If you look at David outside under bright light, you can see his hair is now green. Otherwise, you can't tell. David is extremely disappointed the kool-aid hair dying experience did not succeed. We followed the internet directions. Almost. It's just that we just used only one packet of kool-aid instead of three. And when it rinsed out, it really rinsed out. That was a hard morning with David crying and yelling at me, but tonight when he said he didn't want to wash his hair, so the green wouldn't go away, I said ok. I seem to be forgiven.
