Everyone has their favourite product, but our award-winning, Joico K-PAK Deep-Penetrating Reconstructor has a loyal following that’s truly unparalleled. The reason? In just five minutes (The 5-minute miracle!), this powerful combination of amino acids rebuilds and re-fortifies stressed strands… returning hair to its former glory in a single application.

Perfect choice for: Hair – of any texture, length, or thickness–that’s become damaged, dry, and dull, thanks to relentless exposure to thermal styling tools, chemical processes, or a harsh environment.

Here’s how: Apply to damp, towel-dried hair; allow to penetrate for a full five minutes; then rinse. (Tip: Leave on even longer for an added treat for your hair – your hair will thank you for it.) You’ll feel the difference before you even pick up your blowdryer.

The inside secret: We added the highest concentration of Quadramine Complex, our famous protein-stocked repair formula, to maximize protection and reconstruction to each and every damaged strand.
