Developer and Pigment Formulator: 10V to 40V Chemistry
Select starting level, target level, cuticle porosity, non-pigmented gray ratio, and disulfide bond buffering to compute optimal peroxide concentration, underlying warmth exposure, and neutralizing base tone.
Interactive Level, Porosity & Peroxide Bench
Instant Local CalculationThree-level lift requires high-alkaline swelling; monitor elasticity every 10 minutes.
Developer volume measures oxygen release potential rather than dye brightness: 10 Vol (3% H2O2) deposits pigment or lifts 0 to 1 level, 20 Vol (6%) lifts 1 to 2 levels and opens resistant gray cuticles, 30 Vol (9%) lifts 3 levels on healthy virgin shafts, and 40 Vol (12%) risks rapid cortex cysteic acid degradation if applied over compromised or previously lightened bands.
Level 1 to 10 Underlying Pigment & Counteracting Chromatic Chart
As alkaline oxidation dissolves dark eumelanin granules first, resilient pheomelanin molecules remain visible across predictable chromatic steps. Ignoring residual underlying pigment is the primary cause of brassy blondes and muddy brunettes.
| Target Level | Chromatic Description | Exposed Underlying Pigment | Neutralizing Counter-Tone | Typical Peroxide (Virgin) |
|---|---|---|---|---|
| Level 1 - 2 | Deepest / Natural Black | Dense Blue-Red | Neutral or Green-Ash | 10 Vol (3% H2O2) |
| Level 3 - 4 | Dark to Medium Brown | Dark Red to Pure Red | Green / Matte Base | 10 - 20 Vol |
| Level 5 | Light Brown | Red-Orange | Blue-Green Base | 20 Vol (6% H2O2) |
| Level 6 | Dark Blonde | Orange | Pure Blue Base | 20 Vol (6% H2O2) |
| Level 7 | Medium Blonde | Orange-Gold | Blue-Violet Base | 20 - 30 Vol |
| Level 8 | Light Blonde | Yellow-Orange | Violet-Blue Base | 30 Vol or Slow 20 Vol |
| Level 9 - 10 | Very Light to Pale Blonde | Yellow to Pale Yellow | Pure Violet / Pearl | Staged 20 Vol Persulfate |
Operational Limits & Failure Boundaries
Calculated outputs assume virgin or evenly documented shaft history. Overlapped permanent box color, metallic salt residues, or residual glyoxylic keratin coats alter oxygen diffusion kinetics and require a 15-minute strand test prior to full-head application. Review the full chemical spacing rules in the Bleach vs Keratin Matrix and cortical bond physics in Cuticle Chemistry.
