Ivette:
The "high-volume" loss may have been temporary, due to the onset of your thyroiditis. If your dermatologist diagnosed pattern hair loss, he must have thought that you are losing your hair on an ongoing basis, over and above the thyroid issue.
Alsdomet is ususlly given for high blood
pressurePressure ulcer. If you mean
Aldactone, this is sometimes prescribed for pattern hair loss (and other things), and is safe and worth perhaps at least a try. As for viviscal, I have never heard of it. I'm doubtful that it will be of help.
Another option you might want to consider and discuss with your dermatologist is minoxidil, now over-the-counter, safe, and much less expensive than it used to be.
Keep in mind that female-pattern baldness is much slower and less severe than male hair loss. It may well be amny years before your hair is thin enough for anyone else to notice.
Best.
