So normally when I get my hair cut I leave a decent tip (I have really long hair) but this time when I'm going to the salon I'm getting a haircut, chemical treatments, and I am also getting my eyebrows shaped. The haircut is about $60, the chemical treatment is about $25, and the eyesbrows are about $20. What's a good tip to leave, and if more than one woman does them all who do I tip?

Ask the manager, or person that runs the office, what the typical and/or standard tip is.

Alternatively, treat it like a restaurant: 15-20% (which is typical for Salons where I live (where my wife goes).
