During the healing of the tattoo, it is better to use liquid neutral soap and if it is a bar soap, do not share it with other people..
warm or hot water will help you remove everything that has excreted from the wound caused by the new tattoo. Be careful, the newly tattooed skin will be sensitive to high temperatures.
Rinse well with running water and do not leave traces of soap or other chemical products (shampoo, conditioner,...) in contact with the wound.
DO NOT use the same towel you have used for your body, toilet paper or wet wipes, and do not share towels with other people.
