This shampoo and treatment are powered by ultra-deep penetration and adhesion technology, allowing active keratin proteins to bypass the hair’s hydrophobic cuticle barrier to anchor deep inside the hair shaft. The patent-pending Ionic Penetration Technology, developed by I-ne’s R&D institute, utilizes ionic liquid science to deliver concentrated active proteins deep into the hair cortex. This provides high heat thermal defense while locking in hydration for over 24 hours. The formulations also act to solve "shampoo fatigue,” whereby products lose efficacy over time when ingredients fail to pass the cuticle barrier. Amprem instead delivers efficacy with every wash via its proprietary technologies and ingredient concentrations. The products are infused with a velvet nectar scent composed of a multi-layered pyramid of notes. In tests, 94.6% of participants reported a visible transformation in hair strength, core density, and a significant reduction in split ends and strand breakage over the four-week evaluation period.

Product Innovation of Amprem: Amprem redefines high-performance hair care by solving "shampoo fatigue"—the common issue where products lose efficacy over time because repair ingredients fail to pass the "Cuticle Barrier", leaving hair internally dry while coating the outer layer. Amprem delivers sustained, salon-grade transformation with every wash through a combination of proprietary technologies, extreme ingredient concentrations (Keratin), and high-performance formulations.

To scientifically validate Amprem’s structural hair repair, safety, and technological claims, comprehensive clinical trials, instrumental hair measurements, and dermatological evaluations were conducted in collaboration with independent testing institutes. Top 3 Most Relevant Results 1. Internal Cortex Repair & Structural Tensile Strength 94.6% of participants reported a visible transformation in hair strength, core density, and a significant reduction in split ends and strand breakage over the 4-week period. Instrumental strand testing demonstrated an +88% increase in cortex protein retention post-rinse compared to conventional shampoos, confirming that active Keratin and Silk PPTs successfully penetrate the hydrophobic cuticle barrier and anchor inside the hair shaft. 2. 24-Hour Moisture Retention & Humidity Anti-Frizz Shield 92.0% of participants confirmed sustained internal hydration, silky smoothness, and complete elimination of hair dryness throughout the day. Environmental chamber testing (80% relative humidity at 25°C) demonstrated a **-91% reduction in humidity-induced frizz and strand swelling**, maintaining sleek, salon-grade manageability for over 24 hours post-wash. 3. 100% Scalp Safety & Hypoallergenic Tolerance 100% of participants exhibited zero skin irritation, redness, or adverse dermatological reactions during 24-hour human closed patch testing and 4-week clinical monitoring (HRIPT). 96.4% of participants agreed that the formula was exceptionally gentle and non-comedogenic on the scalp, providing high-density cleansing without leaving heavy residue or triggering excess oil production. Supporting Instrumental Lab Benchmarks Cuticle Surface Alignment: High-resolution SEM imaging verified a +98.2% improvement in scale flattening and surface alignment after a single use. Acid-Heat Thermal Defense: Stress testing showed +95.5% enhanced thermal protection during blow-drying and flat-ironing when using the Levulinic Acid-infused Keratin Shot line. Background Target Cohort: 112 female subjects aged 20 to 49 presenting moderate to severely damaged, chemically treated (bleached/dyed), or dry and unruly hair. Duration & Protocol: 28 consecutive days (4 weeks) of daily application under double-blind clinical supervision. Evaluation Framework: Human Repeat Insult Patch Testing (HRIPT), Scanning Electron Microscopy (SEM), cortex tensile analysis, and standardized user perception scoring.

Hair Care Benefits & Performance Hair & Concern Targets: Deeply restores severely damaged, bleached, or dry hair from within the cortex. Completely tames humidity-induced frizz, eliminates unruly wave distortion, and seals split ends without leaving hair feeling weighed down or greasy. Technical Performance: Powered by Ultra-Deep Penetration & Adhesion Technology, active Keratin and Silk proteins bypass the hydrophobic cuticle barrier to anchor deep inside the hair shaft. Delivers high-heat thermal defense while locking in core hydration for over 24 hours. Sensory Experience: The ultra-concentrated gel formula transforms into a dense, friction-free cushion lather. It actively repairs strands during the wash phase, providing an instant tactile signal of density, salon-grade silkiness, and weightless softness. Fragrance Performance & Longevity Perfume-Grade Olfactory Profile: Crafted with fine fragrances (Velvet Nectar & Innocent Magnolia) featuring a multi-layered pyramid that evolves elegantly from vibrant fruity-floral top notes to warm, sophisticated amber and sandalwood base notes. 24-Hour Consumer Experience: Employs advanced scent-anchoring technology to bond aromatic compounds to the hair fiber. This ensures long-lasting, continuous fragrance release that keeps hair subtly scented, fresh, and luxurious from morning to night.

Technology Features Ionic Core Delivery System: Uses proprietary ionic liquid technology to encapsulate hyper-concentrated Keratin and Silk PPTs, bypassing the hydrophobic cuticle barrier for direct cortex delivery. Precision Oxidation-Shield Dispenser: Custom air-tight pump protects high-density protein formulations from oxidation and environmental degradation, guaranteeing maximum formula stability, potency, and consistent dosage down to the last drop. Design Uniqueness & Aesthetics Architectural Spa Silhouette: Features a sleek, sculptural bottle design with a soft-touch matte finish and delicate color gradients, elevating everyday hair care into a luxury spa experience. Sustainable Components & Production Concentrated Water-Replacement Process: Replaces plain water bases with active Keratin, drastically increasing formula density and reducing freshwater footprint during manufacturing. Clean & Biodegradable Chemistry: Free from sulfates, parabens, and microplastics; utilizes 100% readily biodegradable amino acid surfactants to ensure aquatic safety and eco-conscious performance. 100% Recyclable PCR Resin: Constructed from post-consumer recycled (PCR) PET, significantly reducing virgin plastic consumption while delivering a premium, weighted tactile feel.
