K18 Leave-In Molecular Hair Mask - 1.7oz

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.

Here’s how I tell clients to use it: on clean, towel-dried hair, skip the conditioner, work it through, wait four minutes, then style as usual. Every wash for the first few weeks, then taper off. We use K18 behind the chair at Reverie Salon in River North after big color and lightening work — ask us about it at your next Chicago appointment.
