K18 Leave-In Molecular Hair Mask - .5 oz

If I could put one repair product in every client’s hands, it would be this one. The K18 leave-in mask works at the molecular level to reverse damage from color, lightening, heat, and time — in about four minutes, with no rinsing. It isn’t a coating that washes out; it actually repairs the bonds inside the strand, so hair feels stronger, softer, and bouncier the more you use it.

On clean, towel-dried hair, skip the conditioner, work it through, wait four minutes, then style as usual. We use K18 behind the chair at Reverie Salon in River North after color and lightening services.

The 0.5oz is a great travel size, or an easy way to start the K18 routine without committing to the full tube.
