How to wash off henna tattoos?

Henna tattoo refers to Indian hand-painted henna, an ancient human body decoration art, which is popular in Southeast Asia, the Middle East, North Africa and other regions. The washing method is as follows:

1. Mix equal amounts of salt and olive oil in a bowl. Oil is an emulsifier and salt is an exfoliating agent, so this combination is very suitable for washing henna off the skin.

2. Soak the cotton ball in the oil and scrub the stains on the skin with the cotton ball.

3. When the cotton ball is dry, replace it with a cotton ball that has just been soaked.
