This is a leave-in repair mist from K18's professional line, sold to salons and used as the first step of the K18REPAIR service before a color or chemical treatment. It sprays onto dry, sectioned hair and is left in for about 4 minutes, no rinse, to help the following service apply and perform better and to make hair more resilient. It is a pro-exclusive companion to the K18 PRO mask, not a standalone retail styler, so home users are better served by K18's retail leave-in mask. Reviewers rate it highly for how it preps hair before salon services.

Reviewers rate it highly and mostly praise it as a salon prep step that leaves hair feeling stronger and ready for color or chemical work. Criticism is limited, mostly about it being a pro product that is awkward to use at home.
This is a leave-in, lightweight repair mist for professional use. It repairs existing damage and makes hair more resilient before salon services. It works in 4 minutes and comes in a spray-on format.
The mist uses K18PEPTIDE, a biomimetic peptide that reconnects broken polypeptide chains at the molecular level. This also reconnects disulfide bonds to reinforce hair along its length and width. Because it works at the molecular level, it is effective on all hair types. It is made without emollients, so it does not interfere with chemical and color services.
It is the first part of the K18REPAIR service, which pairs the PRO mist with the PRO mask. Used before services, it helps prevent damage during them and helps color last longer and fade slower when paired with at-home K18 mask use.
