Because graduate students have nothing better to do than change hair colors, and because I had a bag of henna I'd been given and never used, two nights ago I dyed my hair for the first time. It started out dark brown, so I didn't worry too much that it would turn out carroty:
(before: the back of my head, weird angle)
I basically followed the instructions on this website, except it turns out I didn't quite have enough henna to glop it on as thickly as you're supposed to. Even so, it felt like I was giving myself a delicious mudbath. Scratch that, I did give myself a delicious mudbath. Deliciously stinky - kind of a combination of clay with lemon, producing a smell not unlike dried fruit. I proceeded to wrap my head in Saran Wrap and walk around the apartment with a Saran beehive for three hours. (No photo of that, unfortunately! But it kind of looks like this.) I felt very Jetsons-take-on-50's-housewife. And now I have auburn highlights!
(photo goes poof)
(after, looking more washed out yet sultry than normal)
This might become a monthly tradition, although I think it would benefit from being a multi-person activity -- it was hard to get to the back, and it's just plain fun to glop mud on someone else's head.
