Can Low Iron Cause Hair Loss?

Yes, low iron levels can cause significant hair loss, particularly in women. Iron deficiency affects approximately 25% of the global population and is strongly linked to telogen effluvium, a condition where hair prematurely enters the resting phase. Studies show that women with iron deficiency are 2-5 times more likely to experience hair thinning. Your body prioritizes iron for essential functions like oxygen transport, leaving hair follicles with insufficient resources. Hair loss typically occurs 2-3 months after iron levels drop, affecting hair density and growth rate. If you're experiencing unexplained hair loss, consider getting your ferritin levels tested, as early detection and iron supplementation can help restore normal hair growth patterns.
