I've grew my colour out a few times over the years. The only thing that annoyed me was how patchy it looked, it's white at the front and sides, getting darker towards the back. I'm naturally dark brown.
It looked a bit daft (imho) because I had a very short pixie cut.
I decided to try to grow my layers longer and went dark from bleached platinum.
The last couple of days I've been bleaching again because Ive decided to see how my colour grows out and would prefer not to have the skunk line.
Whether I stick to it is another matter
