PRODUCT DESCRIPTION

The Molecular Power Routine for Damaged Hair

Stop patching damage and start reversing it. This curated trio is the definitive solution for hair compromised by bleach, color, chemical services, and heat. Powered by the patented K18PEPTIDE™, this system works at the molecular level to reconnect broken polypeptide chains—restoring strength, elasticity, and softness in just 4 minutes.

What’s Inside:

  • PEPTIDE PREP™ Detox Shampoo (250ml): A color-safe, deep cleanser that removes 99% of product buildup, 95% of sebum, and 76% of copper. It clears the path so the K18PEPTIDE™ can penetrate effectively.

  • Leave-In Molecular Repair Hair Mask (50ml): The cult-favorite treatment that repairs hair damage from the inside out. No rinsing, no fuss—just 4 minutes to "like-new" hair.

  • PEPTIDE PREP™ pH Maintenance Shampoo (250ml): The perfect daily cleanser. pH-optimized to keep the hair cuticle closed during washing, protecting your hair’s natural moisture and shine.

The Problem It Solves:

  • Structural Damage: Rebuilds hair that feels "mushy" or brittle from over-processing.

  • Product Buildup: Removes the "film" that makes hair look dull and heavy.

  • Elasticity Loss: Restores the bounce and "snap-back" to hair fibers.

Prep: Wash with the Detox Shampoo. Do not use conditioner.

Repair: Towel dry thoroughly. Apply 1–3 pumps of the Molecular Repair Mask. Wait 4 minutes. Do NOT rinse.

Maintain: On your next wash, use the pH Maintenance Shampoo to keep your results locked in.
