I’ve also had very fine hair but now I’m 52, my scalp is noticeably visible especially around my crown.
Covid really knocked me for 6 and I had a lot of hair loss after that. I’ve had all sorts of blood tests and all my vitamins and minerals are at normal levels.
I suspect this runs in my family as my mum lost a lot of hair but then she went on to get cancer and died quite young so I’m not sure what her hair would have looked like at my age!
I have v sensitive skin so don’t want to try the creams - did you just give in to it? I’m cutting it shorter and shorter as it just looks ridiculous long but not sure what more I can do!
