In men, genes seemed to be the biggest predictor of balding, though smoikng, drinking, stress, and sun exposure also factored in. Although that may sound discouraging, experts say the research comes with a silver lining: Adopting healthier habits and controlling stress can sometimes help hair come back.

I've been smoking for two years and it hasn't affected my hair at all--or not in a way that is cosmetically significant. A buddy of mine is a huge drinker, smokes a pack a day, tokes everyday and has a better hairline than me.
