I know what you mean! Apart from filling in my part of the consultation form, I send out my text reminders for the next day. I offer a half price brow tint with a lift so if they go for that, I do their brows while the pink is on. I've also been known to create before & afters of other lifts on my app ready for my page, and even add things to my page for publishing (but schedule for later )
If they chatter then I do less tbh x
I offer add ons to the Lash lift that can be carried out in the processing times. So foot massage,scalp massage, hand/arm massage. Or shape and paint on fingers/toes. I charge at a reduced rate. It increases your income and the client finds the treatment more relaxing too.
I offer the same a head massage or some Reflexology or hand and arm massage or could a nail file and polish. Blue black has much more definition - think of the difference between a black bird or a raven or jackdaw. The latter have much more darkness and depth.
