When a star radically changes their hair color or length, it's almost always a career-killer. Once they've made their first big splash, that's how most people will remember them. It's such a stupid mistake, yet so many keep making it every few years like clockwork. When the failure rate on such things is sky high, folks, don't go ahead and do it anyway, just because you can. Or you'll end up like everyone else back at the bottom, with that ugly red henna crap in your hair, and renting yourself out for cheap.
