Funeral cosmetology, also known as mortuary makeup or restorative arts, sometimes known by the older name desairology, are activities related to the practice of viewing a deceased person in their open casket prior to burial. If a family requests a viewing, the funeral director will discuss with the family how they would like the decedent to appear, and even ask the family to provide a reference photo of the deceased. This photo may be given to the desairologist. A decedent's usual hairdresser may also be called upon.
