As a 'natural' blonde, I have trouble finding salons that offer highlights at reasonable prices. Bubbles is one such locale that offers a quality product without breaking the bank.
When planning a trip, allow for a couple hours, as the store is busy, often leaving multiple customers waiting as one stylist works on each in shifts. While this can be disconcerting, it does offer a chance to catch up on the plethora of magazines available and peruse of the variety of products Bubbles offers.
This is a great salon if you're new to DC, but not a location for building long-term relationships with stylists. There is a high turnover rate of staff, and sometimes, you just don't want to spend 3 hours reading People Magazine.
