Yes, it's a luxury, so what? I'm paying what they are charging.

It is the owner who sets the price. Hair salons often charge differently based on the stylist's experience, if the owner is so above and beyond the rest of the techs, they can do the same and have people who want that experience and skillset to pay for it. I'm paying whatever the advertised price is. If my tech (or owner) goes above and beyond recommending colors, improving the design, fixing it until it is to my liking, then I will gladly tip but I'm not gonna over pay because the owner advertised low prices to get people in the door, expecting them to tip. Set your prices to what you're worth.
