Skip the Big ACL traffic backup at the Rollingwood/Bee Cave Exit.
Get off Mopac one exit South of the Rollingwood/Bee Cave exit and go through the neighborhood. From the exit ramp, make an immediate (as in not much time), right onto Liberty Park Dr., then make another right at Montebello Road. Take Montebello down to Bee Cave Road and turn right. The salon will be on your right.
