Igora Royal uses the level-reflect dash format: 7-1 = level 7 (medium blonde), ash reflect.
- Level (1-10, plus 12 in highlifts): color depth.
- Reflect: -0 natural, -1 cendré, -2 ash, -3 matte, -4 beige, -5 gold, -6 chocolate, -7 copper, -8 red, -9 violet.
- Double digits = intensified reflect: -11 extra ash, -88 extra red.
Watch out for the Schwarzkopf traps: Igora's -5 is gold (in Wella or L'Oréal, 5 is mahogany) and -7 is copper (in L'Oréal, 7 is matte; in Wella, brown — there is no shared key across brands). If you come from another brand, double-check the reflect before formulating.
Igora Royal developer: 3% (10 vol) tone-on-tone, 6% (20 vol) 1-2 levels and gray, 9% (30 vol) 2-3 levels, 12% (40 vol) maximum lift.
