 inches) thick. One lock at a time can be held in a section if it’s handy to do so.
  • Make a half-ponytail out of the top part of your hair by raising and clipping it up. In order to do this, you’ll need full access to your scalp.

03. Separating a lock of hair

Separate a 1–2 inch (2.5–5 cm) broad lock of hair from the lowest layer of hair. Small enough so that you can wrap a flat iron around it with ease, and straighten it in a single pass.

04. Clamping the iron above the roots

2.5-7 cm above your hairline, use a flat iron. Two hot sides should be placed side-by-side with the hair in between. Over-straightening can harm the roots of your hair or burn your scalp if you do it too near to your scalp.

The second time around, if the lock of hair isn’t straight after the first effort, give it a little more time to settle. If the problem persists, try using smaller hair strands or increasing the iron’s temperature.

Remove the pins from the next area and repeat. Begin from the base of the hair and work your way up to the top.


  • The use of low-temperature irons repeatedly can do more harm than using a high-temperature iron only once.
