Since all imperfections are rightened sa pamamagitan ng vampire venom, does that mean a tattoo would dissappear when the human who had it became a vampire?

Well for the hair part I'm waiting to see Eclipse, because Rob's hair is shorter in New Moon. (That's possible because he could have cut it) But... what if his hair is longer in Eclipse... that's something to think about

And since we’re talking physiology…I’ve had tons of people ask if Bampira can have babies. The answer is no. When someone becomes a vampire, it’s as if they are nagyelo exactly as they are in that moment. His or her (and we’ll go with her because it’s madami central to this discussion) body no longer experiences change. Hair does not grow, nor do fingernails (if you cut your hair, you’re stuck. That’s why Alice’s hair is so short–it was growing back from being shaved in the asylum). This applies to all changes–so a woman would no longer have any kind of ovulation cycle. If she were already pregnant when she was bitten, both she and the fetus would be nagyelo in that state. - what SM wrote about that subject ( another thing is movie.. they can't get his hair to look exactly like the first time)
