The Diffon DF1 5000 and Diffon Supreme Ionic XL are curly hair dryers with built-in diffusers that cater to the needs of wavy, curly, and coily hair types (Type 2, 3, 4). With their unique features and benefits, these hair dryers aim to define curls, reduce frizz, and minimize heat damage, while also offering a faster drying experience compared to air drying.

The Diffon DF1 5000 is a lightweight and compact 2-in-1 diffuser and blow dryer, making it more travel-friendly than a hair dryer with a separate attachment or cap. Its Easy Hold Handle ensures a comfortable and quick drying experience. The Diffon Supreme Ionic XL, on the other hand, boasts a larger 6.5-inch wide diffuser bowl and an 8.6-inch length, providing ample coverage for longer and thicker wavy, curly, and coily hair.

Both hair dryers feature Ceramic Argan Oil technology, which helps to reduce heat damage and add hydration and shine to the hair. The Curl Booster System, present in both models, gently dries curls without frizz through even air diffusion, thanks to a microperforated grid, 112 air outlets, and 12 fingers.

The Diffon DF1 5000 offers 2 combined air/heat settings, while the Diffon Supreme Ionic XL provides 2 air flow settings and 3 heat settings, giving users more control over their styling preferences. The Diffon Supreme Ionic XL also boasts a Cool Button and Digital Temperature Control, adding to its versatility.

The Ionic Care Technology, exclusive to the Diffon Supreme Ionic XL, helps to further enhance the definition and smoothness of curls, while the Curl Booster System in both models ensures faster drying times compared to air drying and more effective results than regular diffuser attachments.

Customer reviews for the Diffon DF1 5000 and Diffon Supreme Ionic XL have been positive, with average ratings of 4.5 out of 5 stars (619 reviews) and 4.3 out of 5 stars (291 reviews), respectively. Customers have praised the hair dryers' ability to define curls, reduce frizz, and minimize heat damage, as well as their ease of use and travel-friendly design.

If your Diffon hair dryer won't turn on, it's likely due to the built-in safety switch being activated in the plug. To reset, simply unplug the device and then push the red reset button on the plug until it clicks. Once done, you can plug it back in, and the Diffon should power on as expected.
