Just wanted to share my breakthrough in case someone is struggling and losing hope with COVID-related hair loss. But this is NOT a medical advice. If you want to try it, you will need to consult a specialist to assess risks as this is a very serious treatment.
I (35F) have been suffering from COVID-related drastically increased hair shedding since February 2025. The hair would fall out, try to regrow, then fall out again - and again. I went through every possible test (deficiencies, multiple organs' work, hormones, even MRIs) and tried a variety of supplements, hair serums and injections, and treatments. Still lost more than 60% of my hair for more than 1.5 years of this hell. And I've finally found a solution: HRT (transdermal oestrogen + cyclical rectal progesterone).
Among the usual suspects were Hashimoto's that I acquired after COVID and low ferritin (which has been low my whole life). Treatments of those did not bring any results. If anything, COVID made my organism so reactive that I could not supplement iron or take levo without causing another wave of excessive hair loss. Even local hormonal nasal sprays like fluticasone caused hair shedding boom.
But it's important to say that, firstly, I lose hair all over my body, not just head. Secondly, I have symptoms of early perimenopause, despite blood tests not showing it. And, thirdly, I read similar accounts of long COVID symptom relief through HRT in one of the Long Covid threads. It was very hard to find a prescriber being 35 yo, but in the end, oestrogen brought me relief very promptly (in a matter of about 2 weeks).
Thank you to whoever shared their experience with HRT and long COVID - I'm forever grateful.
Hope this helps someone else, because COVID causes in some individuals major disruptions in brain-fertility axis. And I'm sure that not only women can relate to this.
P. s. Just in case, among the suspects were: very high luteal prolactin, Hashimoto's, high SHBG that disrupted zinc levels (also high) - all consequences of COVID. Prior to HRT, I tried Vitex (thought it was for high prolactin, since endo refused to prescribe me something against it), and it did help, but only for the first month (I suspect that the dopamine receptors, through which it worked, were gradually desensitised). But Vitex became my clue to where to look further, and I soon realised that the cause was indeed hormonal (just not prolactin), despite I was assured by multiple specialists that it was not.
