I've been losing hair since 2 years now particularly in the middle part, on temples and hairline I already have very fine and thin hair. I've really low ferritin levels - 9ng/l and vit D is low as well but my derm has suggested me to use minoxidil 5%, hair serum (redensyl) and supplements . My mom has thinner hair and some hair loss overall on the scalp but no widening of middle part so she does not have AGA. I'm not sure if i continue to use minoxidil or just vitamins
