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.
Several types of psoriasis exist. These include: 1  Plaque psoriasis. 2  The most common form, plaque psoriasis causes dry, raised, red skin lesions (plaques) covered with silvery scales. 3  The plaques itch or may be painful and can occur anywhere on your body, including your genitals and the soft tissue inside your mouth.
