Operating Instructions
K18 Leave-In Molecular Repair Hair Mask
Apply to clean, damp, towel-dried hair.
- Start with 1 pump of the mask. Add more as needed based on your hair length, thickness, and condition. Refer to the dosage chart below for guidance.
- Distribute the mask evenly throughout your hair, from ends to roots.
- Wait 4 minutes before styling or applying any other hair products. Do not rinse out the mask.



K18 Weightless Hair Strengthening Oil
Apply to damp or dry hair.
- Start with 1-3 drops of the oil. Build up the amount as needed, depending on hair type and desired results.
- For strengthening benefits and frizz reduction, apply to damp hair.
- For smoothing frizz, flyaways, and adding shine, apply to dry hair.
- Distribute the oil evenly through the mid-lengths and ends of your hair.


Maintenance
Proper care and storage will help maintain the efficacy of your K18 products.
- Store both the Hair Mask and Hair Oil at room temperature, away from direct heat, sunlight, and humidity.
- Ensure that the caps are tightly closed after each use to prevent air exposure and product degradation.
Troubleshooting
Hair feels heavy or greasy after using the K18 Mask:
The K18 Mask is highly concentrated. You may be using too much product. Reduce the number of pumps used per application. Start with the minimum recommended amount for your hair type and length.
Not seeing desired results from the K18 Mask:
Ensure you are applying the mask to clean, towel-dried hair (not dripping wet) and waiting the full 4 minutes before applying any other products or styling. It is crucial to avoid using conditioner before the mask, as this can create a barrier that prevents the K18PEPTIDE™ from penetrating effectively.
K18 Oil makes hair feel oily:
The oil is concentrated. Start with fewer drops (1-2) and apply primarily to the mid-lengths and ends of your hair, avoiding the scalp if you are prone to oiliness. Adjust the amount based on your hair's needs.
