Simultaneously strengthen and shield locks from harmful heat damage with the Colour Therapy Lustre Lock Multi-Perfector Daily Shine and Protect Spray from Joico’s K-Pak range; a dual-phase leave-in spray that fuses the hydrating benefits of exotic oils with a unique, damage-control formula. Creating a lotion-like dose of nourishment with every shake of the bottle, the formula locks in more than 89% of colour vibrancy after ten shampoos and deeply strengthens strands, reducing the appearance of split ends and frizz.
