Does obesity cause hair loss?

Maybe but ask doctor: A person with obesity and hair loss may have a hormonal problem that a doctor can evaluate. Men with obesity may have higher levels of Estrogens (female-type hormones) due to estrogen produced in fat cells, which could lead to a smaller amount of "masculine-type" body hair. On the other hand, a person could be obese and losing hair, without the two symptoms having any relationship to one another.
