It is very important to get a good night's sleep before the session. A healthy 7-8 hour sleep will help you to bear the process more comfortable, and the body to recover faster.
You should eat well before the session, it will help to avoid dizziness in the process, as well as nourish your body with the necessary energy. I recommend bringing some snacks with you, especially sweets.
Loose and comfortable clothing will help to make sure that you aren’t randomly getting itchy, overheated and it will allow you to easily re-adjust your positioning in case you become uncomfortable...
You should moisturize your skin 1-2 times a day with a moisturizing cream for 7-10 days before the session. This will ensure easy application of the ink. It is necessary to shave areas with hair on your own the day before the appointment.
Drink a lot of water, it will make your skin hydrated and prepared for your tattoo session. Hydrated skin takes ink a lot better than dehydrated skin.
Think in advance about what will help you to not get bored at the session. It can be your favorite music, series or book. Don't forget to take your headphones.
It is forbidden to take alcohol and blood-thinning drugs (aspirin) at least one day before the session. They can cause profuse bleeding during work.
