This is a genetic condition
characterized by red, raised patches with white, scaly lesions
caused by excessive shedding. Psoriasis is usually found on knees, elbows, hands, and scalp. A coal tar ointment like Tegrin Lotion for
Psoriasis or Doak Oil Forte Therapeutic Bath Treatment will help.
You can get a stronger ointment by prescription. Denorex and
Tegrin make several shampoos with coal tar. You can also try
dabbing vegetable shortening like Crisco on the outbreak. Crisco
is a wonderful folk remedy for all dry skin problems.
