Rockabilly Blue
I have always used Blue Moon on my daughters hair but had to switch to another blue since you don’t carry Blue Moon anymore. We tried Rockabilly Blue instead and it washed out so quick! Especially on the freshly bleached roots. We have had 3 separate applications wash out quick. That never happened with Blue Moon. We switched to Artic Fox until we can figure out which MP blue will work for her. We have been using MP and AF forever and use cold water and color safe products.
