I used the Electric Blue hair dye - two packs, and it worked well! Very simple to do, you just put it on your hair, wait half an hour, and wash it out!
In my opinion, it lasts about 2-3 weeks. In the video, it doesn’t look that blue but that’s because I had very red hair before I used it. I have also used this color before this time, when it turned properly blue.
It left my hair very soft and not damaged. Would definitely buy again!
