When skin becomes itchy it is common to feel the need to scratch the area. Scratching can best be described as rubbing or scraping the irritated area with fingernails or another object. The act of scratching is actually quite scientific and causes an override of nerve signals. To put it simply, when you scrape or rub an area of your skin that feels itchy, your brain is only able to feel the sensation of the scratch and no longer notices the annoying itch. While scraping or rubbing can provide relief from itching, this relief is only temporary. Similarly, too much rubbing can result in skin damage. When dandruff causes itching, individuals need to remain cautious that they are not causing additional wounds to their scalp.Next
