Abstract
A permanent-wave treatment method which can give a permanent-wave comfortably without using a cap or a turban, and a treatment auxiliary agent used in this method. The permanent-wave treatment method comprises a winding step of applying permanent-wave treatment liquid to hair and winding the hair around rollers, and a liquid drop prevention step of sprinkling a powdery treatment auxiliary agent on the wound hair so as to prevent the permanent-wave treatment liquid from dropping. The treatment auxiliary agent comprises powder which adsorbs or partially dissolves in permanent-wave treatment liquid, and serves to increase the viscosity of the powder-sprinkled permanent-wave treatment liquid and prevent the permanent-wave treatment liquid from dropping.

A method of preventing the dropping of the liquid agents of a permanent waving treatment of hair comprising, in sequence, the steps of:
- (1) applying a first liquid agent comprising a reducing agent to the hair for a period of time sufficient to reduce the hair;
- (2) winding the hair onto hair rollers;
- (3) applying a second liquid agent comprising an oxidizing agent to the hair for a period of time sufficient to oxidize the hair;
- (4) rinsing the hair with water;
- and
- (5) the additional step of applying an auxiliary agent comprising hydrophilic organic powder having as a hydrophilic group a hydroxyl, carboxyl or ester directly to the hair as a dry powder either before or after step 3 but before step 4 above, and leaving the auxiliary agent upon the hair for a period of 5 to 15 minutes sufficient to absorb any excessive liquid agent.
