Could the obesity be contributing to the baldness? Has anyone noticed that some obese people tend to have lots of wiry body hair in places other than the chest such as the back, shoulders, and arms. And overweight women tend to grow lots of facial hair.. perhaps the same hormones increasing body hair increases the risk of baldness??? Just a thought..
It is a good thought, but it is not completely correct. Genetic factors cause hair loss. Hair loss is not related to obesity or vice versa. However, I believe there are genetic factors that contribute to obesity (unrelated to hair loss).
Overweight women who have facial hair reflect a term called hirsutism, which you can learn more about here. It is related to hormonal imbalance and an increased amount of androgens in the blood stream.
