Joico LumiShine YouthLock NNA (Natural Natural Ash) is a salon-exclusive permanent crème hair colour engineered specifically for clients with coarse, stubborn, and resistant silver or grey hair who require 100% opaque coverage while combating unwanted warmth. Formulated with a calibrated double-natural background infused with cool ash reflect, the NNA series effectively neutralizes underlying red, copper, and brassy undertones in a single, predictable formulation without requiring a separate base tube.
Anti-Aging Restorative Hair Technology
Aging grey hair typically loses internal moisture, elasticity, and outer lipid protection, leaving cuticles wiry and dry. YouthLock counters aging hair texture through three active restorative complexes:
-
Hydrolyzed Collagen: Re-infuses moisture, tensile strength, and noticeable body, returning youthful suppleness and combability to coarse strands.
-
Buriti Fruit Oil: Packed with essential fatty acids and antioxidants, providing deep nourishment, hydration, and luminous surface polish.
-
Bond-Building ArgiPlex™ Technology: Harnesses bio-identical Arginine to replace essential amino acids stripped during chemical services, locking in colour longevity and delivering up to 2X radiant shine.

Professional Mixing & Processing Guidelines
-
Mixing Ratio: Mix 1:1 (equal parts YouthLock colour and dedicated Joico LumiShine Crème Developer).
-
Developer Selection: 20 Volume (6%) is the mandatory standard for 100% resistant grey coverage. Use 30 Volume (9%) only when 2 to 3 levels of natural lift are required on unpigmented regrowth.
-
Processing Time: Process for 35 to 45 minutes at room temperature. For very resistant, coarse, or wiry grey hair, allow the full 45 minutes. Do not use heat lamps or processing caps.
