It’s notable that smoking cigarettes increase the risk for heart disease and lung cancer. The drawn-out impacts, nonetheless, can go past the heart and lungs and affect hair. Smoking tightens blood vessels, which can decrease the bloodstream to hair follicles and cause baldness. Moreover, tars in cigarettes can harm portions of your body, including your hair follicles, causing early gray hair.

These vitamins play an essential role in your cells, most notably the red blood cells, which help carry out the oxygen to cells in your body., including the hair cells. This deficiency of vitamins causes the weakening of hair and drastically affects the production of melanin.
Hypothyroidism and hyperthyroidism are the hormonal changes seen in the body caused by the thyroid glands. These abnormal changes in the hormones lead to premature gray hair. At the base of your neck, a butterfly-shaped gland is presently called the thyroid gland. It plays a role in metabolism. The changes in the thyroid gland tremendously affect hair growth and hair color. The difference in the production of thyroid hormones leads to abnormal changes in melanin production, which leads to the formation of gray hair.
Autoimmune disease can likewise cause gray hair. This is the point at which the body’s immune system assaults its cells. In conditions like alopecia and vitiligo, the body’s immune system attacks the hair and causes the loss of pigments.
