Hi Shay,
I use to be an endocrinology nurse. First of all Tubal Ligation's do not alter your hormones. Your sexual hormones are transferred from you ovaries into you blood stream. If that were the case then women with one patent tube couldn't become pregnant. My guess your hair loss is stemmed from different factors. Anemia, Hypothyroidism, Estrogen Dominance and stress are the main biggest factors for hair loss. They are also very common in women. Most doctors are not educated enough in these areas to assist women with these problems. Look up www.drjohnlee.com/ and see if any of these symptoms fit you. If they do then you need to possibly seek the assistance of an endocrine specialists who will guide you in the right direction.
Also. I was suffering from severe hair loss after my daughters were born. Nobody could give me any answers. I later had a saliva test performed to tell me that my cortisol levels were off the chart and my progesterone levels were way lower than my progesterone. I had estrogen dominance. Which was induced by stress. Which hair loss is a big symptom. Something I had to research myself because your average family doctor or Gyne isn't versed on. So I know your pain. There are several Natural remedies that are safe that treats stress, and hormonal disorders.
I hope you find and answer for what your looking for.
