I just used the brass crap as well. I dyed my hair (like always) with the same feria golden blonde,and THIS time it turned totally red! WTF?!? I used the brass thing and now my hair is a crappy mouse brown!!!Its hideous! Now, I read above that I have to wait 4-6 weeks to re dye my hair???Did you do yours soon after? How did it turn out? I'm NOT going around like this!
