I charge £35 for a choice of three treatments. They can choose from nail paint & polish, mini facial, back massage, thai foot massage, eyebrow tint & shape, hot stone taster, scalp massage.
They have a mini session of each - 20 min, totalling 60 mins treatment time. The clients think it fantastic - they are getting 3 treatments. From my point of view it is still only an hour of time and minimum product useage, so it is a win win.
Hope it all works out for you.
