When the X-ray treatment is not available, or where only small patches are present, the crusts should be removed by keeping the scalp soaked in spirit or boracic lotion under oiled silk, or by constant swabbing with oil or petroleum, or by poulticing. After the removal of the crusts the hairs
should be industriously epilated by forceps, a definite area being attacked each day, and any of the above ointments rubbed well into the empty follicles.
