There are a lot of discrepancies over what is best. I don’t know what is best, but I know what I did.
Wash it with unscented Dial antibacterial soap when in the shower, keep it moist during the day using A+D Ointment, this went on for about a week, then into the second week I used unscented lubriderm lotion to keep it moist.
The total healing time was a little under two weeks.
Do not pick at the scabs even though they will be itchy, discolored (from the ink) and tempting.
Do not panic if some colored (from ink) skin peels off, it will be ok.
Also, you should call the tattoo parlour/artist and see if they have any other personal suggestions, but as long as you keep it clean it will not get infected and eventually be a beautiful and healed tattoo.
