In regards to this topic, I do believe our diet plays a part in it. I for one am guilty for having some bad eating habits through childhood and into adult life but I also believe that it is in our genes. If we are susceptible to baldness of any kind in our dna I think we are SOL no matter what. That being said if we choose to lead an unhealthy lifestyle I think we speed up the aging process which in turn speeds up the hair loss process. Dr. Oz from Oprah's show, stated there are people out in the world who are a certain age in years but biologically they are older because of poor lifestyle choices whether eating habits or lack of physical activity or smoking or drinking, etc...I believe this to be true, I am trying to change my ways but once something becomes habitual it's hard to do a complete 360 and say ok I am now this and break those habits. One need only look at the numerous athletes who lead healthy lifestyles, they all seem to have every hair in tact, look at hockey players. And then there are actors who are in their mid 30's and don't look a day over 25 take a look at guys like Jared Leto, Corey Feldman, Vida Guerra, Alison Lohman, I'm sure you can spot a pile of others. I wonder if living a vegan lifestyle is the true fountain of youth, I mean how else can people in their mid 30's, early 40's continue to look like they are in their 20's? It's unreal and it feels like I missed the boat on information that would have been extremely beneficial to me and my life.
