I highly recommend Debbie from Hair Studio Sonterra - http://www.hairstudiosonterra.com/

She's super flexible, does a fantastic job, and, as my posts here on the forum have proven, she's an all around great stylist. I'm 28, nobody has ever detected me. She even helped me make my very first template when I was a clueless wearer.

Average price is about $45, but I usually tip her a $20. Located on the North Side, in Stone Oak.
