I agree that the thyroid can be an influence on hair growth, but my doctor has been testing me for thyroid imbalances for some time without results.

There is some heredity in this also. By teh age of 19, I had thinned in a triangular shaped on the top of the head and I know it was an inherited trait from my Dad's side of the family but it only affects the women.

Tis being said, stress has also affected hair loss occasionally, but when the stress was taken care of, the hair returned. This latest hair loss of mine could be due to peri-menopause. I am in the throws of hot flashes lol. This morning, I felt like hot stuff. I can't get a doctor now until January due to the fact that I have moved. My new health care won't kick into effect until January so I have to wait to see a doctor about it. I geuss I just have to wait it out until then.
