Hey everyone, hope all is well. As you might know Im fairly new to spray tanning , only been doing it couple of months and still fnding my feet although I have done approx 75 tans so far so Im doing ok! Ive been using Sienna X / White to Brown so far, am now looking at Unreal and products from Wow Factor and Suntana, and struggling to decide whats best for me, there are pro's and cons to each I guess. Im thinking could I perhaps get an 8% bottle and add booster drops accordingly to make a solution 10% and 12% to save me costs and stop my solution going off before ive used it all ? anyone use these drops? I know Wow Factor sell them for their Tantrick range . Just wondered if that would be ok and might save me stocking lots of different shades xx
