Beyond Hydration: How DropCare® Hydrolyzed Keratin Rewrites Hair Repair Science

The Core Revelation
Human hair is 80-90% keratin – a protein fortified by disulfide bonds (S-S bridges) that grant elasticity and strength. Yet chemical damage ruptures these bonds, causing:

• ⚠️ 12-13% moisture loss (vs. healthy hair)

• ⚠️ Cracked cuticles exposing cortical proteins

• ⚠️ Reduced light reflectance (dullness)

Enter DropCare^® Hydr-KP (powder) and Hydr-KPL (liquid) – engineered keratin solutions that rebuild hair from within.

3 Mechanisms of Action

1. Structural Reconstruction

   • Binds to exposed cysteine residues via hydrogen bonds

   • Reforms disulfide crosslinks in cortex (SEM-proven):

     • 5% concentration: 40% cuticle closure

     • 20% concentration: 95% cuticle repair

2. Moisture Lock
   Restores water-holding capacity by 63% (vs. bleached hair):
   Bleached hair recovers 80% hydration after keratin treatment (Barba et al.)

3. Lipid-Protein Matrix Restoration
   Replenishes ceramides & fatty acids lost during damage:

   • 17.8% cysteine recovery

   • 11.7% serine regeneration

The Future of Hair Repair
As China’s haircare market grows at 4.6% CAGR (reaching ¥53.48B in 2022), keratin emerges as the ultimate "multi-functional active" – bridging protein loss repair, lipid restoration, and cuticle regeneration in one molecule.
