I've been thinking of ways I can upgrade and add more interest for clients booked in for a full-head of tint. I allow myself 30 minutes for application and mixing so it couldn't be anything too time consuming.
What do you all do? Preferably I don't want to have to charge extra, I just want to give them something more they can't do at home
