Poor blood flow due to stress is also tagged as one of the main culprits of hair loss. A tight scalp due to stress prevents the scalp's blood vessels and other vital nutrients to reach the hair follicles thus jamming the passageway for hair growth possibilities. Other contributory factors that lead to hair loss are hereditary in nature. Hair loss genes may be inherited from both parents. Age may also be one of the causes to this intimidating problem. As an individual grows older, his total hair volume will decrease, even if there are no bright ideas as to the hair loss dilemma.
