Abstract
Abstract A method of setting hair in which curlers are placed in a steam chest until they reach their maximum effective moisture content at an elevated temperature. Then the curlers are removed from the steam chest, and a strand of hair is wrapped around the moist exterior of the curler. The preferred temperature at the time of wrapping is in the range of 150* F. to 190* F. The preferred curling time is at least 2 minutes.

Claim 1
Independent Claim
260 words
A method of setting hair in the absence of applying direct live steam to the hair in which the hair is wound around a hot moist curler and fixed thereto until the curl of hair is set, comprising the steps of: placing the curler having moisture and temperature-retaining characteristics iN a steam chamber out of contact with any boiling fluid therein but exposed to the steam generated in the chamber to cover the entire exterior surface of the curler with steam which condenses on said surface area and heats the exterior surface of the curler; completing the heating and condensate depositing step before the curler is placed in the hair; removing the curler from the steam chamber only after it has attained an elevated temperature substantially that of boiling water and after the curler exterior has attained its maximum effective moisture content; wrapping a strand of hair around the moist exterior surface of the curler while the curler is at a temperature within the range of 150* F. to 190* F., thereafter securing the wrapped hair in place to form a curl as the effective moisture content is transferred to the hair and the aforesaid temperature range traversed thus transferring said heat and moisture from the exterior surface of the curler to the inside of the curl and through the curl toward the outside atmosphere; and keeping said curler in the hair with the outer portion of the curl exposed to the outside atmosphere for at least 2 minutes until the hair is set and the moisture dissipated by evaporation.
