How pros use 12/0

Used for major blonding without bleach
Ideal for lifting level 5–7 hair into blonde range
Creates a natural, clean blonde base (no strong ash or gold bias)
Often followed with a toner for refinement
Formulation basics
Mixing ratio: 1:2 with Welloxon developer (typical for Special Blondes)
Recommended developer:
30 Vol → controlled lift
40 Vol → maximum lift
Lift: Up to ~4–5 levels depending on starting level and hair type
Pro insight
12/0 is your “clean lift” blonde:
Gives maximum brightness without strong tonal push
Leaves a natural blonde canvas for toning (ash, beige, violet, etc.)
Will expose underlying warmth—toning is usually required after
Compared to:
10/0 → softer, less lift, more natural coverage
12/1 / 12/81 → added ash or pearl to control warmth
