An addition to the brand’s popular K-Pak Color Therapy product line, Luster Lock uses its QuadraBond Peptide Complex of exotic African manketti and argan oils to protect the vibrancy and shine of colour-treated hair. The formula also contains Bio-Advanced Peptide Complex’s hair-identical keratin peptides, which shield hair from damage and strengthen strands for nine times more resistance to breakage. Use Luster Lock in the salon as a service after colour processing by applying it to damp hair and leaving it on for up to five minutes before rinsing thoroughly with warm water. It can also be used on dry hair as a pre-shampoo treatment. Apply between foils or to hair lengths while the base colour is processing before shampooing out. Remember to send your clients home with Luster Lock to continue to transform dry, brittle hair into healthier strands.
