About 6 years ago I wanted to get blonde undernearth my naturally brown hair (don't know why, it must have been cool at the time ha) and the hairdresser agreed, thought it would look great, should be easy etc. Instead of blonde it went orange, not just ginger, full blown bright fluro orange. And it wasn't undearneath, it was in big blocks. Looked so horrible. I paid a fortune for it too.
