Perfect choice for: Everyone. And we do mean everyone. Our unique lightweight formula won’t overwhelm fine hair, yet is rich and nourishing enough to have impact on thicker strands. To use it: After shampooing, apply to hair and leave on for a full minute, then rinse and rejoice. For the ultimate treatment follow with K-PAK Deep Penetrating Reconstructor. Benefits: Our exclusive Bio-Advanced Peptide Complex is literally anchored on both ends by Amino Acids that specifically target the damaged areas; Keratin Silicone Complex (it’s wonderfully weightless), locks in moisture, seals that repaired cuticle, and delivers intense shine and smoothness to your newly-protected hair.
