How to do the patch test is as follows:

    (1) Prepare agent 1, agent 2, a small tray, swab and tissue.
    (2) Take out some agent 1 and agent 2 and mix them with the swab. (The hairdye used must be stored with its cap tightly closed.)
    (3) Apply the well mixed test sample (liquid) on the skin at the back side of an ear or around hair, and dry it for 48 hours.
    (4) If you feel rash, itch, blister or stimulus on the tested spot, wash out the test sample immediately. If you experience this, never start the hairdye procedure.
