Most of the stuff I've put in my hair wouldn't be considered crazy by this boards standards.

I when I was 12, I had to do this testing that involved putting electrodes on my head, and they kept them on with plaster of paris. The dr told me it would easily wash out with shampoo, but it didn't and it was during the school year. I used just about everything I could think of to get it out, dish soap, I think I might have even given laundry soap a try but I don't remember a whole lot except the difficulty, and the embarrassment of going to school with while flaky blobs on my head.
