A pneumatic hair-conditioner system has a vacuum pump (1, 4, 6, 30) attached predeterminedly to a hair processor (2, 25, 28, 29, 31) which employs airflow to the vacuum pump for predetermined hair processing by the hair processor. The vacuum pump and the hair processor can be either a dedicated-process conditioner with permanently integral attachment and pneumatic communication of a single select processor for predeterminedly limited hair-processing use or a multi-process conditioner with detachable attachment and integral communication of a plurality of select processors for predeterminedly multiple hair-processing uses. Optionally, the vacuum pump can be reversible for blowing instead of sucking air in pneumatic communication with the hair processor. For blowing, application of heat also is optional.
