Generation X, or Gen X, is the demographic cohort following the baby boomers. There are no precise dates for when this cohort starts or ends; demographers and researchers typically use starting birth years ranging from the early-to-mid 1960s and ending birth years ranging from the late 1970s to early 1980s.
Causes of Scalp Psoriasis. Like other forms of psoriasis, scalp psoriasis occurs when your body's immune system misidentifies the skin as being foreign. Under normal circumstances, the body makes white blood cells, called T-cells, which should only attack invaders such as viruses, bacteria or fungi.
Psoriasis typically starts or worsens because of a trigger that you may be able to identify and avoid. Factors that may trigger psoriasis include: 1  Infections, such as strep throat or skin infections. 2  Injury to the skin, such as a cut or scrape, bug bite, or a severe sunburn. 3  Stress. 4  Cold weather. 5  Smoking. 6  Heavy alcohol consumption.
