two incidents come to mind - 1. cutting my bangs in the middle of the night and the phone rang as I was snipping. I made a big diagonal cut right in the center of my bangs.
2. tried to dye my entire head a bronze color using only one box of dye. My hair is very thick and hangs well past my shoulders. The back was postitnote yellow, the middle was red the front was a mix of yellow red and brown. My son looked at my and literally cried. I used a henna dye to darken it up some but it was horrible and took YEARS to finally get all of my hair back to one shade.
