Developer Chart Hair Colour Mixing Ratio
Formula for Developer Chart Hair Colour Mixing Ratio
The typical mixing ratio of hair color to developer is:
Color Amount × Developer Ratio = Developer Amount
Common developer ratios are:
- 1:1 (equal parts of color and developer)
 - 1:1.5 (e.g., 60 ml color × 1.5 = 90 ml developer)
 - 1:2 (double the developer compared to the color)
 
Formula:
Developer Amount = Color Amount × Developer Ratio

Hair color mixing needs correct proportions. The developer plays a key role. It lifts the hair cuticle and helps color deposit properly. In salons and home use, people must follow the correct developer ratio. Wrong measurements may damage hair or give bad results.

What is the Developer in Hair Colour?
The developer is a peroxide-based solution. It opens the hair cuticle and lets color go inside. It comes in different volumes: 10, 20, 30, or 40. Each volume has its purpose. For example:
- 10 Volume: deposits color only.
 - 20 Volume: lifts hair by 1–2 levels.
 - 30 Volume: lifts hair by 2–3 levels.
 - 40 Volume: lifts hair by 3–4 levels.
 
Hair stylists or users pick the volume depending on the goal. If the hair needs a light shade, higher volume is used. If the user only wants to change the tone, a lower volume is enough.
Why the Mixing Ratio Matters
The developer chart hair colour mixing ratio keeps the result even and safe. Hair color contains chemicals. The developer also has active ingredients. The right mix balances these. A common mistake is using more developers than needed. It can dilute the pigment. If less developer is used, the mixture becomes thick and cannot be processed properly.
The standard ratios are:
- 1:1 ratio — Equal parts of color and developer
 - 1:1.5 ratio — 1 part color + 1.5 parts developer
 - 1:2 ratio — 1 part color + 2 parts developer
 
These are used depending on the product and desired lift. Most permanent colors use 1:1 or 1:1.5. High-lift colors may need 1:2.
Developer Chart Hair Colour Mixing Ratio Table
| Hair Color Type | Developer Ratio | Purpose | 
|---|---|---|
| Permanent Color | 1:1 | Full grey coverage | 
| Permanent Color | 1:1.5 | Brighter and softer result | 
| High-Lift Color | 1:2 | For extra lift | 
| Semi-Permanent Color | 1:0 | No developer needed | 
This table helps users choose the right ratio.
How to Use the Ratio Formula
The basic formula is:
Developer Amount = Color Amount × Developer Ratio
Example:
If the color is 60 ml and the ratio is 1.5:
Developer = 60 × 1.5 = 90 ml
So, mix 60 ml of color with 90 ml of developer.
Common Developer Volumes and Their Use
10 Volume Developer
Use for tone-on-tone coloring or darkening. It does not lift natural pigment.
20 Volume Developer
Best for grey coverage and light lifting. It is widely used in regular coloring.
30 Volume Developer
Helps in lifting 2–3 levels. It suits darker hair, turning medium light shades.
40 Volume Developer
Used for high-lift blondes. It is stronger and may dry hair if used too often.
