shaving after spray tan

Question: as when you shave your legs and you have a spray tan, the hair on your legs grows back, but when you shave your legs the tan begins to come off????
would it be better if i waxed?

Question: Yes, waxing would be better, and it is best to wax two days before spray tanning, so the pores have a chance to close properly. If they don't, spray tan solution can wedge itself in the pores giving you a spotty look.

You can still shave after a spray tan, but do it very lightly, on a dry skin and with the hair growth, not against it. You will still have some stubble, but at least it will not be long hair. Afterwards moisturize with the tan extending lotion, and that will give your tan a boost and repair any minor damage.
