Key ideas in Formulating with Matrix Hair Color
- Matrix levels run on a 1 (darkest black) to 11 (lightest blonde) numerical scale
- Letters indicate the tonal reflect such as Warm, Ash, or Red
- Numbers and letters combine on the tube (e.g., 6VR) to define the full shade
- The first letter after the number contributes approximately 70% of the visible reflect
- The second letter provides a softer 30% nuance or secondary reflection
- 7BC will show up primarily brown with a soft secondary hint of copper
- Matrix Pre-Bonded contains citric acid and taurine already built into the color cream
- Formulas mix cleanly with standard developer ratios without altering volume
- No separate bond-builder additives (like standalone Olaplex) are required
- Assessing the natural level (1-11) determines how many levels of lift or deposit are needed
- Grey percentage dictates whether extra natural/warm background is required for complete coverage
- Porosity determines how fast and deep the color will grab
- Lightening natural hair exposes warm underlying pigment (red, orange, or yellow)
- Matrix shades combine background color with tonal reflect, so exposed warm undertones add into the final result
- To get a cool target result, the artificial reflect must counteract or neutralize the exposed natural warmth
- Matrix SoColor permanent contains ammonia to swell the cuticle and lift natural melanin in the cortex
