To remove a black henna tattoo, soak it in salty water for 15 minutes, scrub the tattoo with a large-grained exfoliating scrub, and rub the tattoo with a loofah sponge. Repeat this 30-minute process daily until the tattoo disappears. The required supplies are water, salt, a hand towel, exfoliating body polish, a mirror and a loofah sponge.
- Soak the tattoo in salty water
Soak the tattoo in a bowl of warm water mixed with salt. If the tattoo's size or location makes immersion impossible, cover it with a clean hand towel that was soaked in salty water. Keep the tattoo in contact with the liquid for 15 minutes, then rub it vigorously with a towel.
- Apply body polish
Cover the tattoo with a liberal amount of coarse body polish. Rub the polish into the henna for several minutes, then rinse with hot water.
- Scrub the tattoo with a loofah
Hold a loofah sponge under warm running water, squeeze it out, and rub it over the black henna tattoo. Scrub the skin for up to five minutes, stopping earlier if you experience pain. Rinse the loofah, wring it out, and let it air dry.
- Inspect the tattoo
Inspect the tattoo site to gauge your progress. Most black henna tattoos take several days to disappear completely. Repeat this procedure every day until the design is gone.
