This formula is enriched with Polyquaternium-10, an advanced conditioning polymer that controls hair volume while maintaining a sleek, straight appearance. It incorporates Keratin Associated Proteins (KAPs), structural proteins located between keratin fibers, whose inclusion represents a major innovation in regenerative therapies, significantly enhancing the effectiveness and longevity of semi-permanent straightening treatments. The presence of modified cysteine with an acidic profile acts as a powerful straightening active, promoting the controlled realignment of keratin chains for lasting smoothness. Finally, ceramides with exclusive cellular interlocking technology function as amino acid sealers, reinforcing the internal structure of the hair while restoring the cuticle’s natural hydrophobicity. This dual action not only improves strength and resistance but also enhances shine and provides long-term protection.
