As convenient as it is nourishing for your hair, this bundle brings together two essential steps for restoring your lengths to tip-top condition. Hello, stronger, softer and smoother strands…

First, there’s the Peptide Prep Detox Shampoo — formulated to nourish hair while removing build-up and grime to create a healthy hair canvas. Designed to be used once a week to detox your mane right from the scalp, you’ll find a blend of salicylic acid and activated charcoal unite in this non-stripping lather to unclog hair follicles and banish oils, metals and dirt. Then, there’s the Molecular Repair Hair Mask (15ml), a leave-in treatment packed with the patented ‘K18Peptide’, which boasts a unique sequence of amino acids that penetrate through the struggling strands to reconnect and repair those broken chains. Boasting salon-like results in just 4 minutes, this concentrated formula is brimming with moisture magnets and protectors to leave your hair feeling prepped, primed and voluminous.
