Hair Casts

Hair casts are cylindrical (tubular) material that sometimes surround hair follicles. Hair casts are said to be "primary" in nature when not associated with an underlying scalp disorder and "secondary" when associated with an underlying disorder. Many inflammatory conditions can be associated with hair casts including seborrheic dermatitis, psoriasis, pityriasis amiantacea, traction ... and others. The patient in this photo has hair casts from seborrheic dermatitis.
