Does Propecia really work??

Inside the head of Ben Dodds on a cold, Saturday afternoon:
Periodically I will go back through old photos from my past and reminisce about the good 'ole days. I have to admit, every once in a great while I wish I had more hair. Why do I waste my time wishing for more hair?? Is it a vanity thing? Am I that caught up in the "fashion trend" scene? Back in the day I actually had hair and in college, I had a lot of hair! Now, I shave my head due to the lack of growth. What is a man to do? I do think it is kind of funny when men my age try to solve/fix their lack of hair growth. Why do men care about their hair? We are talking about guys that wear the same boxers 2 to 3 days in a row, pick there nose while driving in the car, pass gas under the bed sheets (sorry but it had to be said), eat greasy hamburgers 3x a week for lunch...etc. And these guys are actually worried about what they look like up top. These same men will spend $3 dollars a day to take a pill that is suppose to stimulate the hair follicles and help provide minimal hair growth. Isn't it funny! I'm not saying I haven't been one of those guys in the past but I have some many other things to focus my time on. So...I say no to the little pills and yes to the clippers. What do you think?? Do you like the hair??
