These should be done BEFORE your spray tanning session.  It is important to not get wet for up to 12 hours following your tan. Even having a spa pedicure days after your tan can exfoliate your lower legs faster and cause uneven fading. Waxing, as well as hair color, will remove the tan from the area applied. 

When should i get my manicure/pedicure done or waxing or my hair colored?
