Tipping salons

I’ve always wonder if your suppose to tip the hair dresser?

I always think we’ll their prices range from 120 to 200 depends on hair color!

They definitely know their making money because they have to charge where they can profit! So I always thought that tips are included I just feel like now days everyone wants a tip for the most minimum things!

I know that it takes time but in that case all jobs should be like that because I take my time to help people so not sure what do you guys think?
