OK, that came out wrong. You should never sell "yourself" for quick cash, but rather the parts of yourself that you can spare. Again, that doesn't sound right. What we're trying to say is you can sell blood plasma, sperm and even hair for cash. Wow, that was awkward.
College students have been flocking to plasma donation centers for decades to earn $35 for an hour and a half of magazine reading accompanied by a momentary needle prick [source: Bonander]. Donating plasma is perfectly safe for the average healthy young person and can be done up to twice a week. And the plasma itself -- the liquid portion of blood -- is used by doctors to save lives.
Sperm donation pays good money -- $50 to $200 per specimen -- but it's not exactly a "quick money" proposition [source: Bonander]. Sperm banks are very picky about their product and will need to run an extensive background check on your genetic health before taking you on as a donor. Once you get the green light, though, it's a pretty sweet deal.
Hair can also be a lucrative source of quick cash. To sell your hair for hundreds or even thousands of dollars, you will need a lot of it, preferably longer than 10 inches (25 centimeters). It should also be free of color or other chemical treatments and as healthy-looking as possible [source: Lu]. For a look at what sells, check out the live hair auctions on Online Hair Affair.
