Majirel uses L'Oréal's dot notation: 6.3 = level 6 (dark blonde), golden reflect.
- Level (1-10): depth, from black to lightest blonde.
- Reflect: .1 ash, .2 iridescent, .3 gold, .4 copper, .5 mahogany, .6 red, .7 matte, .8 mocha.
- Double reflect: the first digit rules — 8.34 is gold with a copper nuance.
Majirel is the usual reference when translating shades between brands, but its key is not a universal standard: Wella and Igora print their own. The family variants (Majirel Cool Cover for cool bases, Majirouge for intense reds, High Lift for maximum lightening) follow the same numbering logic.
