How do you use the K18 Leave-In Hair Mask and Bonding Oil?
Use the two products in order: first the mask, then the oil when styling. This way you get the most from both products.
Wash your hair as usual but skip the conditioner.
Pat your hair dry with a towel until it’s well squeezed out.
Work a small amount of K18 Leave-In Molecular Repair Hair Mask through your hair. Use more if your hair is longer or thicker.
Leave the mask in without rinsing it out.
Comb your hair and continue styling.
Apply Olaplex N.7 Bonding Oil on wet or dry hair for shine and protection.
If you often use heat to style, the Heatbounce Conditioning Heat Protectant from K18 is a great addition to this set. It protects your hair during blow drying or styling and helps your repair results last longer.
Why does this combination work so well on damaged hair?
After a few uses your hair feels noticeably softer and breaks less easily. The mask works from within and reconnects broken bonds in the hair structure. These bonds get damaged by bleaching, colouring or heat.
The oil works on the outside, making your hair smoother, shinier and easier to comb. Together mask and oil deliver a result you can see and feel. Curious about other K18 products? Check out the full range.
Does the K18 Leave-In Molecular Repair Hair Mask need to be rinsed out?
No, you don’t rinse out the mask. Leave it in to work and then simply comb and style your hair.
By not rinsing it out, the active ingredient stays in your hair and can do its job. Follow with Olaplex N.7 Bonding Oil for extra shine and protection.
Do you use conditioner before the K18 mask?
No, you don’t. K18 specifically advises skipping conditioner.
Conditioner coats hair, which can stop the mask from penetrating properly. So wash with shampoo only, towel squeeze well, then apply the mask.
Can the Olaplex N.7 Bonding Oil be used before blow drying?
Yes, it can. The oil protects your hair up to 232 °C, which covers most blow dryers and straighteners.
Apply the oil on wet or dry hair before styling. It doesn’t weigh hair down or make it greasy, and gives instant shine. Note: the oil contains silicones. If you consciously choose silicone-free products, keep this in mind.
Who is this set best for?
This set is made for people who want to actively repair and protect their hair. If you colour or bleach regularly, you’ll notice the difference after a few uses. Use the mask after every wash and combine it with the Bonding Oil when styling for the best result.
If you prefer a bigger set with more product, the Damage Repair Service Set is a good option. If you only need the mask without oil, you can also check single K18 products in the Damaged Hair collection. The combo set is smartest if you want to combine both steps in one routine.
