Key features of the BIO IONIC Long Barrel Curling Iron.
Curling Your Hair
- Ensure your hair is dry and detangled.
- Section your hair into manageable portions. The 0.75-inch barrel is designed for creating tight curls and spirals.
- Open the clamp and place a section of hair between the clamp and the barrel, starting near the roots or mid-shaft depending on your desired style.
- Wrap the hair around the barrel, away from your face, ensuring the entire strand is evenly distributed. The extended barrel is particularly beneficial for longer hair.
- Hold for a few seconds (typically 5-10 seconds, adjust based on hair type and desired curl intensity).
- Release the clamp and gently slide the curling iron out, allowing the curl to set.
- Repeat for all sections of hair. For a softer look, gently run your fingers through the curls once they have cooled.

The extended barrel allows for wrapping more hair per section, reducing styling time.
Moisture Heat Technology & NanoIonic MX
This curling iron incorporates NanoIonic MX and Moisturizing Heat Technology. NanoIonic MX helps micronize water molecules, allowing them to penetrate the hair for enhanced hydration and conditioning. This technology, combined with moisturizing heat, locks in moisture and seals the cuticle, resulting in long-lasting, hydrated, and bouncy curls that are visibly smoother, softer, and shinier.

Maintenance
- Cleaning: Ensure the curling iron is unplugged and completely cool before cleaning. Wipe the barrel and handle with a soft, damp cloth. Do not use abrasive cleaners or immerse the appliance in water.
- Storage: Store the curling iron in a cool, dry place, away from moisture and direct sunlight. Ensure the cord is not wrapped tightly around the appliance, as this can cause damage.
Troubleshooting
- Appliance not heating: Ensure the curling iron is properly plugged into a functioning electrical outlet and the power button is pressed. Check if the power outlet is working by plugging in another device.
- Curls not holding: Ensure the correct temperature setting is selected for your hair type. Allow curls to cool completely before brushing or styling. Consider using a heat protectant and a light-hold hairspray.
- Hair snagging: Ensure hair is completely detangled before curling. Do not wrap too much hair around the barrel at once.
