What is 40 Volume Developer?
40 volume developer is a hydrogen peroxide solution that plays a crucial role in hair dyeing. It activates the color molecules in hair dye, allowing them to penetrate the hair shaft and deposit color. The "volume" refers to its concentration, with 40 volume developer being 12% hydrogen peroxide.
How Does 40 Volume Developer Work?

When to Use 40 Volume Developer:
While 40 volume developer is suitable for several situations, it's essential to consider the following factors:
- Hair condition: If your hair is already dry or damaged, 40 volume developer might cause further damage. It's always recommended to consult a professional stylist before using a strong developer.
- Desired color: If you're aiming for subtle changes or working with delicate blonde shades, 40 volume developer might be too strong. Lower volume developers like 10 or 20 volume might be better suited.
- Hair texture: If your hair is fine or porous, 40 volume developer could be too harsh, leading to over-processing and damage.
Cautions and Considerations:
- Always conduct a strand test: Before applying 40 volume developer to your entire head, test it on a small section of hair to check for any adverse reactions or unwanted color changes.

In conclusion, 40 volume developer is a potent tool in the hair dyeing process, suitable for achieving dramatic color changes and covering gray hair.
