Hi
Has anyone used 3% peroxide to cover grey roots with Wunderbar Base 9? If so did it cover well? I used 6% last time & it didn't cover 100%
I'm new to this brand as I used to use Rusk but they've been discontinued![Confounded face :confounded: š](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f616.png)
