Psoriasis

Psoriasis is characterised by the presence of red, raised patches covered by silvery-white scales, which is caused by an abnormally fast cell division rate in the epidermis layer of the skin and is a genetically determined disorder. This condition often leads to increased shedding of hairs in the telogen (resting) phase of the hair cycle and some reduction in hair density.
