Many flat irons offer a wide temperature range. That range is there to give you control, not to suggest that the highest setting is best. Hair condition, texture, the size of your sections and your technique all affect the result.
The Milano’s five settings
The Laurenza Milano offers 320°F, 360°F, 390°F, 430°F and 460°F. Its temperature memory recalls the last setting used, so check the setting each time before you begin. There is no single temperature that is right for everyone, and a number alone cannot guarantee a safe or effective result.
The American Academy of Dermatology recommends using flat irons on dry hair at low or medium heat, no more often than every other day. It also notes that excessive heat can damage hair regardless of hair type. Treat that as a reason to begin conservatively.
A lower-heat starting routine
- Make sure hair is fully dry and gently detangled.
- Use a heat protectant if it fits your routine, following its label.
- Choose a lower available setting and let the tool reach it.
- Try one small section with a smooth, continuous pass.
- Let it cool, then assess the result before changing the setting.
If a result does not hold, look at your section size and technique before increasing heat. Avoid dwelling in one place or repeatedly pressing the same strand. If your hair is fragile, recently processed or already breaking, consider asking a qualified stylist or dermatologist for advice specific to you.
More heat is not a shortcut
The highest temperature is part of the tool’s range, but it is not an everyday recommendation. A wide plate can help you cover longer or fuller sections, yet that advantage does not remove the need for careful heat use. Keep the plates away from skin and water, and always unplug the iron after styling.
Your best setting is the lowest one that produces the look you want with a controlled technique. If you’re new to the Milano, pair this guide with our straightening routine or curling tutorial.
