Hashimotos Hairloss

Hi, I have hashimotos and I am currently slightly over replaced on levothyroxine. I have low calcium and am waiting on vitamin D results. 4 months ago I was undermedicated. For more than 6 months now I have been steadily losing hair and today I noticed a slight bald spot. Has this happened to anyone else and do you have any advice as to how I can reverse this hair loss? Thanks

What do you mean by over medicated? TSH suppressed? FT4 and/or FT3 over range? My hair started coming out in clumps when FT3 was over range. I reduced dose to allow FT3 to drop and hair loss stopped about 7 weeks later.


Do you have your latest blood test results, ideally TSH and including FT4 & FT3, TT4

If they have not been done ......Suggest you ask GP to check levels of vitamin d, b12, folate and ferritin. These all need to at good (not just average) levels for thyroid hormones (our own or replacement ones) to work in our cells. Very common to be low in some or all of these especially with Hashimoto's

ALWAYS Make sure you get the actual figures from tests (including ranges - figures in brackets). You are entitled to copies of your own results.

If you can not get GP to do these tests, then like many of us, you can get them done privately

Special offer at moment

As you have Hashimoto's then you may find adopting 100% gluten free diet can really help reduce symptoms, and may lower antibodies slowly over time too. Some with Hashimoto's also (or instead) find other foods may need avoiding, dairy, soya and nightshades (tomatoes, peppers, potatoes) being the common ones. You do not need to have ANY obvious gut issues, to still have poor nutrient absorption or low stomach acid or gluten or other food intolerance


Hi, thanks for your replies. I'm going to request a copy of my blood tests and get back 🙂
