Devonshire Street is the direct line: head east from Chatsworth and drop south on Lindley Avenue. Coming from near the Chatsworth Metrolink or the industrial side of town, Nordhoff Street is the alternative and usually the quieter of the two.
It is a genuinely short trip for most of Chatsworth, and worth it if you want a salon that does proper custom design work rather than a standard set.
