Practical guidance

How to use

Stored product directions

Manufacturer’s Instructions Shampoo the hair without conditioning, then towel-dry thoroughly. Apply 1–3 pumps of K18 Leave-In Molecular Repair Hair Mask, adjusting the amount for your hair’s length and density. Work the product through the hair, beginning at the ends and moving upwards. Leave for the full four minutes without rinsing, then style as usual. Radiant Eden Expert Tip For the best results, use K18 after a clarifying shampoo to remove product, oil and mineral build-up that could prevent the treatment from penetrating effectively. Do not apply conditioner before K18, and always allow the treatment to work for the full four minutes. If your hair needs additional softness or moisture, apply your usual conditioner or hair mask directly over the K18 after the four-minute waiting time. Leave it on for the recommended time, then rinse thoroughly and style as normal.
