Step 1 - Set the pen to the on position, remove the lid and press the top several times to start the dye flow. Ensure the dye appears before starting application. 

Step 2 - Apply the pen to any grey hair or beard strands. Apply in the direction of the hairs. Avoid getting any dye on the skin where possible. 

Step 3 - Leave the dye for a few minutes to dry. Refrain from touching the treated area to avoid smudging. You can apply more if necessary.
