01. Abstract
The transition from traditional alkaline-based hair smoothing to Acid-Thermal Polymerization represents a paradigm shift in trichological science. Diamond V6.0 utilizes a proprietary Tannic-Sulfur Hybrid matrix to achieve structural realignment in Type 4C hair without the irreversible cortical damage associated with formaldehyde or high-pH relaxers.
This paper details the molecular mechanisms of action, the thermal phase transition peaks, and the resulting physical properties of the treated fiber.
02. The Challenge: Type 4C Morphology
Type 4C hair fibers are characterized by an asymmetric, curved follicle geometry resulting in an elliptical cross-section with high cortical density.
- —Cortical Resistance: 4C hair has a 20% higher concentration of disulfide bonds per square micron.
- —Cuticle Overlap: Denser cuticle tiling makes standard molecule penetration inefficient.
03. Mechanism I: Acid-Mediated Dilation
Diamond V6.0 rejects the use of alkaline swelling agents (pH 9.0+). Instead, it operates at a targeted pH of 3.0 – 3.5.
"By operating below the isoelectric point of keratin (pH 4.5), the V6.0 formula creates an osmotic differential. This 'Sub-Osmosis' allows low-molecular-weight Tannic Acid to bypass the cuticle barrier uniformly."
04. Mechanism II: The Polyphenolic-Sulfur Bridge
Hybrid Synergy
Tannic Acid + L-Cysteine InteractionTannic Acid
Acts as a multi-valent cross-linking agent that forms stable complexes with existing keratin proteins through hydrogen and ionic bonding.
L-Cysteine
Provides active thiol (-SH) groups that repair gaps in the hair’s internal sulfur bridges, granting molecular elasticity to the realignment.
05. Mechanism III: Thermal Phase Transition
The "Diamond Alignment" is achieved through a controlled Thermal Phase Transition at 230°C (446°F).
Under the activation of calibrated heat, the Tannic-Cysteine hybrid undergoes a dehydration reaction, essentially "curing" the hair fiber into a new straight geometry while simultaneously locking in structural repairs.
