orange hair

well, i was a bit stupid the other week and i decided to try and bleach my hair, even though i had been dying it for 3 years, i still wanted to try and get from jet black to blonde so i would be able to put a cosmic blue on top, however it went horribly wrong and i ended up with really blonde roots and orange hair, i came on here to see if anyone else had the same problem and was amazed at how many people did the same thing as me, i did get it fixed and i now have my black hair back, but i had to go to the hairdressers and have a red put in and then a black on top, anyone reading this who is thinking about dying their hair blue black over a normal black then it does work when you just put the new colour on top of the old one
