Joico K-Pak Colour Therapy Lustre Lock Treatment - 500ml

Colour-Protecting Treatment That Repairs and Strengthens in One Step

Joico K-Pak Colour Therapy Lustre Lock Treatment is a high-performance in-salon or at-home treatment designed to do two important jobs at once — protect your colour and repair your hair. The results behind it are impressive: it retains over 82% of hair colour for up to 8 weeks, increases hair strength by 9 times instantly, and delivers twice the shine for a glossy, radiant finish. If you colour your hair regularly and want to keep it looking vibrant and feeling strong between appointments, this 500ml treatment is a serious investment in the long-term condition of your hair.

Retain Over 82% of Your Hair Colour for Up to 8 Weeks

Colour fade is one of the most frustrating parts of maintaining coloured hair, particularly for anyone who invests in regular salon appointments. The Lustre Lock Treatment is specifically formulated to lock colour in for longer, retaining over 82% of hair colour for up to 8 weeks with regular use. That kind of colour retention makes a visible difference to how fresh and vibrant your colour looks over time, and means you can go longer between appointments without your colour looking dull or washed out.

9x Stronger Hair from the Very First Use

Colour-treated hair is more vulnerable to breakage and damage than unprocessed hair, which is why the repair benefits of this treatment are just as important as the colour protection. The formula increases hair strength by 9 times instantly from the first application, helping to rebuild and reinforce the hair structure that the colouring process can compromise. Alongside this, it repairs and strengthens damaged hair over time, leaving it feeling noticeably healthier, more resilient and easier to manage with every use.

How to Use Joico K-Pak Colour Therapy Lustre Lock Treatment

Apply generously to clean, damp hair from mid-lengths to ends after shampooing. Leave for the recommended processing time before rinsing thoroughly. For best results, use regularly as part of the K-Pak Colour Therapy haircare routine alongside the Colour Therapy Shampoo and Conditioner. The 500ml size is ideal for both salon use and for clients who want a long-lasting supply at home.
