Hair loss often signals a variety of medical problems and could be the result of a low amount of red blood cells in your system. This condition is called anaemia. The body needs certain nutrients to produce more red blood cells and if there is a lack of one or more of these nutrients, anaemia will develop.
The hair follicle and root are fed by a nutrient rich blood supply. When iron levels (serum ferritin) fall below a certain point, you may experience anaemia. This disrupts the nutrient supply to the follicle, affecting the hair growth cycle and may result in shedding.
