hi all I had a new client for a spray tan who is around dress size 30. I ended up using 230ml of tan on her which is 1/3 of my bottle. I usually use around 100ml per person. She wants to be a regular client now but I can’t believe how much product I’m using for her. Would you charge more and if so how would you go about saying it. It’s not really worth my time/money on product but I feel awful bringing it up with her.
