K18 Repair Mist is a leave-in spray built on the brand's peptide technology, which it says reconnects broken keratin chains rather than coating the surface. It is a lighter, no-rinse format than the K18 leave-in mask, aimed at fine or thin hair and at quick top-ups between washes. Fans of the mask line report similar softness and less breakage; skeptics note the line is expensive per use and that results build over time rather than after one spray.

Owners of the K18 line generally praise the mist for softness and reduced breakage without weight, especially on fine hair. Critics say it takes weeks of consistent use to see a difference and that the brand's pricing is hard to justify for a light spray.
K18 Repair Mist is a lightweight leave-in hair mist made with patented peptide technology. It repairs broken keratin chains to help restore hair damaged by bleach, coloring, chemical treatments, heat and styling tools.
The mist adds moisture and a protective barrier against environmental stressors without weighing hair down. It improves softness, bounce and manageability, and it reduces breakage, split ends and color fading. Its results don't wash away with shampoo. It is made for all hair types.
To use it, start with clean, thoroughly towel-dried hair. Section the hair and apply 2 to 6 sprays per section, working it in. Leave it on for 4 minutes without rinsing. Then dry and style as usual, with or without heat. Shampoo your hair, but skip the conditioner.
