The Master Guide To Flat Iron Temperatures!

Welcome to the definitive guide on mastering flat iron temperatures! In this comprehensive guide, we'll explore the world of our irons, their unique features, and most importantly, how to achieve salon-quality results by harnessing precise temperature control.

First, here is your quick guide on temperature control:

  • 450°F: Ideal for very thick and stubborn hair types, ensuring a flawless finish.
  • 370°F - 410°F: Perfect for coarse or textured hair, gradually increase temperature until you achieve your desired look.
  • 350°F - 370°F: Maintain healthy hair for naturally wavy tresses.
  • 330°F - 350°F: The go-to range for normal hair types that respond well to heat styling.
  • 250°F - 300°F: Fine hair requires less heat; start at the lowest temperature to prevent damage.
  • Below 160°F: Synthetic hair is delicate, so handle with care and start at the lowest setting.

Now that you have the basics down, which styler is best for you?


For Very Thick and Stubborn Hair (450°F) & Coarse or Textured Hair (370°F - 410°F):

Recommended Flat Iron: The TI Plus Titanium Styler is the ideal choice in this category. With a temperature range that goes up to 450°F, it can handle even the thickest and most stubborn hair types, ensuring a flawless finish.

For Naturally Wavy Hair (350°F - 370°F):

Recommended Flat Iron: The Platform Signature Pro Iron is a great choice. It offers precise temperature control within the recommended range to maintain healthy hair while achieving smooth, straight styles.

For ‘Normal’ Hair (330°F - 350°F):

Recommended Flat Iron: The Platform Plus Iron is also an excellent option for normal hair types. Its adjustable temperature settings fall within this range, making it versatile and suitable for everyday styling.

For Fine Hair (250°F - 300°F):

Recommended Flat Iron: The Flirt Soulmate Styling Iron 1" can be adjusted to lower temperature settings, making it suitable for fine hair. Its titanium plates infused with magnesium provide gentle, efficient styling.

For Synthetic Hair (Below 160°F):

Recommended Flat Iron: The Platform Signature Pro Iron is a safe choice for synthetic hair. It starts at 140°F, ensuring you stay well below the recommended temperature range for synthetic strands.

Bonus Iron -The Curve: For when your hair is straight, but you want a bit of a curl!

The Curve gets its name from its shape. Its beautiful curved design makes it incredibly ergonomic, fitting right to the curve of your hand. The unique curvature of the plates also allows the hair to glide effortlessly - allowing you to smooth, curl or wave hair in half the amount of time.
