Step 3: Restore hair color
Dissolve 6-8 aspirin pills in water, then rub the solution into your hair. Let it sit for 10 minutes and rinse it out. The greenish effect should start to disappear after a couple of aspirin washes.
When I was in fifth grade, there was a girl in my class with hair so blonde and fine it looked like fiberoptic wire. She was a swimming fiend, so her hair was always just a touch too green in the summertime. In middle school, she acheived the Edenic self-consciousness of Eve and began to use aspirin to fix the greenness. She is now incredibly successful and one of 17* female engineers in the whole world. Aspirin helped her become a foxy materials engineer, imagine what it could do for you.
*I know that there are more. But there are still too many girls being discouraged from careers in science and math. The real number is probably in the low to mid 50s.
