This post comes from Dr. Richard Shiell:
Dr Masumi Inaba, who wrote a book on Androgenetic Alopecia (Springer 1996), was firmly convinced that the increase in Western style animal fats was causing an increase in baldness in young Japanese males. I am not sure that his statistical method would stand rigid scrutiny however.
The same lack of good statistics applies to all the popularly believed “causes” of baldness. Forty years ago when I was a young HT surgeon, the patients all blamed the wearing of hats in the Army or Police Force as the cause of their baldness, when I am sure that it was just that they entered these institutions at the precise age that severe AGA usually kicks in (19-21 years old).
I certainly believed throughout my career that “gym-jocks” lost hair more quickly than their “lay-about” brothers and cousins. The problem is that many were taking steroids and other “dietary supplements” so it was a very confusing issue to ascertain causality.
I had one of a pair of 25 year old “identical” twins who had lost significantly more hair than the other. When I spoke to the more hirsute twin about it he laughed and said it was because his brother was married with a child and mortgage, and had more stress. So there you have undeniable evidence from a large series of ONE case!!
Hair loss is the results of many complex things. For example, dietary supplements like whey and a variety of branched amino acids including creatine, push up men’s testosterone levels (and their DHT levels), which in turn accelerate hair loss. We are what we eat, I just wish I understood all of the complexities of diet as it impacts the hair loss we see.
