These inflammatory skin conditions, while not life-threatening, can make daily life quite uncomfortable. This condition of severe itching, dryness and scaliness results when these oil glands become clogged and inflamed. The cause of the recurring condition is unknown. Scratching the area can actually worsen the problem. Psoriasis is a skin condition that can be found anywhere on the body.
Scientists believe it is a result of a gene that is passed down through families.
Those with psoriasis can have new cells coming to the surface approximately every four days. This hyper-proliferation of cells causes them to bunch up at the surface, taking on the form of large, thick, white scales and sheets of skin that actually slough off in these large sheets. The bunching of the skin cells at the surface of the skin can lead to intense itching which, again, can be exacerbated by scratching. The scalp is an area where psoriasis often occurs. In the case of these conditions, some dandruff shampoos will not help the situation, or they may provide only very temporary relief.
