Get the exact hair color and developer formula for every client, in seconds. Across every brand, ratio, and service.
Most calculators ask for a total amount and a ratio. We start with the actual hair, then work backwards to a formula you can trust.
Length, density, gray coverage percentage, and the service you're doing, from full color to root touch-up, balayage, highlights, toner, or color correction. Real factors that change how much hair color and developer you actually need.
Wella Koleston Perfect, Wella Color Touch, L'Oreal Majirel, L'Oreal INOA, Schwarzkopf Igora Royal, Redken Shades EQ, Matrix SoColor, Pravana ChromaSilk, Pulp Riot, Goldwell, Paul Mitchell and more. We pre-fill the correct mixing ratio (1:1, 1:1.5, or 1:2) so you don't have to look it up.
Color, developer, and total mixture in oz, grams, or ml, with the right developer volume (10, 20, 30, or 40) for your goal. Save it to the client's profile in Goldie so the next visit takes seconds, not minutes.
Hair color levels run from 1 (deepest black) to 10 (lightest blonde) on the international level system. When you mix two levels in equal parts, the result lands roughly in the middle. This is the foundation of every formula, whether you're working with permanent color, demi-permanent, toner, or lightener.
A 6 mixed with an 8 in equal parts gives you a 7. Stay within 2 to 3 levels of difference for predictable results, and remember that natural underlying pigment shifts from red at level 1 through orange in the 5-6 range to yellow at 9-10.
A digital scale gives consistent mixes every time. Volume estimates from a tube are off by 10 to 15 percent on average.
Mixed color is only active for 30 to 60 minutes. Better to have a small surplus than to run out mid-application.
Different oxidation chemistries. Mixing them gives unpredictable lift, deposit, and processing time.
Adding developer above the ratio dilutes pigment and gives weaker, faster-fading color. Increase developer volume instead, not amount.
