Tipping Etiquette?

First off I’m a server so I know the importance of tipping but, I’m just not sure in this situation.

The guy who cuts my hair had a bigger salon but all his employees left for other salons over a year ago. Since then he has moved out of his big salon and into a one room salon and the only other employee is his receptionist.

My question is should I keep tipping so much since he is the owner. I still pay the same $25 for a mens haircut + $8 tip.

I’m going to keep tipping no matter what I just wanted to know what you guys thought.
