I think these are all her hairstyles, if there aren’t all, at least most of them are. We didn’t put pictures of when her hair was fading neither when it was white again between her hair “colorful hair colors”. I tried to put them in a timeline, but it isn’t 100% right. If you wanna a perfect timeline, go through her blog and/or her twitpic.
edit: we’ve just added the last two pictures of her short hair.
