Joico LumiShine YouthLock NN (Natural Natural) Permanent Crème Hair Colour (74ml / 2.5oz) is engineered specifically for salons and colourists addressing stubborn, coarse, and completely resistant silver and grey hair. While standard permanent colour often requires manually intermixing an additional natural base tube to prevent translucent, hollow coverage, the YouthLock NN series features a calibrated double-load natural pigment background that achieves 100% opaque, dimensional coverage straight from the tube.
Anti-Aging Restorative Hair Technology
Mature, silvering hair loses internal lipids, tensile elasticity, and natural moisture over time, resulting in a coarse, wire-like cuticle that resists colour absorption. LumiShine YouthLock addresses both structural aging and pigmentation:
-
Hydrolyzed Collagen: Re-infuses depleted hair fibers with essential structural proteins, restoring youthful suppleness, body, and tactile softness.
-
Buriti Fruit Oil: A nutrient-dense botanical lipid that replenishes lipid moisture, smoothing the raised cuticle layer for silky combability and comb-breakage resistance.
-
ArgiPlex Bond-Building Technology: Formulated with bio-identical Arginine and fermented green tea seed extract, rebuilding broken internal bonds and locking in up to 2X radiant shine compared to untreated damaged hair.
-
Gentle Fresh-Fragrance Formula: Proprietary odor-neutralizing technology that captures and encapsulates ammonia fumes for an elevated salon experience.

Professional Mixing, Formulation & Processing
For consistent, predictable grey saturation, strictly adhere to Joico manufacturer specifications:
-
Mixing Ratio: 1:1 (equal parts YouthLock NN crème colour to dedicated developer).
-
Developer Selection: Mix exclusively with Joico LumiShine Crème Developer 20 Volume (6%) as the gold-standard benchmark for 100% resistant grey coverage. Use 30 Volume (9%) only when 2–3 levels of natural lift are required alongside grey blending. Never mix with 5 Volume or 10 Volume for resistant grey applications, as they lack the oxidation energy required for cuticle penetration.
-
Processing Time: Process for 35 to 45 minutes at room temperature. For ultra-coarse, glassy, or 100% white hair, process for the full 45 minutes. Do not use heat lamps or processing caps, as accelerated heat compromises tone calibration.
-
Intermixing: Fully compatible with YouthLock NNA (Cool Ash) to cool warmth, or YouthLock NNWC (Warm Copper) for rich autumn reflects. Reference the Joico YouthLock Colour Chart for tonal cross-matching.
