Shaving head not only saves money for ya but also time in a long run, plus you get more skin to sun exposure = more natural vitaminD be it winter or summer

plus for starters just out of curiosity count and add up minutes it takes you to shower your hair then dry them then groom them and then troughout entire day worry about them if they look sufficiently ok or if they got messedup because you hit your scalp getting in to the car etc... I find it to be waste of time, I value my time more than others opinions of my hair, I shave once or twice a month, and unless caffeine shampoo works like magic, I will go shaving weekly soon since I can see thining of the hair and balding pattern already, otherwise I may trim really short #2 etc and just once montly. It depends how your hair makes you or your loved ones feel too I guess, the owner of the hair gets to decide.
