I started out gradually, and got blonder and blonder as time went on.
I should point out that I was bleaching my own hair each time. And I didn't just bleach the roots, like you're supposed to. I did all of my hair...every single time. I really don't know what I was thinking. (Actually, I'm pretty sure I was thinking super blonde hair = hot.) I finally stopped bleaching it when I noticed several chunks of my hair were way shorter than the rest of it. So basically, my hair was breaking off. My poor locks!
So, I decided I'd dye it back to plain ol' brown. By myself. Without using a toner. If you are like I was and don't have any knowledge of hair color, than you might not guess that this would turn my hair bluish-gray. Because I sure didn't guess that's what would happen. But it did. I really wish I would have taken a picture of that, but I rushed to the salon the next morning to have it fixed.
Since then I've had brown hair, with the occasional highlights. By a professional only! And my hair has thanked me for it.
Got any embarrassing hair stories of your own?
