Hi all Hopefully not a duplicate search. I would appreciate if you could let me know for what needs to be checked in the blood when suffering from hair loss. Doing my research i came accross the following things to check: Hormones Testosterone SHBG FAI TSH FT4 Inflammation Marker CRP-hs Iron Status Ferritin Is that all or do you think something is missing, e.g. Vitamine D? Many thanks for your assistance!
