Haircut day (please correct)

Today was the my haircut day. (A little awkward--you can also say, "Today I went to get my haircut" or "Today was the day I went to get my hair cut.)
I do it every two weeks - My hair grows fast.
I phoned to make an appointment but no one picked up.
I went there anyways. Fortunately, there were no customers.
I parked my car across the street because there is no parking at the hair salon.
I sat comfortable comfortably in the chair and my/the hairdresser asked me, "How would you like me to cut it?"
I replied that I'd like only a to trim the sides parts. 
My visit was brief and not expensive.
It took me  less than 10 minutes.
