THE PRESENT INVENTION IS A METHOD FOR HAIR DYEING OR BLEACHING BY DISCHARGING IN A FOAM FROM A SQUEEZE CONTAINER (6) A MIXED SOLUTION OF A FIRST AGENT (A1) AND A SECOND AGENT (A2) OF A TWO-PART HAIR DYE OR BLEACH COMPOSITION TO APPLY ON THE HAIR. IN THE PRESENT INVENTION, THE SQUEEZE CONTAINER WHICH INCLUDES A CONTAINER BODY (4) AND A SQUEEZE FOAMER (5) IS USED AS THE SQUEEZE CONTAINER (6). AT LEAST ONE OF THE FIRST AGENT (A1) OR THE SECOND AGENT (A2) CONTAINS A FOAMING AGENT. THE MIXED SOLUTION OF THE FIRST AND SECOND AGENT HAS A VISCOSITY (25ºC) OF FROM 1 MPA·S TO 100 MPA·S. THE FIRST AGENT (A1) AND THE SECOND AGENT (A2) ARE MIXED IN THE CONTAINER BODY (4) SO AS NOT TO PRODUCE A FOAM. SQUEEZING IS CARRIED OUT WITH THE SQUEEZE CONTAINER (6) STOOD UPRIGHT SO THAT THE MIXED SOLUTION (A3) DOES NOT REACH AN AIR INDUCT PATH (12) OF THE SQUEEZE FOAMER (5). AS A RESULT, THE MIXED SOLUTION OF THE FIRST AND SECOND AGENTS (A1, A2) OF THE TWO-PART HAIR DYE OR BLEACH COMPOSITION CAN BE STABLY DISCHARGED IN A FINE FOAM USING A SQUEEZE CONTAINER (6).
