Joico LumiShine YouthLock NNWC Natural Natural Warm Copper (4NNWC–9NNWC) Permanent Crème Hair Colour (74ml / 2.5 oz) delivers 100% opaque coverage on stubborn, resistant grey hair while infusing rich, burnished warm copper radiance with age-defying softness and shine.
Primary Role: 100% Resistant Grey Coverage with Luminous Warm Copper
Formulating fashion copper on high-percentage, coarse white hair often produces hollow, hot roots or translucent ends. The YouthLock NNWC series eliminates guesswork by uniting a calibrated double-natural base (NN) with warm copper reflection (WC) in a single tube. It provides complete, opaque grey saturation while delivering vibrant, multidimensional copper depth without requiring a separate base intermix.
