         4 : The method for hair dyeing or bleaching according to  claim 1 ,
 wherein a discharge port of the pump foamer container is formed to have an angle θ between a perpendicular line of an opening face of the discharge port and the vertical direction being in a range of from 0° to 70° in a state that the pump foamer container is upright.   
     
     
         5 : The method for hair dyeing or bleaching according to  claim 1 ,
 wherein an area of a discharge port of the pump foamer container is in a range of from 45 to 200 mm 2 .   
     
     
         6 : The method for hair dyeing or bleaching according to  claim 1 ,
 wherein a maximum load until a pump head of the pump foamer container is completely depressed in a state that the liquid mixture of the first agent and the second agent is stored in the container body is in a range of from 10 to 25 N.   
     
     
         7 : The method for hair dyeing or bleaching according to  claim 1 ,
 wherein a pump head of the pump foamer container takes time for from 0.2 to 3 seconds until being returned to an original position before depression when a depressed state of the pump head is released in a state that the liquid mixture of the first agent and the second agent is stored in the container body after the pump head is completely depressed.   
     
     
         8 : The method for hair dyeing or bleaching according to  claim 1 ,
 wherein the pump foamer discharges a mass of 8 g or less per single depression operation.   
     
     
         9 : A two-part hair dye or bleach kit comprising:
 a two-part hair dye or bleach composition comprising a first agent which comprises an alkaline agent and a second agent which comprises hydrogen peroxide;   a container body in which liquid mixture of the first agent and the second agent is to be stored; and   a pump foamer which is to be attached to the container body and which discharges the liquid mixture in a foam,   wherein a pump foamer container is completed by attaching the pump foamer to the container body,   at least one of the first agent and the second agent comprises a foaming agent,   a viscosity of the liquid mixture is in a range of from 1 to 300 mPa·s at 25° C., and   a discharge mass of the pump foamer container per single depression operation is 1 g or more.   
     
     
         10 : The two-part hair dye or bleach kit according to  claim 9 , further comprising:
 a container body in which the first agent is present;   a container body in which the second agent is present;   the container body in which the liquid mixture of the first agent and the second agent is to be stored; and   the pump foamer which is to be attached to the container body,   wherein the pump foamer container is completed by attaching the pump foamer to the container body storing the liquid mixture of the first agent and the second agent.   
     
     
         11 : The two-part hair dye or bleach kit according to  claim 9 , further comprising:
 a container body in which the first agent is present;   a container body in which the second agent is present; and   the pump foamer which is to be attached to the container body in which the second agent is filled,   wherein the pump foamer container is completed by pouring the first agent into the container body in which the second agent is filled, followed by attaching the pump foamer to the container body.
