If not shaving your head after a few days is bothering you.....I would just go ahead and shave it.....if your buddy really wants to shave his head he will do it regardless of whether you don't shave yours for 30 days or not.....your own sense of well being is more important and who's to say he won't chicken out after 30 days anyway....
Bleh,couldn't take it anymore.Shaved in shower 10 minutes ago,and I feel damn good! And for friend...heck,if he really wants to shave that dead proteins atop of his head,he will do it no matter if I have them shaved or no.5 days without shaving has been too much for me,here are results ;Day 1.Dear diary! Nobody understands me.I'm highly motivated.Day 2.Dear diary! I hate when I have 1mm hair.Full head of hair,or no hair at all.Day 3.Dear diary! This is getting sick,can't take it any more,I can't put up a T-Shirt on me!Day 4.Dear diary! Everybody hates me!This is horror.I think suicide is my only solution.Day 5.Dear diary,I have shaved it all and I'm feeling damn good about it,and there is nothing you can do about it.*Throws diary in fire*
