Earlier this week, Kelly Brooke was spotted leaving her London house with noticeably visible roots. While I knew that Kelly dyes her long golden brown hair, I had no idea that she was actually so intensely dark naturally.

Back when I was a blonde, I'd have to head to the salon for touch-ups at least every four to six weeks. Then when I got highlights, I'd go every two to three months.

However, now that I'm completely dark, all I really do is have a toner applied whenever I fancy a pigment pick-me-up. How often do you dye your hair?
