Iron deficiency is a common cause of hair loss. Iron is essential for producing hemoglobin, which carries oxygen to cells that stimulate hair growth. When iron levels are low, hair follicles may not receive enough oxygen, leading to weakened hair strands and increased shedding. This can result in noticeable hair thinning or even hair loss over time. Addressing iron deficiency through diet or supplements can help restore healthy hair growth and prevent further loss.
