 How To
  1. Start with hair that is completely dried & detangled before using Le Duo Flex.
  2. When initially plugged into an electrical outlet, the lights on the tool will illuminate in succession from the fan icon to the highest temperature (the tool has not started heating).
  3. To heat Le Duo Flex up for the first time, press and hold the power button until a white light illuminates beside 280°F.
  4. The light beside the default temperature of 280°F will blink while the tool heats up. Once the tool has reached temperature, the white light beside the temperature will stop blinking and the fan will turn on automatically.
  5. To select a different temperature, press and release the power button until the light beside your desired temperature illuminates. 
  6. To deactivate the fan, press and release the fan button.
  7. Apply your L’ange heat protectant of choice.
  8. Detangle and divide hair into small, manageable sections.
  9. Make sure to keep the hot plates away from your face and body. 
  10. For tight curls, toggle the adjustor switch—found above the clip—towards the tight-curl symbol. For loose curls, toggle the adjustor switch towards the loose-curl symbol. 
  11. Holding the iron vertically, squeeze the clip to open the plates and insert a 1⁄2”–1” section of hair between the plates near the root.
  12. Close iron, rotate between 180° and 360°—the more rotation, the tighter the curl—making sure that you turn the tool in the direction of the curve of the plate. Glide the iron down the length of the hair. The slower you pull the iron, the tighter the curl. Consider varying the curl direction for a more natural end result.
  13. Repeat on remaining sections until your desired style is achieved.
  14. Once finished, press and hold the power button for 3 seconds to turn OFF the tool. All lights on the handle will turn off. 
  15. Unplug Le Duo Flex and wait until completely cooled before storing away.

Frequently Asked Questions:

1. What is the difference between the Le Duo Classic and Le Duo Flex? Le Duo Classic and Le Duo Flex are both versatile airflow titanium styling tools, but they have key differences. Le Duo Classic is a 2-in-1 straightener and curler available in two sizes, ideal for sleek straight styles and soft curls. In contrast, Le Duo Flex, available in one size good for all hair lengths, is designed specifically for creating both loose and tight curls, featuring a patent-pending tension switch to adjust curl definition, an optimally placed negative ion generator for frizz-free results, and curved titanium plates to enhance curl formation effortlessly. 2. How do you switch between the 2 curling modes? To switch between curling modes, toggle the tension switch to the top position for loose curls and the bottom position for tight curls. 3. Which heat setting is right for me? Le Duo Flex has five heat settings with a temperature range of 280°F - 430°F. For coarse hair, you may consider starting at 390°F or 410°F. For medium hair, you may consider starting at 360°F or 390°F. And for fine hair, you may consider starting at 280°F or 320°F. For the best hair care, we always recommend using a heat protectant before styling to keep your hair healthy and protected. 4. Is this tool for all hair types? Yes, this tool is suitable for all hair types, thanks to its smooth titanium plates and adjustable heat settings up to 430°F, allowing you to customize the heat for your specific hair needs. 5. Can I use this tool on short hair? Yes, you can use Le Duo Flex on short hair, except very short pixie cuts. 6. How do I curl my hair with Le Duo Flex? To curl your hair with the Le Duo Flex, start by prepping with a heat protectant spray and selecting the appropriate heat setting for your hair type. Decide on your desired curl pattern—loose waves or tight curls—then section your hair into approximately 1-inch sections, which is about the diameter of the tool. Insert a section of hair, rotate the iron between 180° and 360°, and smoothly glide it down. Always ensure you rotate the barrel in the direction of the plate’s curve. The more you rotate, the more defined the curl will be. Finish with a styling spray for hold. 7. Is Le Duo Flex or a wand better for hair styling? Many people appreciate Le Duo Flex for its intuitive design and effortless usability. Its innovative curved plate design makes it incredibly beginner-friendly. The iron does the work for you, adapting to the contour of your hair for effortless styling. Plus, it features 360-degree airflow, which helps set your curls as you style, giving you maximum longevity. Its versatility is another major advantage—you can create a variety of curl patterns, from loose waves to defined curls, all with just one tool. 8. How can I make my styles last longer? For the best results, always style with the fan on—Le Duo Flex’s 360-degree air vents will set your curls for maximum longevity. Its innovative cooling vents automatically help cool your hair to lock in your style. To extend the life of your curls even further, apply a thermal protectant with flexible memory, like Rival Heat Shield, to clean, dry hair before styling. For extra hold, finish with a high-quality hairspray like Hold-All to keep your look in place all day. 9. What does the enhanced negative ion generator on Le Duo Flex do? The enhanced ion generator in Le Duo Flex is strategically placed to release negative ions around the entire cuticle, helping to reduce frizz, smooth hair, and enhance shine by neutralizing positive charges and sealing the cuticle. 10. What are electroplated smooth glide titanium plates? Electroplated Smooth Glide Titanium plates are designed to give you a sleek, effortless styling experience. The electroplating process creates an ultra-smooth surface that glides through your hair with less friction, helping to reduce snagging and damage. Plus, titanium heats up quickly and evenly, delivering fast, consistent results while locking in shine. The result? Smooth, frizz-free styles with less effort! 11. What sizes does the Le Duo Flex come in? Le Duo Flex comes in one size that works for all hair lengths–the only size you’ll need to perfect your look.
