One Pass Flat Iron
- How to use
best flat iron for healthy hair
The new and improved Bio Ionic® OnePass® Styling Iron uses patented silicone strips and Bio Ionic Moisturizing Heat™ Technology to deliver smooth, shiny, healthy-looking styles—in just one stroke.
See and feel the difference with this revolutionary iron that’s powered by NanoIonic™ MX, a proprietary complex of natural minerals that infuses moisture back into hair while you style. This ensures strands stay smooth, hydrated, and frizz-free.
The silicone speed strips deliver one-pass styling from root to tip by gently gripping the hair, rather than clamping hair in between the plates. Smoothing and straightening without pulling, snagging, or breaking strands.
The result is smooth, long-lasting styles and hair that is healthier, softer, and shinier—the way nature intended.
- Digital temperature control up to 450 degrees F / 230 degrees C
- Rapid heat up time and consistent heat delivery
- Ergonomic design and 9'ft swivel cord
- Universal voltage and 1-hour auto shut off
- Temperature memory resets to last set temperature when re-powered
- 1 year warranty through Hair Holistic and 4 years warranty after that through Bio Ionic
Directions for Use
Best used with a heat protection product such as Hair Love Prep Spray or Serenity Smoothing Cream.
Apply Hair Love Prep Spray or Serenity Smoothing Cream to the hair, then use light pressure as you glide through the hair. This will smooth the cuticle without stretching your hair and lock in the style.
Best for straight styling with increased shine, one pass styling on all hair types.
