Not sure which K18 products you need or what order to use them in? The K18 routine is actually much simpler than it might seem.

The range is designed around three simple steps: cleanse, repair and style. You don't need to use every product every time you wash your hair. The most important thing is knowing when to use the K18 Leave In Molecular Repair Hair Mask and when to use your K18 Damage Shield Protective Conditioner.

Here's your simple K18 routine.

Step 1: Shampoo

Start with clean, damp hair.

For regular washing, use K18 Damage Shield pH Protective Shampoo to gently cleanse away dirt, oil and everyday buildup.

If your hair is feeling heavy, sticky or has a lot of product buildup, use K18 Peptide Prep Detox Shampoo instead for a deeper cleanse.

Once you've shampooed, gently towel dry your hair.

Step 2: Choose Your Treatment

This is where your routine changes depending on whether you're using the K18 mask.

Using the K18 Mask? Skip conditioner.
Apply K18 Leave In Molecular Repair Hair Mask to clean, damp hair. Start with 1 to 3 pumps and work through the hair, focusing on the areas that need it most. Wait 4 minutes, then you're ready to style. Don't rinse the mask out or apply conditioner.

Not using the K18 Mask?
Use K18 Damage Shield Protective Conditioner. Simply shampoo, then follow with your K18 Damage Shield Protective Conditioner before styling.

The easiest way to remember it is:
K18 Mask = Skip Conditioner.
No K18 Mask = Use K18 Damage Shield Protective Conditioner.

For best results, use the K18 Leave In Molecular Repair Hair Mask for 4 to 6 washes following a salon service, such as colouring, bleaching or other chemical treatments. After those initial 4 to 6 washes, continue using the mask as needed to maintain your hair's condition and help manage ongoing damage.

Step 3: Style + Control Frizz

Once you've finished your treatment, you're ready to style.

The K18 Molecular Repair Hair Oil can be used on damp hair before heat styling, on dry hair for extra shine and frizz control, or both.

Start with just 1 to 3 drops and add more if needed.

If you regularly use heated styling tools, the oil also provides heat protection, making it an easy addition to your styling routine.
