CIRS provides hair care efficacy and damage evaluation testing, using six key damage evaluation models – heat, chemical, physical, air pollution damage, UV, sea/pool water exposure – applied to 3D human hair tresses.
Physical Performance Evaluation of mechanical properties and visible hair performance. | Chemical Composition Quantitative analysis of key hair components and biochemical changes. | Microscopic & Structural Analysis Advanced imaging and structural characterization of hair fibers. |
Dry and wet combing performance | α- keratin content (DSC] | Cuticle repair and surface texture analysis |
Frictional properties | Lipid content (GC-MS & LC-MS/MS) | Cross-sectional structure analysis |
Tensile strength and fiber resilience | Amino acid profile (HPLC) | Hair fiber morphology comparison |
Gloss and shine assessment | Lipid peroxidation (UV analysis) | Protein penetration studies |
Surface hydrophilicity | Protein loss and dissolution (UV) | Spectroscopic characterization |
Hair breakage analysis (number of broken fibers) | Moisture content (TGA] | Hair integrity assessment |
Spilt end evaluation | Disulfide bond integrity (Raman Spectroscopy] | Core penetration analysis |
Anti-frizz and anti-static performance | Fragrance longevity evaluation | Dye penetration testing |
Curl retention testing |
| Hair porosity and void ratio evaluation |
Color durability assessment |
