Thank you all for your words of encouragement and reminder that no problem is big enough to warrant fleeces and elasto-slacks. I take a strange hotchpotch of supplements (immeden, or whatever that stuff is Christy Turlington advertises, an SSRI, some tablet for HRT, cod liver oil, Vit D and some sort of multivit).
Change is gradual-ish, but markedly worse over past 4 months or so.
If I stop dying my hair it will go GREY in which case we can refer back to earlier comments about fleeces
I am extremely lazy so tend not to use dryers/straighteners etc. much.
Wondering about the iron/anaemia thing .Unlikely ,but not impossible and anything worth a try.
I have started waiting for my hair to dry before brushing (and then doing so v. gently), but tricky to let it sit there in wet, matted, frizzy state for ages.
If oestrogen/menopause related, then I would have thought the HRT would offset it, no?
