** this post has no scientific backing ** I've never quit smoking, so I can't say for sure and can only go by observation. Recent events in my life over the past year have caused me to smoke more, i was about 6 a day and now I'm 12. Oddly enough, my hair hasn't looked this good in 6 years (obviously because i started doing somethign about the loss. not because i started smoking more.) How many smokers do you know with thick *** heads of hair?? If youre genetically programmed to go bald, I doubt quitting smoking will save you. It might be an all around good idea to quit though.
