Step 1: Remove plastic 3 pin plug protector

Step 2: Unravel the twist ties that organise the cable

Step 3: Remove the protective heat guard

Step 4: Remove the clear protective film from digital touch pad

TIP - start at one corner of the digital pad and gently lift it with your fingernail. Once you have a small section lifted, the film will come away easily and in one piece. Please see video for guidance.

Your Iron is now prepped and ready for use.

Step 1: Start with dry hair.

Step 2: Shake your CLOUD NINE Magical Quick Dry Potion heat protector spray to activate the lightweight conditioners, then spritz your hair to provide heat protection.

Step 3: Section your hair and secure it with CLOUD NINE Croc Clips.

Step 4: Select your temperature using the temperature control switch below the Floating Ceramic Plates. Temperatures range from 100-200°C. Variable Temperature Control provides a range of settings for a range of hair types. Style at lower temperatures for optimum hair health. Use the Temperature Calculator to discover the best heat setting for your straighteners.

Step 5: Smooth the Slim Iron through each section of your hair from root to tip. Our plates are infused with minerals that work miracles. Sericite and Tourmaline help to seal the cuticle and lock in moisture for shinier hair.

Step 6: Repeat section by section or just use to touch up. The Slim Iron has Floating Ceramic Plates designed to care for your hair, not clamp. Expertly designed with Spring-Flex Technology™, the plates adjust when closed, cushioning the impact of styling and preventing split ends.

Step 7: Brush through your hair to smooth flyaways. The CLOUD NINE Luxury Dressing Brush is perfect for finishing off your style.

Does the Slim Iron have an automatic turn-off?
The CLOUD NINE Slim straighteners come with an automatic switch-off function. After 30 minutes of inactivity, this slim straightening iron powers off to protect your surfaces from heat damage. Your style. Made safer.

What is the size of the plates on the Slim Iron?

The flat plates on the Slim Iron are ½ inch wide, but the body of the straightener is full-size. These smaller, thinner plates mean Slim Irons makes the perfect fringe straighteners, or precision solution for styling shorter hair. You can also use the Slim Iron for styling tighter curls. Check out our styling guides for ideas and inspiration.


How do I know when my Slim Iron is ready to use?

Your Slim Iron is ready to use when its green light starts flashing and 150°C is illuminated. Switch to a higher temperature by pressing the temperature control button and waiting for the flashing green light to pause next to the desired temperature. 


What temperature should I use my Slim Iron at? 

Our Slim Iron has Variable Temperature Control which means you can use the temperature most suited to your hair type. Head to our Temperature Calculator to find out more.


How should I store my Slim Iron?

For storage, we recommend keeping the plug of your CLOUD NINE hair straightener away from the plates to avoid scratching. Do not wrap the cord around the iron. Only put your iron away when the plates are cool. Use the Protective Iron Heat Guard to prevent heat damage to your surfaces while you wait.


What makes the CLOUD NINE Slim Iron the best slim straightener for short hair?

The CLOUD NINE Slim is unlike other small straightening irons because it is a full-size tool with smaller, thinner plates. Slim hair straighteners for short hair often have a small, non-ergonomic handle. The CLOUD NINE Slim iron allows you to create a precision style while keeping a secure grip thanks to its larger handle. These slim hair straighteners are also packed with unique CLOUD NINE features and benefits to promote happier, healthier hair.
