K18 sells peptide hair care products to reverse hair damage.

K18 earns strong reviews and, for many, clearly works: the Leave-In Molecular Repair Hair Mask, hair oil, and AirWash dry shampoo boost softness, shine, frizz control, and visible repair, especially on bleached or heat-damaged hair. Reviews also flag weaknesses—some find the mask inconsistent or heavy/clumpy if overused, shampoos can feel harsh, AirWash leaves starchy residue and limited longevity, and scent or formula shifts can disappoint—making results technique- and hair-type dependent.

K18 Repair + Protect Mini Hair Set rebuilds damaged hair and defends against heat. This limited-edition duo features a leave-in molecular repair hair mask that reverses damage in four minutes, alongside a conditioning heat protectant. The heat protectant shields hair up to 450°F (232°C), contributing to 85% less breakage after blow-drying. These products restore strength, softness, and bounce, leveraging patented K18PEPTIDE™ technology and Resilicore Heat-Shielding Technology.
