Eczema, seborrhea and psoriasis are all conditions that cause red eruptions often with scale on the skin and scalp. Eczema is found most anywhere on the body while seborrhea looks similar but involves sebaceous (oil) glands of the skin and psoriasis can be found anywhere but is usually on elbows and knees. All three are an inflammation of the skin and this is called dermatitis. None of the three is contagious.
