I would strongly advise against it OP, it's a very slippery slope; the pills are the same ones they give to transexuals - they are hormone blockers that effectively stop uptake of a male hormone, they stop you being a man. Long term they will stop your penis working, and your future wife will not be impressed if you can't even get it up for her, all because you wanted to keep some lank hair that turns grey anyway.
God has made you perfectly, embrace what He has created. Keep it short or shave it, but focus more on what you can control, i.e. getting bigger and keeping fit and healthy.
