Joico LumiShine organizes shades as level + reflect letters:
- Level (1-10): Color depth. 1 = black, 10 = lightest blonde.
- N = Natural
- NA = Natural Ash
- NG = Natural Gold
- NC = Natural Copper
- NR = Natural Red
LumiShine uses Argiplex technology (arginine complex) to strengthen hair during coloring. It is permanent color: lifts, deposits, and covers gray with exceptional shine.
Key feature: Most Joico fashion shades combine N + reflect letter (NA, NG, NC), indicating a natural base with added reflect. This gives balanced results without overly pronounced undertones.
