Hashimoto’s Disease in Women

I am a woman, 40 years of age, and having a hair loss problem for over 18 years. I used to have very straight and thick hair, but now very thin and fluffy. I tried too many kind of shampoos, vitamins and programs. One of them, 101product, was no help. I have had an autoimmune disease called HASHIMOTO for 16 years. I’m taking medication and everything is under control. My doctor told me after he did all kinds of tests that i don’t have any physical problem causing my hair loss. My question is what do you think could help me? My sister has the same problem and she doesn’t suffer from anything physically.Your replying back will be appreciated.
Thank you

You may have both female genetic hair loss plus Hashimoto’s Thyroiditis and your sister may have the genetic element, which tends to run in the female line in particular families. The existence of Hashimoto’s Thyroiditis or any auto-immune disease can precipitate hair loss. Medications that treat these autoimmune problems often have hair loss as a side effect. Woman’s hair loss is extensively discussed here and I suggest that you and your sister read my many answers to questions which will contain many bits of insights for you here.
