I am a long-time admirer of men with long hair, but sometimes they do cut it off for a number of reasons. If you do find you're going to be Delilah-cized, please consider doing what Sammy Hagar did on the Tonight show and donate the hair to a very worthy cause which uses donated hair to make hairpieces for children suffering hair loss from medical treatments and conditions:

I personally am not affiliated with this organization or with Sammy Hagar, but have seen effect that this act of generosity can have on both the giver and recipient.
