Wrensong - thanks for posting this but it is really puzzling! I've had a quick look and the sources ( including Newson clinic and other clinics) give the usually accepted scenario - that oestrogen promotes hair growth and lack of it has the opposite effect! The product info for oestrogel gives Alopecia as a potential side effect with unknown frequency though the tablets and patches that I quickly perused, do not, so I dont know how it has come to be listed under the NHS side effects unless this has been generalised from one specific HRT type maybe?
Hi Hurdity, yes I agree it
is odd & somewhat confusing
. The Estradot SmPC lists alopecia as a "rare" side effect but I can't find it listed under Evorel & haven't checked the gels or spray. I looked into it some time ago when another member was having very distressing hair loss she attributed to oestrogen use & more recently because I've been shedding more than I'm comfortable with myself.
Like Bandango, I've been dismayed to notice over time that there does seem to have been a correlation with higher doses of oestrogen, but in my case there have been various other possible contributory factors muddying the picture, inc low ferritin & the thyroid complication. When I reduced my oestrogen dose to 25mcg the hair loss seemed to gradually slow to minimal but I don't feel the benefits of HRT on a dose that low & also have osteopenia to think about. With hindsight I've wondered whether the fact the hair loss was worse on higher doses of oestrogen was due to the heavier bleeds I got as a consequence, not knowing until recently that that my ferritin had become low
. My oestradiol whenever tested had always been below 300, so never mega-high nor into the 300-500 range my good NHS gynae advised to aim for, but my uterus just seemed to lap it up
. I'm supplementing with iron, with tests to monitor progress & hoping that improving the ferritin will reduce the rate of hair loss.
Frustratingly, I felt I had to discontinue testosterone for several months as a test but found the hair loss didn't decrease during that time. My levels on T have never been above mid-range, I have no ovaries & definitely feel benefits from supplementing with T that go beyond the sexual aspects it's well known for & I don't want to be in a position where I feel I can't use it
. It's a conundrum for sure!

P.S. Kept coming back & adding to this as I thought of more!
