Description

A reparative leave-in mask.

Want hair that looks brand new? Try the K18 Leave-In Repair Mask. Made with K18PEPTIDE™ (a patented bioactive peptide treatment), this leave-in mask is clinically proven to reverse damage in four minutes. Delivering repair from the inside out, this mask works to heal damage caused by bleach, colour, chemical services, heat, and mechanical styling. Offering lightweight moisturising benefits, this no-rinse-needed mask renews the hair’s strength, softness, smoothness, and bounce without weighing it down. With a long-lasting formula that doesn’t wash away with shampoo, this mask minimises breakage, split ends, and colour fading (thanks to its pH balance of 5.0-6.0).
