Question of the month!
Since I dyed my hair blue for about a month now, I received questions about:
"How did I maintain it?"
To be honest my hair is damaged from the colouring, straightening & curling.
Therefore I'm not proud about my hair but to answer your questions,
I re-dye my hair every two-five day or else it will turn green then blonde.
It's not easy nor cheap but I love it.
