“Secrets of a Stylist” (8 p.m., HGTV) may sound like a show set in a hair salon, but it’s the new showcase for Emily Henderson, the winner of season 5 of “HGTV Design Star.”

People used to watch HGTV to learn how to fix their kitchens themselves. Now they tune in to see HGTV audition people to appear on other HGTV shows. If you still want to learn how to grout, turn to DIY, where the hosts merely aspire to HGTV status.

Most people have a personal style, or a desire for one. A former prop stylist, Henderson helps homeowners get a handle on their own tastes with a procedure she calls a personalized “style diagnostic” that is not unlike the Q&A process involved in online dating sites. This comes in handy when trying to coordinate the personal preferences of a couple.

In the first episode, she encounters a couple who agree on little except a shared notion that their decor just doesn’t work. Using her design audit, she determines that while the wife prefers “Hollywood Regency,” he’s more given to “Country Club Chic.” Can their styles blend? Can this marriage be saved?
