Not to stereotype, but there is certainly a link between increased hair loss and ethnicity. This can probably be linked to diet to some degree. The Asians in "western" countries might be a little more prone to baldness, and this would only further show that diet has something to do with hair loss. Most Asians eat high soy and protein diets centered around pasta, rice, and seafood. When Asians come to the US and other "western" countries, their diets tend to change a little. The overall point that should be taken, is that we should attempt to eat more healthy high protein diets. At the very least it will help keep you in good shape, and it might help with your hair loss. I have recently added soy protein powder to my diet, along with a multi vitamin. I have also cut back on the fast food(maybe once a week at most). Not sure that it has any effects on my hairloss, but my body feels like it is in the best shape every(increased confidence), so it is certainly worth trying.
