Abstract

Sometimes Premature hair greying occurs due to damage of physiological function of the body. The causes may be stress, inadequate nutrition, heart diseases, genetic trait, environmental pollution, smoking, and more use of hair colorant, gels and hair sprays. Premature greying can be reducing by using Amaranth Leaves. The use of lentils, spinach, vitamin B9 and copper rich food may avert hair greying. The presence of Nitrite in the urine signals the urinary tract infection. It may also link with blood in urine, cloudy urine, burning with urination, and strong-smelling urine. To specify the relation between urine nitrites and premature greying urine test was performed. We have collected almost 150 to 200 samples of urine from students. It was observed that only 41% female and 19% male having canities found positive nitrite in urine sample. While 29% female and 21% male having premature greying found negative nitrite in sample. This ratio correlates canities with presence of nitrite in urine.
