Help with Igora Vibrance

[helzbelzwelz]

Hi, I am hoping to use vibrance for the first time as a lowlight on my client, but using a bleach highlight too. Can anyone tell me if you leave it on longer than 20 mins, the colour darkens? As I know the matrix tone on time do.

In my experience, I found vibrance not to be progressive. It just levels off where it is, and stops working after 20 minutes. If you put it under heat, it can go a bit darker and more intense then usual though.

Thank you.
