Manic panic blue not working
I’ve been dyeing my hair blue for about 5 years. Recently i had to switch to manic panic because my previous hair dye was discontinued. When i last dyed my hair i used shocking blue and bad boy blue and it worked perfectly. This time i used shocking blue and rockabilly blue and the colour did not stick to my roots. For context i dye my hair professionaly and my roots were bleached to a level 10 as always. I had this happen before with a different color line where the problem was the dye itself. So this time im suspecting the fault was in the shade rockabilly blue since i used shocking blue last time and had no issues.
Has anybody had a similar experience with this shade? The colour looks fine elsewhere only my roots are lighter and it looks bad.
