【The Triple-Action Strand-Plumping Catalyst: Root Fortification, Dimension Boost, & Micro-Repair】

• Vitamin B7 Biotin (The Root Catalyst): Infused with therapeutic-grade Biotin, a critical nutrient specialized in optimizing keratin infrastructure. It deeply penetrates individual hair follicles to fortify hair roots from within, dramatically reducing premature hair fall and breakage due to brittle texture.

• Hydrolyzed Collagen Matrix (Visual Thickness Amplifier): Rich in micro-molecular Hydrolyzed Collagen proteins that coat every single strand. This unique science locks moisture in and plumps up the individual diameter of each hair shaft, structurally lifting the root to yield an instant 3D bouncy, airy, and voluminous texture that maximizes visual density.

• Hydrolyzed Wheat Protein (Elasticity Restorer): Features natural wheat amino acids that tunnel into the porous core of damaged hair cuticles. It effectively treats structural voids, reinforcing the hair's horizontal tensile strength and imparting a brilliant, healthy, and highly seductive sheen.

【The Strict Eco-Healthy Hair Care Commitment】

• 100% Sulfate-Free Surfactants: Completely rejects harsh, synthetic lathering agents like SLS or SLES that strip away organic scalp hydration, cause persistent dry flaking, and accelerate follicle death. OGX utilizes gentle, planet-friendly coconut-derived cleansers to clean deeply while respecting your natural sebum balance.

• Paraben-Free Clean Standard: Free from dangerous synthetic preservatives, making it completely color-safe, chemical-treatment friendly, and perfect for individuals navigating highly sensitive scalp microclimates.
