You say shalom back. Shalom means hello. If you say "Shalom Shalom," it means mays Bye bye.

Shalom is the reply to shalom.

Shalom Shachna Czerniak has written:

'Mishmeret Shalom'

Shalom is the Hebrew word for peace. Shalom is used as a greeting like "hello" in English. "Shalom shalom" is often used like "bye bye" is used in English.

The repetition of a word is used for emphasis. Biblically, 'shalom shalom', has been translated, 'perfect peace' (see Isaiah 26:3). The thought is complete peace, total peace.
