We’ve created this hair dye ratio calculator helps compute the precise amounts of different hair dye components needed to achieve the desired color result.
- 1:2.5 Ratio: Commonly used for lightening hair with a more diluted developer.
- 1:4 Ratio: Often used for very gentle processing, suitable for pastel colors.
- 1.5:1 Ratio: Provides a richer color with more pigment, often used for deeper shades.
- 2:2 Ratio: Balances color and developer equally, often used in creative coloring.
- 3:1 Ratio: A high pigment ratio that can create bold, vibrant colors.
- 1:1.2 Ratio: Slightly more developer than color, giving a softer result.
- 2:3 Ratio: Used for specific techniques like balayage where a lighter touch is needed.
- 1:6 Ratio: Ideal for very subtle highlights or toning, providing a sheer finish.
- 3:2 Ratio: A balanced approach that allows for both vibrancy and depth in the color.
- 4:1 Ratio: Used for deep conditioning treatments mixed with color.

Hair Color Mix Formula
The Hair Color Mix Formula is the backbone of successful hair coloring. It typically involves combining three main components:
- Color cream: The pigment that gives your hair its new hue
- Developer: An oxidizing agent that helps open the hair cuticle and deposit color
- Additives: Optional components like toners or treatments
The general formula is:
Total mixture = Color cream + Developer + AdditivesDifferent brands and color types require varying ratios.
- Permanent color often uses a 1:1 or 1:1.5 ratio
- Semi-permanent color might use a 1:2 ratio
- Highlighting formulas could require a 1:3 ratio
For a permanent color with a 1:1 ratio, if you’re using 60ml of color cream, you’d mix it with 60ml of developer.
How to calculate hair dye ratio?
Here’s a step-by-step guide:
Identify the required ratio from the product instructions
Determine the total amount of mixture needed based on hair length and thickness
Divide the total amount by the sum of the ratio parts
Multiply the result by each part of the ratio
Let’s say you need 90ml total mixture for a dye with a 1:2 ratio.
- Total parts: 1 + 2 = 3
- Amount per part: 90ml ÷ 3 = 30ml
- Color amount: 30ml × 1 = 30ml
- Developer amount: 30ml × 2 = 60ml
You’d mix 30ml of color with 60ml of developer.
What does 1 part to 2 parts mean in hair color?
The expression “1 part to 2 parts” in hair coloring refers to the proportion of different components in the mixture.
In this case, it means you need twice as much of one component compared to the other.
For a 1:2 ratio with a total mixture of 60ml:
- 1 part (color): 20ml
- 2 parts (developer): 40ml
This ratio is common for:
- Semi-permanent colors
- Some highlighting techniques
- Certain toning formulas
What is 1 to 1.5 ratio hair color chart?
A 1 to 1.5 ratio hair color chart is a guide for mixing hair dye where you use one part color to one and a half parts developer.
This ratio is frequently used for:
- Permanent hair colors
- Full gray coverage
- Achieving more vibrant or intense shades
For 100ml of total mixture:
- Color: 40ml
- Developer: 60ml
How much is 1:1 ratio for hair dye?
The 1:1 ratio for hair dye means equal parts of color and developer are mixed. This is one of the most common ratios used in hair coloring, especially for:
- Permanent hair colors
- Root touch-ups
- Some semi-permanent formulas
If you need 80ml of total mixture:
Color: 40ml
Developer: 40ml
