Oh my, I wouldn't dare to dye my hair, I've not even been to a hairdresser since I was 8 years old and my grandma sold my hair for a wig like in Little Women. I only tried to actually darken my hair from blonde to prerraphaelite red when I was a teenager and oh my it was a temporary one but still got blisters and have not messed since, I'm actually growing blonde to white grey all mixed at the moment. But I always long for the unicorn mermaid colours :) I use chalk and pastels sometimes as my hair is light, it lasts until next washbut it's not as pretty as that result
