This beauty salon is great. It is located in Dupont Circle, just near the Starbucks off of the circle. The place is not super cheap, but the haircuts and stylists provide excellent cuts. The place is usually busy, so you will probably need to schedule an appointment. The location is great though because you can take the metro there and check out some stores while you wait. Overall, I would recommend this place if you are wiling to pay a little more for a better cut.
