Which is better 20 or 30 volume creme developer when highlightening hair?

Answer 1

It depends on how light you want to lift the current color in your hair.

For light colored hair such as light brown to a normal dark brown you can use a 20.

But if your hair is a very dark brown that looks almost close to black you would use a 30 or maybe even a 40 if it's really dark.

A 20 developer will lift your hair color twice as much and a 30 developer,3 times as much.

Lifting means making it lighter.

You can watch the color as it processes and once it reaches the desired lightness you rinse to make it stop processing.

Most hair dressers start with a 20 volume developer but it still depends on the current color of your hair.
