Chronic itching and excessive hair loss are two major health problems that are seen in many people at the same time. Although these two may usually seem like separate problems, these two symptoms often appear together when there is a deficiency of some important vitamins or hormonal changes in the body. Nervous system disorders and poor blood circulation lead to this. Here are the 5 main scientific reasons behind it:
Vitamin B12 and B7 (Biotin) deficiency (Nutritional Deficiencies): Vitamin B12 is essential for building the ‘myelin sheath’, the protective layer of our nerves. When B12 is lacking in the body, the nerves become weak and severe tingling and numbness in the limbs (Peripheral Neuropathy) occurs. Along with this, when biotin (Vitamin B7) and iron, which are essential for hair health, are reduced, the hair roots become weak and severe hair loss occurs.
Thyroid disorders (Hypothyroidism): The thyroid gland in the neck produces hormones that control the body’s metabolism and cell growth. In a state of low thyroid hormone (Hypothyroidism), hair growth slows down completely and hair falls out in large quantities. This condition also causes fluid to accumulate in the body, which presses on the nerves in the hands and feet (for example, Carpal Tunnel Syndrome) and causes severe numbness.
Diabetes and diabetic neuropathy: Prolonged high blood sugar levels damage the small blood vessels and nerves in the hands and feet. This is scientifically called diabetic neuropathy. This can cause severe numbness and tingling in the feet. Along with this, reduced blood flow and hormonal changes in diabetic patients can also cause hair loss.
Anemia & Poor Circulation: Anemia is a condition in which there is a decrease in blood in the body. When hemoglobin in the blood decreases, not enough oxygen and nutrients reach the hair roots in the brain and the tips of the limbs. As a result, hair falls out rapidly and the limbs feel cold and clammy.
Severe mental stress and hormonal changes: When there is chronic severe mental stress, the body releases a large amount of the hormone Cortisol. This stops the hair growth phase suddenly and causes massive hair loss (Telogen Effluvium). Severe stress also causes temporary hair loss by tightening the muscles. These symptoms are also seen in women with PCOS and postpartum period.
