I tried these on doc’s advice for anaemia and hair loss and they really do work, not only do they address iron count but my hair is now noticeably thicker. I no longer have v heavy periods, a symptom of anaemia. Try them for at least 6 months, if you’re really anaemic it will take time to get your blood levels back to normal, maybe longer but they have made a huge difference to the volume of my hair. It’s not back 100% to it’s original thickness but at my age I don’t expect it to be, just happy that it’s growing again and looking healthier. Give them a go and be patient!
