1. Scientific Formulation: From Hair Structure to Precision Repair
1.1 Key Ingredients & Mechanisms
① High-Concentration Collagen Complex
- Penetration Test: Fluorescent labeling confirms that low-molecular-weight hydrolyzed collagen (<500Da) penetrates deep into hair cuticles, filling structural gaps.
- Repair Effect: Electron microscopy shows a 63% reduction in hair fiber porosity after 4 weeks of use (data from third-party SEM analysis).
② Ceramide + Phytosphingosine
- Barrier Repair: In vitro hair fiber tests show this combination increases cuticle smoothness by 82%, reducing friction damage (untreated hair cuticle angle: 45° → treated: 8°).
- Moisture Lock: TEWL (Transepidermal Water Loss) measurements show 57% less moisture evaporation from treated hair.
③ Natural Botanical Oil Blend
- Argan Oil + Camellia Oil: GC-MS analysis determined the optimal 3:1 ratio, improving hair elasticity modulus by 48%.
1.2 Formula Architecture: Balancing Stability & Efficacy
- Emulsion Optimization: A HLB 10.5 emulsifier blend (Polyglyceryl-3 Diisostearate + Cetearyl Alcohol) ensures no separation after 30 days at 45°C.
- Active Protection: Collagen is encapsulated in phospholipid bilayers, with HPLC confirming >95% retention after 6 months at room temperature.

2. Lab Validation: Data-Backed Performance
2.1 In-Lab Testing
| Test | Method | Result |
| Cuticle Smoothness | Scanning Electron Microscopy | 76% improvement after 1 use |
| Break Resistance | Tensile Tester (50mm/min) | 41% stronger wet hair |
| Shine Enhancement | Spectrophotometer (60° angle) | 35% higher reflectivity |
| Heat Protection | 230°C flat iron simulation | 68% less protein loss |
2.2 Clinical Efficacy Study
- Participants: 120 women (18-55) with varying damage (coloring, dryness, split ends).
- Usage: 2x/week for 4 weeks.
- Results:
- 89% reduction in split ends
- 72% easier combing (measured via tension meter)
- 96% reported "visibly softer, smoother hair"

3. Production: Precision from Lab to Mass Production
3.1 Manufacturing Challenges & Solutions
- Viscosity Control:
- Small batch: 12,000 mPa·s
- Mass production: Adjusted homogenization speed (2500rpm→1800rpm) and mixing time (5min→8min), ensuring <5% batch variance.
- Active Stability:
- Nitrogen-flushed filling prevents collagen oxidation (HPLC shows <3% degradation).
3.2 Quality Standards
| Test | CHENZHIMEI Standard | Global Benchmark |
| Microbial Limits | ≤100 CFU/g | ISO 17516 |
| Heavy Metals (Pb, As) | ≤1ppm | EU Cosmetics Regulation |
| pH Value | 4.5-5.5 (scalp-friendly) | Korea KFDA Standard |
