Hi all. I have recently started spray tanning and its going well so far. Just had a client a couple of days ago that loves the tan but wants to go darker so I offered her a re-spray. I used 10.5% fresh indulgence at the time. Will it come out darker if I do another layer of 10.5% or should I re-spray with the 11.5% ? Not sure what to do. Any help would be greatly appreciated. thanks
