Your hair follicles depend on ferritin (iron stores) for the oxygen they need to grow. When it drops too low, hair growth is the first thing your body shuts off.
FerraVital gets your ferritin above 70 — the level where research has proven hair actually grows instead of falling out.
Women are seeing shedding slow by week 6. Baby hairs by week 8. The thin spots that looked permanent? Finally filling in.
