Phase 1: Formulation & Ingredient Audit

Before a product touches hair, we analyze its International Nomenclature of Cosmetic Ingredients (INCI) list. We look at active surfactant concentrations, silicone types (water-soluble vs evaporative vs heavy dimethicones), hydrolyzed proteins, humectants, and pH balance.

Phase 2: Multi-Texture Panel Trials

A formula that excels on fine, low-porosity 1A hair will behave completely differently on coarse, high-porosity 4C coils. We test across our panel of testers representing:

  • Straight & Fine: Testing for weight, grease buildup, root volume, and thermal defense.
  • Wavy & Normal: Testing for frizz reduction, bounce, and wash-day longevity.
  • Curly & Coily: Testing for moisture retention, clump definition, shrinkage control, and slip during detangling.
  • Color-Treated & Bleached: Testing for bond repair, porosity sealing, and color vibrancy retention.

Phase 3: Longevity & Wear Performance

First impressions can be misleading. We evaluate products over a 2-to-4 week cycle to observe long-term buildup, moisture equilibrium, and scalp response under changing humidity and seasonal conditions.

Phase 4: Cost-to-Value Assessment

Is that $48 luxury hair oil genuinely better than a $14 cold-pressed argan alternative? We compare performance against accessible drugstore benchmarks to ensure our recommendations respect your beauty budget.
