How To Straighten Hair Like a Pro

1.Pick the right size flat iron
For short, thick or fine hair: Use an iron with narrow plates ranging in size from half-an-inch to one-inch thick.
For long, thick or fine hair: Use an iron with wider plates ranging in size from one-and-a-half inches to two-inches wide so you’re able to cover more surface area in less time.
2.Select the right heat setting
Try to get the temperature somewhere between 160°C and 180°C (320°F to 356°F).
3.Get a super straight look
Sections near the crown of your head, lift hair off your scalp and get the iron as close to your roots as possible, pressing firmly while drawing the iron straight outward from your head to achieve a flat, smooth finish.
