this is the one the colourists actually keep on the shelf. it is a leave-in, not a rinse-out — shampoo without conditioner, towel dry properly, one to three pumps depending on length, wait four minutes, then style. you do not rinse it. four to six washes after a colour or chemical service, then as needed.

the active is k18's own sh-oligopeptide-78, listed on the box as K18PEPTIDE™, sitting in a short formula with hydrolyzed wheat protein and wheat starch. the brand's claim, printed on the carton, is repair of damage from bleach, colour, chemical services and heat in four minutes.

full ingredient list is on the box and reproduced below, because anyone buying a leave-in wants to read it before it touches their hair.
