Thanks for your reply - do you think that the zinc levels could be low enough to justify abnormal hair loss though?
I've had a scalp biopsy and it said no signs of androgenic alopecia. In fact my scalp looked healthy apart from some fungal spores. My hair is shedding a lot though!
My ft3 levels are 4.3 on ref 3.5 - 6.8
And ft4 13.3 on reference 12 - 22
Could my low copper and zinc be linked to low thyroid and hairloss?
